Got stuck in the snow yesterday, I was rocking the old jeep to get it out and ran some high revs. Seems the transmission got hot. Did manage to get it out. However since then the transmission seems ever so slightly hesitant to go from 1st to 2nd. It somewhat jerks a hair while shifting. Once in high gear it does okay. Also was getting a low coolant indicator and did add some antifreeze today. Transmission fluid seems okay and fairly clear. It is an automatic. I thought about this for a bit. Isn't there a regulator of sorts on the side of the transmission that controls shifting of the lower gears? Anyone have an idea of what could be causing this? Burnt clutch plates?

Did your check engine light (CEL) come on, or are you getting any CEL codes?
Auto trannys are so complex it's hard to diagnose problems. But if it's something like a throttle position sensor, speed sensor or solenoid it will usually trip a CEL code. I know the 4-speed Ford auto that's in the early late 90s early 00s Rangers, are known for solenoids going bad, which causes the symptoms you describe.
If the check engine light isn't on, then it might be something more complicated and expensive.
My brother paid AAMCO thousands of dollars to replace the tranny in his Mazda MPV, (another Ford tranny) which they told him was toast. 1 month later it was having the same issues, after taking back in, and having it at the AAMCO for another week they were clueless. He finally took it to the dealer where in an hour they figured out it was a $50 part Mazda knew was prone to failure, in fact they had issued a service bulletin about it years earlier, but AAMCO was to stupid/lazy to check the service bulletins.
So they replaced it for <$200 after he'd paid AAMCO thousands to "fix" it. And no AAMCO did not refund him any money.
Moral of the story:
Always get a second, third and fourth opinion when it comes to major auto repairs.

Didn't check the CEL code but the engine light did not come on.

I dont know about your jeep but transmission fluid is generally cooled by being pumped through the bottom of the radiator, has the situation gotten better since topping up the coolant?

I thought this thread was going to be way different than it is. Im glad for my sake its about cars.

How hot is hot? Does the fluid smell burnt? If the fluid did get hot then the very least you should do is a fluid change, and since you have to drop the pan you might as well do a full transmission service. with the pan off you can also look for little pieces of the clutch pack and bands. If the fluid doesn't smell burnt then the problem probably lays somewhere else like a modulator, or servo. It may be something as simple as a vacuum leak.
Oh and wtf a automatic transmission in a jeep.
Just say no to slush boxes.

It's (gulp) 2 wheel drive and a straight 6. Only cost me $9,500 when it was only 3 years old and had a wholesale price of about $12,000 and a market price of $14,500. Gets good gas mileage and up until this year never got stuck. Best yet, it's paid off.

I'm just razzin ya.
I just hope you didn't hurt the trans none.

Same here, when I saw the first word I thought someones looking for Skuzzy's ban stick.

Take the pan off and change the filter. Alot of black crud in the fluid means you have some worn out plates. Check the vacuum hose for being off or leaking. My personal experience with jeeps is that the transmissions are not that great. :salute

take a wiff of the fluid. it should be red...very red if it's freshg, and dark reddish if it's not so new. smell some tranny fluid in a bottle, then smell the fluid on the stick. if it smells burnt, then you'll want to have it changed.
how long since the last time you changed it? if it's more than 30k miles, then change the fluid n filter.
i'm not much of a transmission guy, as i farm out most major tranny repairs.........but i think they did away with the external regulators years ago.
what do you mean by "jerks"? in my opinion, pretty much every jeep i've driven has a pretty firm 1-2 shift.
also...this just hit me....was it really deep snow? there is a throttle valve cable on these trannys......it could simply need a slight adjustment.
hope something in there helps ya......

Pretty deep, I'm going to have the mechanic take a peek. I know something isn't right.

Where's Widewing at?
He seems to know Jeeps as well as anyone on this board, maybe shoot him a PM.

YOU SAID it's a 90's jeep right?
if so, try this.
without starting the car........cycle the key from off to run 3 times...leave it in run the third time. now, count the flashes of the check engine light. there'll be long flashes, and short flashes. the long ones are the "10" and the short are the "1".
so, 3 long, followed by 2 short, would be code 32. if there's more than one code, they'll be seperated by an approx. 2 second space.
you more than likely will see a code 55 and a code 12. the sequence is ended when you see 55 for the 2nd time.
let me know what the codes(if any) are, and i'll look em up for ya.
