Tuning the ZF5HP19 Auto transmission

[Zedebee]

Are there any tuning options for the 5-speed auto as fitted to the E85 2.2/2.5/3.0?

xHP offer flash upgrades for the later ‘boxes, but I haven’t seen anything for this one.

It is possible to change the shift points but it’s an expert job, why do you want to change it ?, if you want to change down sooner use the paddle shift. Have you changed to oil and filter they usually work better with a little TLC, do you have a sport button on yours

Only wondering if it’s possible to speed up the changes, i.e. the reaction time from pressing a paddle or the lever in +/- mode. Compared to a modern auto (I was in a GT86 previously) it’s a bit slow. Yes I have a sport button which certainly livens up the experience.
