Thats it above.
I will have to do this because of my "rebuild".

Seems like for every change I think something has improved. However after driving for a while it is same old -same old again. Wondering now if transmission temperature has anything to do with this. Seems to shift fine on cold start. Trying to figure what my next step should be.

And the weather today is absolutely gorgeous! A shame to see the XK languishing in the garage. May have to take the TF out for a spin - short one at least...
Will definitely report what progresses when we get to it.

As with most, stuck at home, so been watching videos on ZF 6HP26 repairs; saw in at least one that 3 of 5 or 6 (?) solenoids did not hold pressure and were replaced. The video was at a trans shop, and he sent the solenoids out to be tested...or perhaps it was the valve body and solenoids that were sent out...not sure.
Anyways, got me wondering if this is something that should be done....but where to send is the question.
Mickey....are you replacing the solenoids?

Would be cheaper to actually by new solenoids rather then send out to test and find several bad ones and then buy a complete set new. You cannot buy individual ones as far as I can tell.
They are all the same age so if one is bad others are likely to be bad or go soon maybe.

I do not think that I have to do the adaptations run with jlr sdd.
Yesterday I drove about 20 miles with two fairly hard acceleration runs to below 100 mph with smooth gear shifts.
No traffic when I did the acceleartion runs and it was not with pedal to the metal.
No DTCs at all for the transmission but I did have a fault caused by an air leak behind the MAF somewhere.
This is with 2007 XKR solenoids and valve body in my 2005 XJR.

PERFECT!.....and yes I agree the solenoids would be new. I was just not understanding that the solenoid pack was included with the assembly you got.
Now I am sure this would fix the trans issues of my XK8...and hopefully yours as well.
Did you ever get the four tubular seals from Whatever It Takes?

Since I am almost paranoid about this transmission, I crawled under yesterday to double check the fluid level. It was low just about 0.75 liters. I don't understand why or how. I did the fluid change by the book. Only good thing is that I have not driven much since i did the last fluid change and hope that no damage was done.
Now we'll see if the added fluid will affect the shifting????

If you dropped the pan and changed the sleeve, you can typically pump 6.5 to 7 litres of fresh ATF into the 6HP26 system....
If you do just a drain-and-fill, you can typically pump just 4.5 to 5.5 litres of fresh ATF into the 6HP26 system....
Do you remember how much fresh ATF you were able to pump into your system?

Just topped mine up yesterday. I am now using Mercon SP.
I topped it up when temp was about 20 C and waited for the fluid draining out to reach 40 C before putting the plug back in which I never get in first try.
Very important to take the temp of the fluid coming out to get the correct temperature OR use something like jlr sdd to see what the the temperature is.
Taking the temperature of the pan itself will give you an incorrect reading.

Probably will be another week or so before we swap this out. Gettin' anxious, but staying safe!
