Here is what we did..

We washed out a T-Tech machine with simple green (to remove all old ATF fluids and residue) filled it with fresh clean castrol.

Unbolted the tranny cooler lines connected them to the T-tech flushes the cooler, lines and valve body.

Once the fluid came out uniform in color we dropped the pan.

threw the pan out, installed new pan and proceded with the fill.

dropped the driveshaft pulled the tranny back to have access to the TC, he flushed it and filled it.

I didnt see what he did with the TC since I was in his office working (gotta love on call)

He was able to verify that he has used the castrol shell spec in other ZF boxes.

400 miles later its shifting smooth as glass.
my P0286 and P0741 have seemed to dissappeared for now.
not sure if this is normal but from a rolling 20 I can turn DSC off and just roast the tires as I accidently found out.( which is ok because I have a surprise coming)

As far as the fluid that came out.. it was dark but didnt smell burnt or like roasted almonds.

Total procedure time with Lifts and tranny jacks and air tools a little over 2 hrs with 3 of us monkeying on the car.

 

The title sounds like the movie will be out on DVD soon at BlockBuster!

 

It may on certain on certain cars, Ive seen some that have not.

Dont hold me to it 100% he might have done the split as a precaution.

myself and my friends dont really play when it comes to maint. he wanted to tear down the gearbox and wash it.. lol

 

So an update cruising on the interstate cruise set at 90 mph over a 300 mile trip smooth as glass no shuttering no TC lock up issues.

 

Well that's good. So hopefully you've avoided a major service.
How many miles on your tranny?

Bob S.

 

43k. I think I got a slew of codes because
The car sat for a while undriven. And when I brought it back from FL it wasn't expecting to be pushed 85-100 for the majority of the 23 hour drive back only rest it got was gas and food

 

so 1K miles later smooth as glass still, MPG's are still in the mid-upper 20's

During the trip from Dallas to Sherveport on cruise set 75 I was seeing an AVG MPG 25-27
