transmission service

Well the long list of preventative maintence begins as I just hit 100 k on my 2002 i6...

I just replaced the crank sensor and fan relay now my transmission is going to get attention. My question is do I flush the transmission or just a fluid and filter change? Also what service will the transfer case require? 2002 i6 4x4

No flush, just filter, gasket and fluid. I always buy my fluid (by the gallon) at the dealer, its by far the cheapest way to get ATF+4.

TC just gets new fluid

No need to wait for 100k for this service.
Trans should be done every 50-60K
TC 30-40K
along with allot of other stuff.

How much does the dealer charge per gallon?

I forget, and prices change.
Call and ask for service dept., than ask if you can bring gallon jugs and buy fluid.
It's been 50k mi since I have done mine and at that time it was something like $3 less a qt when having the dealership fill gallon jugs. I used windshield washer fluid bottles that I rinsed out with distilled water and left dry in the sun.

I just called the local stealership, to buy a gallon (with your container) is $19.40 a gal. which is $4.85 per qt...........

compared to $7-11 per qt at parts store.

I asked, and he did not know........
Most guys just think "fluid id fluid"

Last time I got it there I looked at the barrel and it was Kendall and I was able to find a data sheet on line. They get it from the lowest bidder.......

I would never get a transmission flush, especially on a transmission that is known to act funny when you don't use Mopar fluid.

If you're doing the fluids, I would also change the fluid in the TC and the diffs.

I have never heard anyone say that before today, and not had any problems in my own, either. Sounds like a one-off anecdote to me.

I think by "MOPAR" fluid he simply means ATF+4.

Or if you are referring to the flush, It's pretty common for a total flush to cause issues (or expose them) with higher mileage transmissions.

Just because i don't think it's been mentioned , if you have quadra-tracII - NV247 transfer case , you should use mopar NV245 fluid and not ATF+4 .

Cheapest ATF+4 I know of is SuperTech, just over 4 bucks a quart works great. A flush done properly is no problem but most here are afraid of them because flushes are not created equal and how do you know what you're getting?

If you perform the drain yourself you may want to consider adding a drain plug to the tranny pan as well. You should still fully remove the pan and replace the filter. The plug just allows for a cleaner draining process.

Pretty much this. Despite there being many brands of ATF+4, I find it best (if you have the funds) just to go with Mopar ATF+4. I've heard of problems being caused by using other fluid, but I'm not 100% sure if that's actually true.

I'm sure many people have had good experience with using fluid that wasn't Mopar. I know Honda ATFs will fail if you don't use the Honda ATF-DW1. Better safe than sorry.

Yup, I agree 110%.
