Conductor plates on the 722.6 don't have a computer in them like the later 7 speed so no special work is needed when changing one.

Is the key / gas pedal thing for clearing codes, clearing adaptives, or clearing learned driving style?

When you get the hard engagement ( park to Rev or Drive ) , does the transmission upshift properly or is is stuck in one gear? ( 2nd )

When you get the hard engagement, does the engine get pulled down like it is going to stall? Sometimes the torque converter clutch can drag making engagement harsh.
