Guessing responses are going to be impossible to very hard. Just spit balling a possible future project. From my XJR parts car I have not sold the Mercedes tranny, drive shaft or TCU. We all know the ZF is a common failure mode in these cars. Not hard to find a XJ8 or XK8 in good shape with a bad tranny cheap.

 

I imagine you’d need software writing capabilities with the factory installed computers. To the best of my knowledge, your best bet is to contact Count Iblis (misspell?) here on the forums as I know I believe he was part of the development with the X300/308 supercharged cars. Somebody correct me if I’m wrong. Most realistically though would be to have a stand alone system running it all.

 

Thanks. Busy with my current project but always thinking of the next. I have had that transmission listed on eBay for months for $700. First week got an offer of $600. Should have taken it.
