Trans oil change?

I have about 37k miles. I have been searching here with no luck. Should i do a trans oil change? What do u guys recommend? Should i do this a the dealership? Or try it out myself? Would I need to change the trans oil filter too?

Thanks

Re: Trans oil change?

What year? The 14's+ are sealed for life and are supposed to be maintenance free. If you don't have a sealed unit there's nothing wrong with swapping the filter and 4 or 5qts in your driveway but that's pretty low milegage to be thinking about it. I'd say diffs and transfer case would be before the trans.

Re: Trans oil change?

theres been quite a bit of debate here and elsewhere on that topic...quite a few youtube vids on the process if you're so inclined. the pan/filter are several hundred bucks.

"lifetime" trans fluid doesn't necessarily mean lifetime, it just means "out of warranty".

No mechanical component lasts a lifetime. Metal wears, synthetic lubricants break down, and filters fill up. I will be changing mine at 40k.

Re: Trans oil change?

For the 8 speed, in Australia they are recommending fluid change at 100,000kms/60,000miles. I'd be taking it to a ZF transmission specialist.

An interesting youtube clip, 47 mins in is looking at the condition of the filter:

Re: Trans oil change?

Glad I read this thread. I'm too new to this to know about the trans and that's what the stealership told me.

In the NAG1 it was cheap and super easy to change the stuff out and a nice earls 19 row dropped the trans temps like mad. Anyone know if this trans benefits in the same manner?

Re: Trans oil change?

I found this on another Jeep site. It seems the V6 guys got the short end of the corporate pokey stick here

".the ZF tranny that comes in V6 equipped rigs has the 845RE version of the 8 spd tranny, V8's get the 8HP70 version. The difference being that the V8's ZF 8HP70 is made in Germany by ZF, whereas, the V6's ZF 845RE is made by Chrysler "under license" from ZF. There seem to be issues like this with the V6/Chrysler manufactured unit and nothing to speak of coming from the V8/ZF sourced units other than programming break-in. It was one of the reasons I opted for the Hemi."

What's going to scare you off on anything involving servicing this transmission, (ZF 8-Speed), is cost. First off is the cost of the fluid. You can only purchase it at Chrysler dealerships and it costs $40.00 A QUART, and it requires 10 QUARTS.

Next is the "filter". It is part of the transmission oil pan. In order to change out the filter you have to replace the entire oil pan / filter combo. Cost?....... $270.00+. So, in just parts and fluid you're looking at over $670.00. That is providing you do it yourself. If not you have to add labor at $90.00+ per hour. Bottom line, it's going to cost you as much or more to service this thing, than it will to rebuild most older automatic transmissions.

Also, if you use ANY other fluid other than factory recommended fluid, it will void your warranty. Chrysler has got us by the balls. At least until someone produces a cheaper fluid and filter combo that doesn't take a second mortgage to buy.

As silly as this sounds, you're better off buying the Lifetime Max Care Warranty, and just drive it until it fails. And just hope it does so walking distance from your house or dealer, and not when you're towing your boat or R.V. on vacation.

I agree with you, i have always been an avid changer of trans fluid prior to this vehicle but if you do 30-40k changes on this one by 150k you have about paid the price of a new transmission in fluid change cost which is rediculous. They say it is fill for life with no recommended change interval, so follow the manual dont change it and let maxcare cover it if fails because we would be following the recommended maintenance right lol. In reality i may just do 1 change around the 80k mark, if i remember right i think that is where they recommend on the australian maintenance schedule which is the same trans not sure why they have a different maintenance schedule. Previous cars $75 for a drain and fill every 30k in my driveway was easy and cheap, times change.
I think this depends a lot on how long someone plans to keep the jeep, if you keep less than 100k just leave it who cares and dont change, if you plan on keeping for the long haul way in excess of 100k than 1 change may be a good idea. Just my opinion

Does anyone know if this is still the correct part number for the transmission filter/pan? I tried ordering it from Quirk Parts and received an email from them stating it's not available from the manufacturer.
