Thanks for clearing that for us.
I'm guessing it will smoke the clutches in the auto tranny, because the transmission computer is not calibrated for the engine speed. The manual Sprint Booster might be putting too much power to the tranny too early, and the solenoids in the valve body may not be opening early or late enough to put the pressure to the clutches in the drum during a shift, this off timing might cause some major slippage and burned clutches.
Kinda makes you wonder about the long term effects on those autostick trannies when using the SB.
