Neat PDF I found on how ZF trannys work in general
does give a bit of insight of how we can modify signals for more line pressure<ul><li><a href="http://www.bmwmotorsports.org/BMW_docs/electran1.pdf"><Click></a></li></ul>

I like how detailed the PDF is
If we can find one like that for our cars it explains solenoid operation and all. Even explains the more duty cycle the less pressure the less duty cycle the more pressure. I now understand how the soldenoids work and how they dump pressure or keep it. Seems if we put stiffer springs in there the valve will be harder to open and therefore keep the valve from opening and it will have more pressure? Most of our answers seem they are inside that ECU, I always wondered what slip speed means and now I know we need someone to hax0r in to that box and 'adjust' some things

Re: here ...
Ok FLA is and Audi PN, FAQ or EMP is the ZF Part Number
All our trannys are 5HP19FLA FL = Longditudinal drive shaft, A = All wheel drive. The model # is 1060 040 063. I believe both trannys are identical but might take a different TCU. Why would you want to exchange the tranny for a FAQ?
