If you simply throw a 'Vette/093" into a trans that's.....
1. Not calibrated for it.
2. Has loose/excessive Band clearance
The 1-2 shift will definitely firm-up....

What I'm outlining is a complete hydraulic re-calibration of the 1-2 shift!

Can we buy a used valve body, perform the upgrade, hot swap? Can the valve body with this upgrade be purchased somewhere?

I haven't covered any Valve Body modifications up to this point, The only component in the Valve Body that influences the 1-2 shift feel is the Accumulator Valve, Spring & Bushing, This component controls the opposing pressure applied to the 2nd & 4th Accumulators. I was going to cover the that....But this thread will likely die as it involves actual work.
