LR3 Transmissions, how robust are they?
#12
I've heard the most critical part after resetting adaptations is to follow the instructions on how to drive to get the transmission to "relearn." If you just go in and reset the adaptations and don't follow the 55-10mph coast x 5 routine, you're likely to have issues. Doing it for the sake of doing it without any reason is also asking for trouble (at least, very little chance of any benefit).

Finding a suitable place to do the procedure is difficult. I had to wait till I was visiting family out in the country, where there is very little to no traffic and speed limits that work. From what I read, it doesn't have to be performed back to back (i.e. you don't have to do all 5 runs without interruption), but probably during the same drive cycle.
I had a specific ZF manual print out that went over the procedure, but I'm not finding it online anymore. The procedure seems to vary by manufacturer, with BMW saying it needs to be done 9(!) times, but the gist is the same across all: accelerate slowly till the transmission shifts to 6th gear, then coast down to almost a stop before using the brakes and repeat.
Here's where I first found the procedure:ZF 6HP26, 6HP28 Transmission Fluid Service Procedure
This file has a LOT of info on the transmission and the relearning procedure for VW/Audi/BMW: http://www.natef.org/NATEF/media/NAT...sion-6-8HP.pdf

Can someone please provide some insight on the tranny filter? Specifically, is the OE filter of the variety that is reusable? I know that some are a reusable metal element that you just clean and replace. Is this of that variety? I guess since these transmission were supposed to be "sealed for life" I'd be surprised if they are...then again, I'd be surprised if the filters were of the serviceable type too since they are integrated into the plastic pan.
