4L60E part throttle shift points

[JD1964]

Only thing I can think of that might make you think twice is whether or not you have access to the Performance Shift Table.

Thanks for the analysis of my overall mentality in the shift timing regard. I had been thinking of the performance table. At the last boneyard visit I even snagged a momentary on / off switch in the form of a rear window defroster switch from an 86 Cutlass S. Lights up when on too. :-)

I dont imaging changing the shift timing much with performance mode though. Maybe some data for some harsh gear chirping action that I can turn back off. Right now all my pressures are stock.
