Geo - Prizm :: 1991 - Misfire Post Transmission Replacement
Oct 13, 2013
I've got a 91 prizm where on a recent roadtrip the transmission went out on the freeway. While driving 75mph, i heard a quick ping sound, then a quick wheel skip followed by the sound of my transmission turning itself into gravel. We had just enough time to get off to the side, but i knew it was done.
I live in San Francisco and don't feel like getting a new car only to get it covered in dings from all the bad drivers around here. So naturally i replaced the transmission in my 22 year old car. yikes. It needs to be stated at this point that the car has run flawlessly it's entire lifetime and I'm the original owner - had no reason to expect otherwise after replacing the transmission.
The shop that changed it was a large shop, AAA recommended and Owner-operated. They told me the transmission was from a car from Japan where transmission replacement is standard. (I did not know this).
Now however, the car has a misfire. No perceivable misfire for the first two minutes she's running, but then constantly misfiring every couple seconds. At stop lights, you can feel the car almost want to stop, but then step on the gas and runs ok, but can still feel the misfire until she gets up to speed. The car runs just a smudge rougher so we believe it's still misfires while at speed, just not noticeable.
Timing belt only has 10,000 miles.
Timing is dead on.
Wires are good, just changed the distributor, coil and plugs. As i understand it, the throttle position sensor is integral to the distributor, so that's new as well.
Fuel pressure is right on.
No warning lights on dash.
At this point, I can't keep throwing money at her. The transmission was 5-6 months of a car payment for a new car. Would there be a reason that the car would have a misfire after getting the transmission replaced?

I have a 1991 Ford F150 I bought. Told the transmission was shot, long story short, found out it was just a bad clutch. Pulled the transmission, replaced the clutch, pressure plate, and throw out bearing. Put everything back together, now i cant get the clutch to fully disengage. Had good pressure prior to replacement of the clutch, still has some pressure. just doesn't have enough to disengage the clutch. pulled the inspection cover, and verified the slave is moving. What is causing this issue?

I recently had my rear engine mount replaced on my 2004 Acura TSX. It was originally identified by the original dealer as requiring replacement and when I took it to anther Mechanic he also verified this and during the replacement he showed me the original engine mount which had a definitive crack.
After installation the Mechanic indicated that the car would feel a little stiff for a while and would smooth out over time. What I found after the first couple of days is that the engine seems to have a significant vibration when I am in idle or after I brake. When the car is in motion there is still a vibration but it is not very noticeable. I just remember from prior feel of the vehicle. This vibration did not exist prior to replacing the rear engine mount.
Is this expected to be normal until I put miles on it. The Acura is a 2004 but only has 75,000 miles. I don't drive it very much but I am concerned that the vibration I feel when I brake may be creating additional damage.

I just had the timing belt (water pump and thermostat) replaced in my 2004 V8. I drove it home from the dealer (75 miles or so) without incident. Drove it to and from work (4 miles) without incident for a few days.
Last night I drove ~5 miles, idled in a parking lot for ~10 min and then drove another 5 miles and it overheated. Once I shut off the car it would not come back on. I waited for it to drop below 200C and it still didn't start. Electric consumers would come on all was well....but no start.
Car was towed to the local VW dealer who do not have a phaeton tech. After the hour and half it took for the tow truck to arrive and half an hour to tow it....it started up.
I am now thinking about my next move. As I read through everyone's overheating experiences they are mostly
1. Failed thermostat (which one? does the bottom thermostat control water pump operation?)
2. Fan issues
3. Air in the coolant line following a flush (could be, but I drove it home in the cold on the first day with the heater on)
4. False readings due to a bum (upper?) thermostat.
I have a VCDS but have not been able to get out to the car to give it a shot.

I recently replaced the head gasket on a 95 Geo Prizm. Now when I tried to start it, all I get is the starter clicking. I tried tapping the starter solenoid, to no effect. The only electrical that I messed with during the head gasket replacement was to disconnect the battery.

We recently purchased a 1991 Minnie Winnie (Winnebago) which rests on a 1990 Ford E350 chassis. It only has 58k miles. While driving on the freeway or highway, the Overdrive starts to go in and out; downshifting and upshifting willy nilly. It has a manual button for turning off the Overdrive and when I do this, it stops jerking and drives smooth. But, of course, this effects the gas mileage significantly. I took the Minnie to a garage recommended by the company I purchased the Minnie from. They replaced the manual Overdrive switch and replaced the transmission with a rebuilt Ford transmission.
We got it back and it was okay for one trip but by the second trip, it was doing the same thing again. I took it back to the garage and since it was under warranty, they put in a new rebuilt transmission, another new Overdrive switch, a new fuel sensor and checked the wiring but it still had the same problem. So they sent the onboard computer board to Ford who rebuilt it. The guys at the garage thought for sure this would resolve the problem. It didn't. They have exhausted their ideas as to what is causing this problem. We love the Minnie Winnie and other than this problem it is in beautiful condition.

1991 Honda Auto trans, 247k miles. We now have the third transmission in the car and it still does not shift into over-drive-4th. Odds seem poor that all 3 were actually bad.What now?

I have been hoping this problem would go away but it hasn't. I drive a 1991 350 diesel with Banks turbo and transmission module. When we first bought the truck it was only a few thousand miles before we had to have the tranny rebuilt. It was fine for about a year or two when we installed the Banks turbo and then after about five thousand miles the torque converter flew apart and ruined everything inside the tranny.
After this second rebuild it seems to be doing pretty good all except for it wanting to shift in and out of overdrive for no reason. I can have the cruise set on anywhere from 50-65 and when I start up a VERY slight hill it will downshift to third. I know that this engine has plenty of torque to maintain its speed up these small hills without downshifting so something isn't right. On this last rebuild our mechanic contacted Banks about the trans command and they told him to wrap the exhaust pipe with insulation to keep some of the heat off of the module under there and that seemed to work some.
(It shifts better than at first except for going in and out). Another thing that might be interesting is when it was first rebuilt this last time it had a problem with jerky shifts and the tranny light would come on. Our mechanic had to replace some sort of sensor in the tranny that kept breaking. He did this about three times and since he wrapped the exhaust it hasn't happened again. I hope I made everything clear for everyone to understand.

I have a 91 pontiac Grand Prix with a 3.1 and the car has NO leaks, however, I have noticed that the transmission fluid level go down and the engine oil goes up. My conclusion is that some how the tranny fluid is crossing over to the engine, is this possible? and if it is, how or where?
NOTE: my car has a tranny cooling line to the radiator but no engine oil cooling lines and the colant is clean. how is it possible?

A while ago, I acquired a 1991 Mazda 626 automatic (currently 105,000 miles) that now has what appear to be the beginning of transmission issues. It hard shifts from 1st to 2nd - the shift jerks really hard when the car is cold but once I've driven it for 15-20 minutes the hard shift almost disappears completely and stays that way as long as the car is warm - except for stop and go traffic (Seattle traffic) than the hard shift comes back no matter how long I've been driving. The only other shifting issue I notice is on the hills where it seems to shift more frequently than I might expect it too.
Other than what I've described this car is in perfect condition inside and out, as well as engine-wise. My question is on transmissions and whether I should get a rebuilt one. I've taken it to multiple transmission shops and almost all have told me two things 1) I need a new transmission and 2) that the issue is a hard component problem and I could most likely drive this car for months or years without having to replace the transmission - if I want to put up with the rough shifts. They recommended just driving it until the transmission goes out and then replacing it.

I have a 1991 bronco with a 351w and the e4od trans.. The transmission is shifting late and hard and sometimes when i let off of the gas to slow down it shifts between gears up and down by itself... The only lights on the dash that are on is the Rear Anti-lock brake light and the speedometer is not working either.. Where to start the trouble shooting to fix it?

I am looking at buying a 91 f250 4x4 with a 5.0 and an e4od. When I start the truck I can feel It roll forward A little bit. I can put the trans In od or nuetral and It will drive and shift normally thru all 4 gears, no slipping and no noise no vibration, It shifts and acts perfectly normal. 1st and 2nd work fine as well. When I put it in reverse It rolls forward slightly then drops Into reverse, it will not actually back up, you can rev the engine to stall speed but no higher. Sometimes in park If you rev the engine It will actually over come the parking pawl and roll forward.
Also when In park I can rev the engine to stall speed only. It only starts in p or n, and the reverse lights come on in R so Im assuming the mlps is adjusted properly and the manual protion is adjusted properly. I pulled codes and had 3 in total, ect shorted, egr flow insufficient, and 1 code for torque convertor clutch solenoid I believe It was 632. Im assuming the reving up to stall speed Is related to the tc code. The fluid level Is fine but is a little dark In color, I tried doing a search with no luck ..

I have a 91 Celica that has a strange transmission problem. She hates the cold weather. No joke, she drives GREAT in the warm weather. But when its cold, she refuses to change into the highest gear until she feels like she's warmed up enough. But even then, she will randomly downshift again (all other things like speed, elevation, etc. constant.) When that happens, the RPMs (obviously) jump up. I always try to slow down when that happens, and eventually (5-7 minutes later) she shifts back into the appropriate gear.
I've owned it less than two years and have done A LOT of work on it. I am hoping to upgrade with a vehicle from a family member, and actually have the Celica for sale (and I hate selling cars......I don't think $1400 is too much for her!) Only 133,000 miles as she sat for a LONG time before I got her. I got all the kinks worked out except this transmission issue. Everyone I've talked to is stumped. And other than the "cold" issue, she shifts beautifully. I've been told to NOT flush or change the fluid at this point, so I haven't done that, but it's full.
I don't know if it's related, but the temperature gauge very rarely makes it off the 'C' mark. Sometimes when I'm idling it will climb to a whopping 15-20%, but generally it lives at or below the 'C.' I have never seen it at or above 50%.

The trans in my motor home has made a growling or slight grinding metallic noise after it shifts into 3rd gear. It only does it for maybe 3 seconds and it doesn't seem to affect the operation. Only way I can describe it is that it grinds, and shudders then goes away. I have towed my race car all this year and it has not caused any issues at all. I am planning on driving out west next year and would like to figure out what the deal is before I hit the road. Also if a rebuild was in order what improvements can be made during a rebuild?

I have a 91 Miata Auto. I bought it from someone that (I think!) never drain auto trans fluid during its 145K mile life. So last year I replaced all the gaskets/filters and tuned up the car. It runs fine except shifting harsh in cold weather. I have to mention that it seem to have no power and goes very slow on first few minutes.I used a pump to suck trans fluid out. It was so dark (even I dropped the trans pan and replaced filter/gasket). Then I pumped Lucas trans fix fluid in and it seem to improve. What should I do more to reduce the harsh shift condition in cold weather? Or is there a booster module need to be replaced?

I have a '91 Camry that's my daily 50 mile round trip commute car. It runs well and still has lots of pep at 156,000. There are oil and tranny leaks (tranny leaks around the pan seal) but I check the levels and keep everything topped off. Tranny fluid and filter were changed about 20K miles ago. I am the original owner. Shifting is OK unless I accelerate hard, then it "bumps" into gear. On hard acceleration it is a pretty good bump but if I back off the gas it shifts much better. There are no other symptoms, at lower speeds it shifts fine unless the A/C is on, then I get bumps above the 1-2 shift. What the problem is?

I've got a 2000 ranger w 158k miles, been having issues with a misfire over 65mph, and it's been throwing a check engine O2 sensor code. One of the probable reasons for the O2 code read low fuel pressure... so my husband got the bright idea of replacing the fuel pump.
That turned out to be a big story in and of itself. BUT we got it replaced with one that works, however.... now it won't start!!! You have to pump the gas and like crazy and hope that it'll start, it will eventually... but not without a bunch of coaching.
Once it's running, it's running ok. The first day after replacing the pump it was AWESOME, ran like it used to years ago, no misfire, smooth as could be, no rattle, no check engine light. But it all came back it's misfiring again, rattling when you accelerate, and the check engine is back on. I haven't had a chance to go run and get the codes ran again, maybe tomorrow I'll be able to do that in between errands. Oh, and we are gonna replace the fuel filter at some point in this week...

1991 4x4 f250 idi w e4od w 3:55 ratio... The truck is slow to engage in reverse, about 5-10 sec. It also has a very hard shift 1-2. All other shift points are good. Drop down is good, and TC lock up happens at all the right points (feels like anyway).
I've had the truck for about 2 years now, replaced several sensors an harnesses and a full fluid change to solve other problems but this still remains.
Sometimes when I start it in the morning if I let it sit and idle for a few min it will engage reverse much quicker AND shifts way smoother and constant. Shifts smoothly thro all gears, holding a constant 1800-2000 rpms with no drop or lug. Or do I need a rebuild?

I have a 2005 Prius Gen II with 114,000 miles on it. I was driving last week when it suddenly displayed a Christmas tree of lights that included VSC and the triangle of death....and of course the battery fan kicked into high gear.
Hooked it into a OBD II scanner:
P0A80 "Hybrid battery pack over temperature"
P3019 "battery block 7 becomes weak"
P3000 "DSL solenoid circut low"
P0300 "random misfire detected"
P000A "engine position system performance- bank 1"
Also C1241, C1242, c1249, c1259, c1310, c1357
I went ahead and cleared the codes. The angry lights went away but came back within minutes of driving. The car went into limp mode but I was able to make it home.
