1998 C1500 - Just firming up shifts
I'm really having a hard time finding much info for this truck with it's redhead stepson of a blackbox PCM.
I just want to firm up the shifts a bit. Drivetrain and tires are stock. I don't want neck snapping shifts, just quicker and a little firmer.
Auto shift properties > Shift Pressure
Should I just bump up the max pressure a few (stock is 90) and scale up the Shift Pressure Upshift tables a bit? And how much 90 up to high 90's?
Then I've read I can reduce and eliminate some of the delay in the shift time tables.
Should those two tables, and max pressure do what I'm after? I really don't want to mess with any of the TM stuff on a higher mile vehicle (130k)
Thanks
