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?
Ford Transmission :: 1999 - No Forward Or Reverse Gears / Black Trans Fluid
My 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...
Trans Sport :: 3t40 - Trans Slips When In Reverse Under Load?
If I press the gas a little hard in drive, my tires squeal but if I'm in reverse I can feel a slipping in the trans. If I try to back a trailer up an inclined driveway, it won't go, the trans slips. I have no crud in the pan. I've replaced the reverse boost valve. I installed a Trans-Go kit which is suppose to eliminate the reverse slip but it hasn't worked. Everything else works just fine and my fluid is red. I have engine braking in 2nd and 1st. The van backs up fine, it just does this in reverse under load.

I was driving out of a parking lot and as I accelerated onto the main road my vehicle stopped. I heard a grinding sound and could not go forward or reverse. While the car is in drive, park or reverse my car will roll any which way. It pushed it across the street. I tried to locate my tranny dipstick via visual inspection and manual. I could not find it. Could the stick have never been put back at some point in service and caused this issue. That seems unlikely but the thought occurred. Could it be the velocity joint? Whatever it is it certainly sounds like a transmission issue.
View 1 RepliesTrans 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.
Golf IV / Jetta IV :: 2003 With Auto Trans - No Forward Or Reverse
2003 jetta wagon 1.8t 106000miles with the tiptronic auto trans, has no forward or reverse, no codes, have already drained fluid and refilled, i can see the rpm gauge move when i shift from park to R to D etc, but it will not go at all, i'm thinking maybe the toque converter has failed.
View 6 RepliesAccent LC (2000-05) :: Auto Trans Went Out / No Reverse And The Only Forward Gear Is First
I've got a 2003 Accent and my automatic transmission went out, no reverse and the only forward gear is 1st. Was thinking of pulling it and swapping it for a used, but I have been reading on here the many, many automatic transmission problems of the accent and my next thought was to just rebuild it myself. But now I'm thinking more along the of a swap from auto to manual, as I don't want to have to rebuild a transmission that is only going to have to be rebuilt again anyway. As far as stuff like the clutch pedal, linkages, gear shifter, I can get those pretty easily. Does the Accent have a hydraulic clutch?
View 2 RepliesTrans 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.

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 RepliesFerrari :: Transmission Would Crunch When Engaging Reverse
In today's show, a caller with a Ferrari noted that sometimes the transmission would crunch when engaging reverse. I've never had the pleasure of driving a Ferrari, but two Porsches I owned (in my single days) had similar issues. There is no synchro for reverse gear.(Ferarri may be the same) So if I idled in neutral to get the gears moving and then shifted to reverse quickly, the gears would crunch as they meshed. A little drag from the clutch not disengaging completely or the pilot bearing dragging would make it worse. Two solutions are
1)let the transmission coast down by holding the clutch in for a few seconds before engaging reverse, or
2) shift to second, then straight to reverse.
Ford Transmission :: 2006 - 4R75E Trans Slips In Forward Gears?
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?

I 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.
Ford Transmission :: 4R100 Grinding - Now No Forward / Reverse?
A friend just bought a 99 Navigator, with what wikipedia says is the 4R100. Previous owner allegedly rebuilt the trans but used the old converter
It was apparently slipping a bit, or something, when he got it. Then on the way to my place so I can drive it and see what I think, it started making nasty grinding noises once he hit 4th gear. He got off the highway and made it to my place just fine.
Put it reverse to turn around in my driveway and it started the grinding noises again. Forward gears initially had some grinding as well after that, with no forward motion. Now there's no grinding, and the engine free revs in any forward/reverse gear
Fluid is full, still red, but smells nasty.
I don't suppose the three feed bolts above the valve body being loose would cause this? I imagine he's looking at a rebuild, which neither of us really want to do.
Ford Transmission :: 4r100 Will Now Go Into Forward Gear But No Reverse
Early 2000 F250
Originally the truck would not go into any forward gear, but had reverse all day long. So I had a rebuild kit ordered (new bushings, seals, frictions, steels, a washer and flat bearing kit, a sprak kit, and the od piston)
After rebuilding it, taking my sweet time double checking everything, it will now go into forward gear but not reverse. So I dropped the pan. The small 3 bolt plate was torqued to spec. When I got to the third bolt in the smaller section of the valve body (upper valve body) I heard a click like maybe a valve returned to its place but I'm not sure. I removed the valve body and accumulator and all the valves were free and had tension. When I had it apart the first time one valve stuck for a split second but I never could get it to stick again.
Finding nothing there I uninstalled the tranny and took the barrel apart all the way down to the L/R piston and could not find anything wrong.
After the build and me running the truck for about 10-20 min there was metal on the magnet (part of the reason I took it all back apart) however I could not find anything worn or chewed up. Could have been the tc I prefilled with 2 quarts in stead of filling all the way.
When I initially rebuilt the 4r100 I took apart the pump to replace the bushing and seal but did not take apart the valves. I've heard the pump is directly related to reverse but I'm not sure. Could something gone wrong in the pump when I took it apart? How would I know? If I new all parts of the reverse system I could then test them.
Golf/GTI VI :: Knocking Sound Both In Forward And Reverse
I have a strange knocking sound coming from one of the front wheel wells It sounds like a CV joint going out, but only knocks when the suspension goes up and down. I noticed it after about a week after I installed some H&R sport springs. Its not very loud and is not continuous knocking like a CV joint would be... It does it both in forward and reverse. The H&R sport springs make the car look better and it drives great otherwise.

My '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.

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.
