I'm using the SK transgo kit and noticed they use slot 4 holes on the retaining plate, install a coil spring and a black and blue spring inside the original spring for the 2nd piston. I noticed the hd2 kit doesn't make you grind 4 notches on the plate and only uses the blue spring with no coil spacer. Also noticed the 1-2 accumulator instructions are different.
which method is considered "better"? Using 093 servo.
the only thing I can think of grinding notches would be for the purpose of slowing the band but that would only be useful when having big clearance on the 3/4 clutch stack.. trying to just figure this out.

 

Mixing kits is generallt not a good idea unless you know specifically what you are trying to accomplish, That said either setup will work fine/
The purpose of the notches was to prevent hydro lock on the servo cushion springs though IMO its a pointless mod as this actually does not happen, So I would not concern myself with it.
