I trying to figure out what to change in my TCM tune to eliminate a Trans Turbine RPM spike on my shifts that causes me to tap the rev limiter, close the throttle and cut fuel. You can see the engine rpms stay in check through the shift, but as soon as it appears the trans is completing the shift, the trans turbine rpms sky rocket to 7,000+ rpms. Thoughts?
This is a Paramount Super Pro trans, 2800 stall, Ding's Valve Body, behind a 4.5L Whipple setup with a 426ci motor (around 900whp currently).
