Transmission Slipping *Question*

Hey,

I have my 01 Sahara and it's got about 118k miles.
When I first get her going in the a.m. she slips once or twice going from 1st - 2nd, and then it goes away for the rest of the day.

Everyday for about a week now.

How alarmed should I be? Is there anything I can do myself or is this a run don't walk to my nearest shop kind of a deal?

Your wisdom is appreciated. Thank you!!!

Does the fluid smell burned?
Change the fluid and see if that helps.

Mine did this a couple of years ago when the weather started cooling off. Changed the fluid and filter and it has been fine every since

from my trans mechanic, which i trust, he said that to keep an auto trans for a long time you need to change the fluid every year.

When was the last time you changed the fluid and filter?

The quickie oil change places don't change the filter. They give all kinds of bullsh-- excuses why they should just suck out the fluid through the dipstick tube.
They lie!

Make sure to only use ATF+4 transmission fluid. No Mercon or generic ATFs will work properly in your Sahara's 32RH automatic transmission.

I haven't been to the mechanic yet, haven't driven recently, but a friend of mine was telling me that replacing the fluid and filter right now might make the slipping worse? How is that possible???

The rumors are rampant that changing the ATF and fluid can somehow wreck a transmission by letting chunks of stuff break loose. In my own opinion, that's not all that likely in most cases. With only 118k miles, I doubt changing the ATF and filter will do anything except possibly help. If it doesn't help, odds are its bands need adjusting which is a minor inexpensive thing to have done so long as you have the work done by a small independent honest transmission shop. I'd never trust a chain transmission repair shop like Aamco to do anything but overcharge me and claim the transmission has problems it really doesn't have. Chain shops have quotas to make and not all are scrupulously honest in how they make their quotas which are often quite high.

And rday78, you are certainly welcome. Nice that you figured out how to rebuild yours and actually sell it!

I agree. I also suspect that this rumor originated from a Midas shop as a way of selling more product. Be sure you use ATF+4 and a quality filter (not fram! - go with OEM kit if at all possible) and let it sit overnight before dropping the pan to catch as much fluid as possible.

It is very possible that it was serviced at some point, and the wrong fluid installed. If valve body problems become apparant after the fluid/filter change, it was on life support LONG before you noodled with it, so proceed with confidence.

The 32RH is a reworked, older Chrysler 904 transmission with an electronic lock-up assembly; it was also known as a TorqueFlight 904, 909 and 30RH prior to the change to computer controlled LU assy.

3 - number of speeds
2 - torque handling (2-300 ft-lbs)
R - rear wheel drive
H - hydraulicly controlled .

It is very possible the fluid is burnt if the lockup unit is not functioning properly. The electronic lockup lowers operating temps and longevity in this unit, which was badly needed. If the fluid looks/smells burnt, head for a dealership or a good, local independent shop for help.

Jerry is 100% correct! New fluid cannot make it worse! Why eat, you'll just get hungry again?

As a transmission ages bands and clutches wear slightly, just like brakes, the particles sluffed off are caught in the filter (with brakes the particles blow away where we can breathe them.)
At the same time all the little rubber seals wear a little and get brittle, leaking and not totally doing their job. Pressures drop, it slips more.

New fluid AND A NEW FILTER gets rid of the dirt particles, and the new fluid has a conditioner that softens the seals -- ALL GOOD!

Don't get talked into the quick "suck it out and refill" schemes - MAKE SURE THEY REPLACE THE FILTER.

I just added some ATF to my Jeep today since the fluid level was low. The brand is CAM2 (I guess its pretty generic) and I have a 32RH auto trans. Should I be worried? I didn't add much, a little less than .5 liters.

My 98 TJ 32rh auto trans was long shifting from 2nd to drive. I changed the trans fluid and filter. Ran 12 qts thru it to flush it. Helped about 85% today I talked to a transmission shop and they told me that there is a Service Bulletin on this problem. He said the seals get hard when cold and need to be softened up. He recommended TransX an additive for 30 days or until it stops slipping slow then flush the trans again. Anyone else ever heard of this?
