2004 XK8 - ZF 6HP26 questions.

The adaptation drive cycle is a very particular thing, no normal human would ever drive a car the way you have to to successfully complete the cycle. You have to be super gentle, keep the throttle in a very narrow range and a particular speed when the shifts occur.
That's why I say if you are going to do it, then it's best to have a ride along to manage the laptop and trigger the steps and to find a very empty piece of road.

I do have the iCarSoft unit that can read tranny oil temp. Seems a lot easier to just use a IR gun on the bottom of the pan as you are laying down there. Does it make any difference which method you use???
By the way, I say you old post on the surface mount resistors for LED load on rear light. That looks pretty neat (except for the soldering) and will now be on my list of things to do!

As fmertz reminded, do shift the gear lever through all the positions and hold each one about 3 seconds to fill the valve body and associated passages. I try to do this while the trans is warming up but before it reaches 30C.
Cheers,
Don

The plastic oil pan is a poor conductor of heat, so you can't get a reliable temperature reading on its lower surface. If you use an infrared thermometer, aim the beam at the fluid dripping out of the fill hole. Either a measurement of the dripping fluid or via the trans oil temp sensor should get you close enough for a good fill.

The entire ZF ATF process is so much easier as a two-person job. I have done it five times on two different cars (my wife's 2006 XK8 and my former 2005 S-Type) always with at least two people involved (and several times with three people involved). You will be much more precise with the various required steps if you have a partner working with you....
