i am having problems shifting. it wont shift into reverse all the way and when its in drive it has a hard time shifting from first to second gear and wont shift into third.
View 1 RepliesI have a 1996 Silverado and it will not shift out of first gear. I have had the pickup for about 6 months and when I got it, it would shift if I accelerated to about 30 and let off but then I went though some mud and got stuck, I kept shifting from reverse to forward and I got out of the mud and it would not come out of first but reverse works fine and it will not shift manually at all the pickup has a 4l60e transmission.
View 5 RepliesI have a 98 Chevy truck with a 4L60E. It has no second gear. I was sitting in park for about 10 minutes with the engine running, then put it in drive and it never shifted into second. It felt like it went straight to 3rd. I played with it manually until I figured out I had reverse, 1st, 3rd, 4th and torque converter lockup, just no second gear. My acceleration rate was medium and when I reach about 27-28 mph it would shift from 1st into 3rd. It has 230K on it so I rebuilt it with all the typical parts - frictions, steels, band, sun shell etc., still no second. I then pulled the pan back off and replaced the spacer plate and put in a shift kit. While I had it down I put a corvette servo in and did an air check. It worked fine. I could feel the band tighten.
Both the 1-2 and 2-3 solenoids checked good at 23 ohms. I swapped their positions to see if it would make a difference. I also checked to make sure the 1-2 accumulator piston wasn't stuck in its bore, the spring was new from the shift kit. It was fine. Put it back together...still no second gear. When I originally pulled the pan off for the rebuild, the pan was free of any debris and was very clean. I then drove it a couple of miles to a local transmission shop. They put their scan tool on it and drove it around the block. There were no codes and the ECM was calling for second gear. It doesn't sound mechanical since almost all the parts have been replaced, rebuilt or inspected that affect the 1-2 shift. It sounds electrical. Is there anything I have missed?
97 Silverado - 5.7 with 4l60e trans. truck will not shift into 2nd gear while driving. stays in first gear until rpm are high and shifts into 3rd. under hard acceleration will stay in 1st until let off gas then shift into 3rd. manual shifting results in same, no 2nd gear until selector is moved into 3rd then shifts into 3rd. Haven't got any trans codes, fluid change netted no change in performance, fluid was pretty dirty but didn't smell burned, and there were no metal shavings in pan.
View 9 RepliesTruck has 222000 miles on it. With gentle acceleration not noticeable, with maybe half throttle rpms increase for say one second or two and then shifts smoothly into third, However at full throttle with the shift coming at 55 mph or so, it shifts perfectly with no slip. It also acts the same manually. I had asked my mechanic about changing the fluid and if it could fix the problem, he said, "well it could work or hurt it." After thinking about it, we decided to change the fluid. He did a full flush and cleaned out the pan which had lots of sludge in it but no pieces of metal in it that would seem to indicate a major internal problem. It doesn't seem to have made it much worse if at all, but did not fix it.

If I accelerate gently and keep the rpm down to about 2500 or less, I get a normal shift from 2 to 3 and I can then accelerate with vigor without any apparent problem.
If I accelerate the way I normally drive, at the 2 to 3 shift point the transmission misses the shift and I have to let off the throttle for a few seconds and wait for 3rd to engage. I usually see no codes, but once in a while P0758 reappears.
Both solenoids A and B have been replaced, as described in the thread referenced above.
More symptoms, and maybe this is a vital clue: the 3 to 4 shift is fine, but I've noticed that lockup takes a while to occur. When locked up, I normally see almost exactly 2000 rpm at 70 mph. I am seeing about 2150 rpm at 70 mph until lockup finally takes place, but I can't say exactly when it does happen---I have to watch the road now and again.
I understand there are a 3-2 solenoid and a pressure control solenoid, but I don't know enough about their purposes to decide that either needs to be replaced.
I have a 1994 C-1500 4.3L with a 4L60E transmission. After driving for 30-40 minutes it loses 1st gear and you have to manually shift between gears. R, 2, D and OD can be manually selected but there is no automatic up or down shifting. There isn't any gear slipping prior to this. After sitting for 25-30 minutes everything works fine. I have noticed that sometimes before the problem occurs that if i manually select 1st gear it will stay in 1st & sometimes it will automatically shift to 2nd even though the gear selector is in 1st. Also it usually shifts into D at about 30 mph but sometimes it stays in 2nd until I manually shift down to 2nd and back up to D. It isn't giving any relevant codes (use jumper & flash codes). I'm thinking possibly faulty solenoid(s), but not sure.
View 2 RepliesMy car is taking a long time shifting from reverse to drive in the morning. Do you know what may be causing it and how to fix it. It's a 1995 automatic ford explorer.
View 3 RepliesI recently purchased a 09 Silverado with 73,000K and have periodically noticed a faint Antifreeze smell outside the vehicle near the engine when I park it in the garage. I cannot find any leaks and have not added any coolant. It does not smell inside the truck. Could a pinhole leak do this and not easily show up? Any way to test for this.
View 2 RepliesI have a 2000 Silverado 2500 HD, 6 liter engine. The transmission warning gauge has been showing it's overheating. I changed the filter and fluid and the gauge still shows red warning.
View 2 RepliesI have a 1995, 1500, 350eng, PU. there seems to be an electrical problem in the ignition system. when the key is turned on the check engine and other lights do not come on and there is no power to the coil/ignition. When the lights do come on the truck starts. I have replaced module, dist,pickup coil, coil, cap and rotor. Could the problem be in the computer?
View 1 RepliesI have a 1995 Chevy Silverado 1500 Ext. Cab Z71 4x4 that I've had since '97. Last year it started over-heating, the temperature stays exactly where it is supposed to when I'm running down the highway, but starts to over-heat when I slow down to make a turn (up to about 230), but cools back down at an idle. The Truck has a standard 5.7L TBI 350
Trying to remedy this problem I've changed the thermostat 4 times (with a 160, 180, and 195), changed the radiator, changed the map sensor (thinking that it might be leaning the fuel out to much), changed both temperature sensors, replaced the water pump 3 times (the 3rd time I ordered a Flowcooler waterpump from Summit), changed the instrument cluster and computer thinking it might be electrical, replaced the catalytic converter (thinking it might be restricted), I even replaced every hose on the motor, I then installed a brand-new GM 5.7L 350 crate engine but it did the same thing.
After installing the new engine I replaced the knock sensor, the O2 sensor, changed the throttle body (with one from another motor i had for my son's '94), replaced the distributor, replaced the injectors, checked and made sure there wasn't and blockage in the center intake, cut the exhaust at the catalytic converter just to make sure there was no restrictions.
I recently tried a manual temp gauge just to see if the motor was actually getting hot, which it is.
I have a 1995 Silverado Diesel 4X4 with 145K miles. I only drive about once a week to take trash to the dump. It's been running great until yesterday. I put in drive and went to pull out of my drive way and truck won't move. It makes a terrible sound in the rear of the truck but won't budge. I have checked transmission fluid level and appears to be good. I say appears because my drive way is on a steep incline and it's backed in, bed on the down side of hill.
View 5 RepliesI have a 95 chevy silverado. 305 with an automatic transmission. I was driving down the street at about 30mph when the power went out on me.
The engine stayed on and all lights stayed on. I could rev the engine but the truck wouldn't move.
I then had a friend tow to my house and i let it sit overnight trying to decide what to do next.
The next day I went out and started it and it and was able to drive it again for a short distance at low speed and then it did the same thing again.
I have a 1995 Chevy C1500 Silverado. The blower and heater work great when I start driving. After about 20 minutes of driving on high blower speed, the strength of air blowing out reduces drastically and eventually no air is blowing out of the vents. I can still hear that the blower is blowing air, but there is no air coming out of the vent. The Midas repair shop I frequent couldn't reproduce the issue on their short test drive (of course). They told me to bring it back to them whenever the problem occurs. I haven't had the opportunity because by the time I get out of work, they are closed and I am freezing to death every morning.
View 1 RepliesI have a 1995 Chevy k1500 Silverado Z71, I am having problems with my tail lights where when my headlights are on and I hit the breaks the driver side tail light completely turns off, if I use the left blinker it blinks very fast up till I hit the breaks. When my headlights are off they still don't work properly but legal enough, the left blinker blinks in between fast and slow and when I use the brakes the left side works but very dim, the wiring is all original never tampered with, all I did was put aftermarket tail light covers on it which shouldn't affect anything. The problem usually comes and goes but this last time it lasted for 2 months and now everything works perfect, the problem will be back and I'm afraid I'll run out of luck and a cop will finally notice it.

View 8 RepliesToday my driver side seat belt got locked in the retracted position for no reason. I drove the truck to work, no issues with the seat belt, but when I got in to go get some lunch, I went to put the belt on and it moves about 2-3 inches out of the retractor and locks.
The other issue I'm having, is that I can't get the retractor cover off to see if theres something inside locking the belt or if it is going to need to be replaced.
How to get the cover off and if possible, fix the belt without replacing it.

View 6 RepliesI have a 95 Impreza with the 1.8 motor, this thing is hesitating when you give it too much gas at once. I got the car this way so I don't know when it started. I put in new plugs, the wires tested ok, and the ignition coil tested ok too. The only code the engine was throwing was 21 the coolant temp sensor and that has been replaced. I also put in new o2 sensor, maf sensor has been cleaned. Checked for vacuum leaks and there are no leaks, also did a compression test and got 180 on all 4. Where to look next, I don't want to just replace sensors without knowing what is wrong. The car did run better with the tps sensor unplugged but still running very bad.
View 2 RepliesI have a 1993 Chevy Silverado, 350, 2WD. It has a 4L60E transmission. I just started having a problem shifting from 1st to 2nd. When accelerating the RPM's go way up and won't shift until I let off the throttle. Then it shifts into all other gears normally.
If I accelerate slowly. it will shift into 2nd at about 16 MPH. It will then shift into all other gears normally. I have replaced the Throttle Position Sensor, flushed the transmission and replaced the filter and fluid. This made know change in performance.
I am now suspecting that it might be the 1-2 shift solenoid. The check engine light is not on and everything else works fine.
