Trans Sport :: 3T40 Automatic Transmission Suddenly Won't Engage Drive Or Reverse
This transmission shifted smooth and strong through all gears until today when it stopped all of a sudden to engage either Drive or Reverse. No previous signs of slippage, hesitation, stalling or lack of power whatsoever.
We checked the linkage to the transmission and it works as intended, nothing loose or broken, everything is in place. If there was something slightly different with it from other similar vans we have then it had a slightly delayed engagement in Drive (it took a second to engage it after you moved the lever) - on all other vans we have the transmission go into Drive almost instantly.
Van is a '92 Pontiac Trans Sport/Chevrolet Lumina APV with the 3.1L V6 Chevy TBI engine with the 3T40 automatic transaxle. Where we should start tackling this issue?
Trans Sport :: 95 TS 3.8L Misfire When Reverse Is Applied
My 95 TS 3.8L is misfiring on #4cyl ONLY when reverse is applied. When car is in reverse with parking brake applied, consistently misfires on #4. In drive with brake applied and engine load no miss. Neutral no miss.
Car drive ability is great in drive no misfires. 100% misfires on #4 only when in reverse. Is there any vacuum change or assist utilized with this trans? Possibly vacuum leak? I do not have a vacuum gauge. I changed to a different plug wire and same problem. New plugs installed. Have not swapped coils yet.
I am not familiar with this trans, other than the vacuum servo for upshifting I replaced when it was sucking up trans fluid like my old Powerglide in the OLD days.
Trans Sport :: Sound When Engaging Transmission / Forward And Specially Reverse
Just recently, my '93 transport 3800 has started making weird sounds when engaging transmission , forward...and specially reverse. This is not a transmission problem. It sounds like there is increased torsional movement of the engine/transmission unit and it made me take a look at the engine while would shift in drive and reverse....it does lean much..impressive ..but in fact I do not remember having tried looking for that before...so I cannot compare.

2001 VR6 owner. I'm looking at a Jetta currently that I suspect has a trans problem. Current Owner was bounced around shops being told it was a timing chain issue causing it to rev around 50-55 mph. Now I know that is definitely not it.
View 3 RepliesSilverado :: 2003 4L60e Trans Slips When Upshift 2nd To 3rd?
Truck 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.

I just picked up a 2000 v6 passat with an automatic trans. I am new to passats, esp with autos. The cars transmission is having problems shifting with the trans gets hot (25-30 min run time) and slips. What is the trans code for this car and is it FWD or AWD? It has 220k, and the engine runs great. It was sorta an impulse buy, I plan on flipping it so hopefully tis a good investment. Any common things I should be aware of so I can get it tip top shape to sell it?
View 3 RepliesFord - Explorer :: 2004 - Trans Slips In Between Second And Third Gear
My wifes 04 explorer 4.0 4x4 slips in between second and third gear and you cannot manually shift the gearshift below 3rd gear. I assumed tranny was going out but was told that it could be the transmission control solenoid or the transmission control switch (i think they are the same thing). I read that the most common symptom of this going bad is a slip between second and third gear. Haven't checked codes but will when i get home to see what it comes up with. This is the messed up model where you have to add fluid underneath through the drain plug. Was going to change fluid and add lucas to it to see if it remedies the problem.

My Haynes manual indicates that the ELC exhausts air when the key is off. Is it intended to exhaust all air from the shocks every time I stop? It doesn't make sense to lower the vehicle every time I stop for fuel etc. With over 200k miles on this can it's amazing that the compressor still works.

I am working on my daughter's TS, it has been overheating. Water pump is fine and the thermostat is working fine also. I did notice that the temp gauge on the dash isn't. I have noticed that the fan isn't coming on either. I don't have a book on this car or a owners manual. So I am unsure of which fuses to check. I did try turning on the AC to MAX to see if that would start a fan, and that didn't work either.

I have a 2002 Elantra GLS with the 4 speed auto and in the mornings or after sitting in lot at work for 9 hours, the trans shifts hard from second to third (almost as if it has a shift kit) and slips a little from third to fourth. The TPS was changed once and that seemed to eliminate problems at the 26K mark. I have 109K on it now and at around 80k took it in to the dealer with the receipt for the same complaint and what was done the first time. Dealer kept overnight and said there were no problems. I do know from having a performance TH350 built that the harder a trans shifts (up to a point) the longer it will last due to less friction on clutches and bands.

2006 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 RepliesTrans Sport :: 1994 - Oil Puddle Underneath The Car
I replaced my '94 TS intake plenum and upper and lower intake gaskets last year, and as part of the procedure I replaced the badly-degraded rubber gaskets that go at both ends of the manifold (at both ends of the "V", one under the throttle body, one under the PCV valve or so).
A little more than one month ago I realized the oil puddle underneath the car contained -besides power steering fluid from a known leak- motor oil. When I investigated the origin of the leak, I discovered the <> rubber gaskets have disintegrated AGAIN.
I don't see how this gaskets could be installed incorrectly, so I have to conclude the gaskets that came with the kit I used (Felpro?) did not withstand the oil as they should. Either way, I need to replace those <> pieces of rubber again
Now: since I don't want to be doing the same thing every 5 k miles, any good brand for these gaskets? Is there a material (neoprene?) that would last longer in contact with the oil?
Trans Sport :: No More Front Ventilation When Engine Is Hot
These super-hot days our TS had started to develop a very strange problem:
- when you first start the engine the A/C works normally and cold air blows from the front vents on A/C or MAX as usual
- if we shut-down the engine and try to engage A/C or MAX again the cold air would only come-out through the top (windshield) and low vents - no more front ventilation
- all solenoids appear to be working (moving)
Trans Sport :: CEL Started Come On Then Shut Off - EGR Fault
Just recently the CEL started acting...first, would come ON then after some time would shut off....but now it is ON and stable. I was almost sure it had to do with EGR....checked codes and indeed, 55 , large EGR port failure and, accordingly, 56, QUAD driver faulty voltage...obviously because of large EGR port solenoid control. I have not verified the EGR coils yet....will come back later as I'm going out for 2 days.... This is a rather new EGR valve...6 or 7 year old.....and in fact, no more than 25000 miles...probably less...
View 8 RepliesTrans Sport :: 1995 TS 3.8 - Slow Cranking When Hot
Our 95 TS 3.8 runs hot. I dislike the 195 Thermostat, but winter is coming. Temps can soar to 230 on gauge, with no air.(Now I remember why I had a 180degree thermostat).
I recently replaced a rebuilt delco starter that was about a year old.(faulty solenoid). I cannot recall if the Slow crank problem was there prior. When 230 degrees, intermittently I get a slow crank with dimming of dashboard lights, but bright headlights.
1. I know that the temps are supposed to swing a lot with this vehicle, but 75 degree days, 230 degrees when in heavy traffic is pushing it.(gauge). Is this normal for 195 thermostat?
2. Possible bad windings on new rebuilt starter? Armature drawing excessive amps when hot? Battery cables look okay, but original.
3. Considering a NEW starter and a heat reflector wrap for starter. New battery cables-thicker cable if possible(used welding cable for my old 421S.D.
Trans Sport :: 1992 / 3.1L Started Quitting While Driving
My 92 transport 3.1L had started quitting on me while driving. After sitting for about 15mins I could get it started and then continue on driving. Now its doing it more and I can't take the chance of going anywhere in it.
Got a CEL so I flashed codes 34, and 45. Where to start troubleshooting with what these codes are saying that I should do?
Trans Sport :: 1994 TP 3.8 - Overheating In 2 Minutes From Cold
I've replaced the drain plug, filled up the radiator with proper coolant/antifreeze, turned on the engine then closed the cap to see the needle going fast to near the red mark. I turned off the engine and touched the cap with my finger but it was cold so I did the same with a hose, not hot.
Well, it seems the problem was not all circuit was filled. I did add more after a while running and now it is working normally (knock wood).
Trans Sport :: 3.1L V6 - Misfires / Hesitation And Lack Of Power When Hot
Here is one of the nicest-running van we ever had with a 3.1L V6 TBI Chevrolet engine that always ran too good to be true.
Few days ago it developed a misfire condition that is very pronounced when the engine is hot/at operating temperature - under load it hesitates like it's running in 4 cylinders out of 6. When cold it starts right away and runs good & smooth.
Now the van can't go anywhere - it misfires so severely that the engine stalls and dies at idle.
What we tried so far, to no effect, was:
- changing the spark plugs & wires
- replace the distributor cap & rotor
- replaced the EGR valve
- replaced the IAC valve
- replaced the MAP sensor
We had a lot of 3.1L Chevy TBI engines and none ran so smooth like this one and, all of a sudden, none ran that bad in such a short time...
Trans Sport :: Slow Transmission Response Before First Engagement
From time to time, the first time the car is started in a day, the transmission (4T60E, 1993) may take several ............ seconds before first engagement, either in forward or reverse. Fluid level OK, color OK, filter changed 2/3 years ago. This began just a few months ago. After that, everything will work flawlessly for all the day , no problem at all, all shifts OK, all subsequent starts OK.
