I've been trying to find a way to get the 5 speed SRT6 tranny to shift faster both up and down. The Mercedes supercar SLR still uses the Merc 5 speed auto, all be it's greatly modified.
I want the ask the Crossfire SRT6 nation out there if the PCM/transmission computers on the SLR can be copied and or adapted to our beloved SRT6's?

Second option: would the tranny controller or PCM from a SRT LX car improve shift speeds if in fact it does shift faster in the first place. When I have driven those cars the Auto-Stick does appear to shift faster.
