2003 Explorer with a slipping transmission...codes are P0731, P0732, P0733... Just had a new solenoid pack installed last week when O/D light came on and truck was clunking into reverse. Now, after new pack was installed the forward gears are slipping all over the place!
View 5 RepliesFrom the other users it seems that almost all are having slipping of gears and rough shifting associated with this code. On mine I'm not getting any slipping or rough shifting...it actually still seems to be driving just fine. The OD light came on and will go away after shutting the truck off and back on...it will then not flash anymore for say a couple of months or so...this has been happening for the past few years every now and again and i never thought much of it. I just made a 2k mile trip and this happened again but this time it threw the p0775 code which is a first.. Is it possibly a very early sign of the sensors going bad.
View 3 RepliesThe truck is a 2002 f150 4x4 5.4l... I was driving down the free way last night in 2wd doing about 90kpm when there was a loud bang like a ran over something. Speedo went to zero and abs light came on. Pulled over and shut it down. Crawled underneath to check so damage and couldn't see anything. Stared it back up put it in drive and it just revs. No forward gears or reverse. Fluid level is good, bright pink. Dropped the transmission pan, pan is clean and magnet has next to nothing on it.
View 14 RepliesI have a F150, 2nd 4.6, 122,000 miles. No forward gears. When put in drive, you can feel it trying to engage, but doesn't engage completely. Reverse is a solid engagement. Replaced filter and fluid, same issue.
View 12 Replies2003 rav4 . Recently, my rav4 has been slipping from gears 2-3. After exhaustive research, I found out that my car is known to have a bad ecm. So I decided to get a fixed ecm and replace it in my car. Car still slips so, thinking the ecm is good, I had my transmission rebuilt. After rebuilding my transmission, it still slips from gears 2-3. Do I need to replace my ecm again to coincide with the new transmission? I'm completely at a lost.
View 12 RepliesI have a 96 explorer (Eddie Bower Edition) with automatic trans ( not sure which one at this moment)....
Today getting on the freeway as I was getting up to speed I heard what sounded like a click then no longer had any forward gears. After rolling to a stop I tried every gear and nothing I did fell like it wanted to go but it would not move.
The trans fluid did not smell burnt and at most I might have been maybe 1/2 quart low. Where to start and what to check?
I have an automatic Jetta and just hit 130,000 miles. Recently, my car would randomly after I turn it on and put it in drive, the car would jerk forward and make like a popping noise. Then the car drives fine as usual. As if the gears are slipping? Is this a sign that my transmission is going out? What else can cause this? What should I do?
View 2 RepliesI have a 98 expedition with a 4.2 liter 4x4 and what I believe to be a 4r70w transmission (u code on the door sticker)
The original transmission went at 105k miles and was replaced with a new factory ford transmission by a ford dealer 3.5 years ago. The new transmission only has 10k miles on it.
Now the new transmission only has reverse. reverse works like normal but no forward gears. the idle will change when i put if in gear, but will not move, acts like it is in N . There is no strange noises.
It's hard to believe a new trany is shot already, no towing, or off road use.
My question is : is there ANYTHING that can go bad that would cause this? The trany fluid is clean and clear bright red, and no burnt smell.
I want to check everything I can before calling a tow truck to have it looked at. I will have it repaired if needed, but I don't think I want to replace another tranny.
Had tranny fluid and filter replaced a couple months ago. It's in a 35 foot motorhome (F53 chassis). The motorhome is within it's GCWR. Climbing a 6% grade at 3,500 rpm, little more than half throttle, like all the other climbs. 80 degrees out. Engine temp was on the letter "R" on the word "NORMAL". All of a sudden my engine redlines as if it popped into neutral. I let off, put it into neutral, and try "D" again. Nothing.
At this point it's uphill so it's naturally slowing down and I try "2". Nothing. Even slower and I try "1". Nothing. Pulling over blocking the right lane on a blind curve on a grade is scary. Had pylon cones out, waving traffic to warn them down a ways, etc.
No fluid on the ground, no slipping prior to this. I have reverse. I see no obvious linkage or electrical/wire issues underneath (from road debris, etc). It's at a shop but I want to know all I can so if they come back with something outrageous I can make a decision. I never pulled the stick, as I was coordinating traffic, highway patrol, a tow truck, etc.
I have a 1997 Mercury Mountaineer with a 4R70W trans behind a 5.0 liter. Vehicle sat for about 5 months. Went out to put it back on the road, and now the trans seems to be stuck in a forward gear no matter what the selector is in, park, reverse, neutral. Dropped the pan and replaced the filter and replaced what fluid was drained. no difference,.
View 3 RepliesI 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 1999 F-250 4X4 7.3 lit Diesel engine. My problem is my transmission will go into reverse great no problem but it won't go forward. I have no problem rebuilding the transmission if that's what it needs, I just want to make sure there isn't a electrical issue from the PCM first?
View 14 RepliesI recently bought a decent looking 1999 f250 4x4 5.4 auto. It has no forward gears and will only move in reverse. I topped off the fluids and have found no leaks so far the cooler lines are crusty but dry. I am gonna need to swap this thing out or do some more trouble shooting if there may be a non rebuild issue to solve.
View 4 Replies2006 f150 4x4 4R75E trans slipping in forward gears, reverse is ok. I dropped pan and it was clean. I dropped valve body and found OD servo shaft clip broken, the large snapring was I fine and in place. It allowed the inner shaft to float up and down. Would this cause my forward gears to slip or do I have a bigger problem?
View 14 RepliesI have a 95 F250 with 7.5 and E4OD. I was towing my Jeep and trailer out for the weekend a few months back (its been parked since) and heard some noise coming from the trailer. So at a stop light I put it in park with the engine running for a second, went to put it back into drive and it hasn't gone back into drive since. Reverse works perfectly. Fortunately I was able to back up onto the center divide, unload my Jeep and back the truck onto the trailer and tow home with my buddies Chevy. Anyways, its been dead since. Where I can start to look? None of the forward gears work at all.
View 13 RepliesThe other day I was leaving my house. I started the car and heard a quick, loud chirp. That was the only noise it made so I continued to leave. I rolled out of my driveway and proceeded to put it in drive and found myself rolling backwards. I tried every forward shift, kicked on the 4x4 and continued to roll backwards. I thought reverse worked but found that it wasn't engaging either. My question: is there anything I can look at before resorting to taking it to the tranny shop? I'm in school for automotive and am confident in my abilities to test solenoids and maybe even dropping the valve body to check that. Other than that, I lack the skill to pull the tranny myself and work on it.
View 3 RepliesMy 1999 7.3l Disel 4x4 transmission quit on me the other day. No forward or reverse. Got towed to my regular repair shop, and they are treating the transmission as a black box and recommending total replacement. The diagnostics they performed were to make sure it was shifting, and that indeed it wasn't going forward or reverse. They drained the fluid and said "it's pitch black" and said it had to be completely replaced.
Fluid level was OK, and it wasn't hot. I was driving along, and merging onto the highway. It downshifted, shuddred, and nadda. Free rev. I coasted to the next exit and into a parking lot. Verified that it was shifting, checked Rev and all forwards. It wouldn't shift into 4W, and 1-2 also wouldn't move.
I'm trying to figure out what might have happened... and if it's worth trying to have the truck towed to a transmission shop and have them diagnose and rebuild, vs just getting a remanufactured transmission. None of the local wreckers have any used transmissions, and the cost between a reman and a used is pretty negligible...
Not sure what the symptoms points to for exact failure mode, be it the torque converter, pump, input shaft, etc... I've never had an automatic transmission apart before, but built plenty of motors and am a machinist by trade. My preference is to try and root cause the failure...
I own a 2005 f-250 superduty with the 6L diesel. Just recently when I leave to work in the morning I notice the trans shifts slow through the gears and when it does start to shift it will start slipping then kinda vibrate for a few seconds then finally shifts into the next gear. It will do this through all the gears until I get up to speed on the highway. After it warms up it shifts and drives great until I let it sit for around 8hrs or more. I really hope I don't need a new Transmission considering I bought this truck as is from the dealership just a little over a month ago. I have checked the trans fluid it is full, I even drained all the fluid and replace with new and it still does the same thing.
View 4 RepliesTransmission on 04 V8 phaeton is slipping between first & second gears. transmission repair $4-10K. thought of just taking out the first gear via reprogramming (had a jag where you could do that for snow/ice conditions). do yo think taking out the first gear will cause extra wear & tear on the drive train? The first gear seems to be very short.
View 16 RepliesThe 91 bonneville stopped having forward gears but was drove back in reverse about 4 miles, reverse appears to work fine does this thing need new transmission or is there an easier fix...
View 7 RepliesMy '87 Chevy S-10 transmission slips like mad in forward gears and I can't go everywhere in reverse. The truck is gaaged in southern Virginia about 60 miles from my home and is used on some country property. The local transmission shop wants $1600 to rebuild the trans. He says he used sturdier parts than the replacement GM parts. I'd like to fix the truck because it comes in handy and was my dad's old mode of transportation around the Va. countryside, so it has sentimental value.
