I have a 01 Z28 with a u7198 predator and my question is about shift pressure and shift firmness> I just had my tranny rebuilt I Lost 2nd gear lol. Well my question is will changing shift pressure *making it higher* and shift firmness mess up my tranny someone help . Also does this do the same thing as a shift kit???!?!?

Adding line pressure will generally keep the tranny alive longer since it eliminates slippage between gears, which keeps heat down in the tranny, and heat is a transmissions #1 enemy.

It is similar to adding a shift kit, yes.

Thanks

We do not allow you to go far enough to hurt anything, so feel free to add pressure until it is where you like it.

TM is what protests the tranny from making too much torque, turning it off will allow you to make as much power as possible without the PCM stepping it, but it may shorten the life of stock drivetrain parts in a high HP application.
