Is the aw4 a good transmission. I have one that was rebuilt by speedy transmissions in knoxville tn not even 15k ago and its slipping already. Has anyone else had problems with this trans?

That's not normal! These are 300k transmissions when they're treated right... you definitely need to go back to that shop. Is it still under warranty?

STEPHEN_XJ_

The warranty is 12k miles or 12 months its been a year and its got 15k on it now

Jmb94

Facepalm. It should last way longer than that.. I would start crusing junk yards for one with under 200k and start with fresh fluid... do you tow a lot?

STEPHEN_XJ_

I don't tow any lol I just it to trail ride and my daily driver

Jeepjunky

well that sucks, im getting one that i have lying around rebuilt right now, when the motor gets built it will be thrown in with it

The Blacksmith

I suspect they didnt do a good job,

Do you run a cooler? not thru the radiator (cooling the trans thru the rad is stupid, because you will be keeping the oil over 200 degrees minimum)

STEPHEN_XJ_

No its all stock but thats a good idea. how hard is it to add the trans cooler, where did you get one and where did you mount it?

Jeepjunky

you can grab a trans cooler off any pick up in a junk yard and use it, or else jegs or summit have them pretty cheap, most people mount them in front of the radiator

STEPHEN_XJ_

do you just run the line that would go into the rad to the trans cooler and plug the rad or what....im new to jeeps lol

Did you check the fluid level? Low fluid will cause slipping.... Don't buy a new tranny without at least checking the little things.

I cut the steel lines and run rubber to to cooler. You have to use hose that can handle trans fluid. Also you can empty a quart and add a quart of lucuis I can't spell it but it works vary well. Dose take a long time to get it in.. Its like maple sirup.

STEPHEN_XJ_

i checked the level and it was low so i just thought it might have sucked some into the torque converter but when i toped it off same thing happened i towed it up there tonight and ima see what they got to say in the morning

STEPHEN_XJ_

im gonna look into this you go any pics of the trans cooler and how you did it as far as where you ran the lines
