Transmission doing strange things.

I put up a question the other day but I now have more info. I put the jeep in drive the trans will slip but still stay at 2000 rpms. It still moves but poorly then it will catch and be ok. But if I put it in 1st by moving the automatic gear selector it does not slip at all. The trans is in fair shape. If anyone knows what is causing this or what to replace to fix this Please let me know.

What year? By what you are saying in this post it may be your linkage being off a bit and not being fully in drive.

2000 wrangler. I just took it out and played with it. I realized its not slipping when in drive its starting in 2nd gear. It just strugles to get going because of being in higher gear. It won't go into 1st unless manually shifted.

if its in limp mode it will start out and stay in second gear. is the check engine light on? even if its not i'd have it scanned for codes, could be as simple as a relay, or i've had some chrysler speed input sensors go bad.

It is in limp mode for sure!!! What does the fluid look like???Is it low,high,burnt,dark colored or have water in it???? Any of those can send the trans into limp mode.Mine would also shift fine by hand but not on its own when I got water in it.It finally went out even after flushing with a new filter and fluid then $120 worth of ATF through the trans flush machine.

I don't have any codes. I changed the fluid and filter yesterday. What will I have to do to correct this? Just flush the trans again? Is there anything else that will cause it besides dirty fluid? Is there a way to manually take it out of limp mode?

limp mode is a mode set by the computer, it simply means the transmission only uses 2nd gear or reverse. its usually an electrical/computerized problem ie: sensor, relay, ground etc. there is no way just to take it out of limp mode, its in that mode for a reason, cuz somethings wrong and its trying to protect itself, and yet allow the driver to "limp" to wherever it has to go to get fixed. i've never seen it but i suppose water in the fluid could cause it. usually when that happens the transmission doesn't wanna shift or work at all, not just limp mode.

if you just changed the filter and fliud, and now its doing it, check what you did. i've seen a couple trans filters not installed properly, and they have come off in the pan, or loose and caused bad trans problems.

It was doing it when I bought the jeep. I tried the fluid to see if it would help. I guess I'll call the tranny shop and see how they want to rape me.

Yeah I know but she did not want to leave me stranded 40 miles from home in the back woods.Actually that day it only stayed in limp mode for around 8 miles and then finally shifted but then the shift pattern was way off and then came the slippage about a month later.Before the slippage some times it would not shift all the way down to first at stops but other times would shift and pull fine.It was a valve body or pump issue I think.

I just know how tranny shops work! Oh it will only be like 600.00 at the most then you go to pick it up its 1200. Then your likd I could have got a new tranny for that. Then you feel like a 2 dollar hooker on half off night. Its all bad.

the 32rh has no limp mode, if you did the fluid and filter change and its still bad it could be a the valve body. what ATF are you using?

if it doesn't have a limp mode, which most newer vehicles do which is why i assume it does, then it is a mechanical problem. i'd make sure there is no limp mode, chrysler vehicles are notorious for limp mode transmission problems. if its not in limp mode its got internal mechanical problems, as long as the fluid and filter are good.

be very careful of rebuilt trans's. there are so many rebuilders out there now, and the quality really sucks. i stick with local reputable rebuilders, i wouldn't use an internet supplier or anything like that.

i would rather install a used lower mile factory unit that a reman most of the time.

I wish I could find someplace to sell me a brand new tranny. Then I'd put that in and try to rebuild mine myself. I am a mechanic but don't have much experiance with automatic transmission. But if I could buy a new one I would love to learn on my own. I can pick up stuff just from reading so I would buy a guide and have at it. Then I'd have a spare.

then buy a used one, thats your best bet. i've had a few auto trannies apart, there's a lot of parts, but with the right info you should be able to figure it out.

another reason i like manual trans, so much simpler to disassemble and repair.

It does have the limp mode feature! Also if you are not using fluid that states ATF+4 or equivalent in it that may be your problem.If you want a spare tranny I would try Davey's Jeeps D A V E Y S J E E P S . C O M - Specializing in Jeeps & Jeep Parts

I cleaned the pan and I found a retaining ring in it. I guess theres no hope now. Need to rebuild or replace. New transmissions are outragous. So I guess I'll get mine rebuilt. I found another forum where a guy had the same thing and had a retaining ring in his pan. He said he paid 598 for everything. I might have to join that forum so I can ask him where he had it fixed at. Hes from IL too.

limp mode is controlled by the computer, its not an internal trans function.

just did some quick reading at work, it doesn't sound like that trans is computer controlled hardly at all. the pcm controlls converter lock up, and a couple sensors are involved, but it is still pretty mechanical. i still could see the pcm using a limp mode if a relay or sensor is bad. but obviously that doesn't sound like the case here.

I am having a similar problem right now actually. I have a 2000 sport with the 32rh tranny and mine will not go above second gear. if I have it in drive, it will switch to third (i believe) but nothing catches, My rpms just go through the roof, so I had to keep it in drive 2 to make it home, I am trying to figure out if I should find another tranny, or actually if it is better to switch to manual if not too difficult.

I am taking the jeep to the tranny shop tomorrow. I found a place in Indiana that will take it out rebuild it and put it back in with warrenty for 500.00 plus tax. Thats a great deal. They said it should only take 5 days at the most. I'll miss my jeep for 5 days but that will save me a big head ache. Can't even get a rebuilt off the net that cheap. Its an hour drive but its worth it.

does anyone know if you can use the A999 tranny in replace of the 32rh. It is supposedly the same trans which was renamed in 1992. My concerns are if the torque converter will be balanced the same (internal or external) and the bell housing. Anyone try this before?
