Hello there again. I just ordered a sonnax performance pack believe part number is hp-4l60e-01, and was wondering what else I should add when I'm down there. I've seen recommendations for the sonnax 2-3 hd shift valve, superior 3-2 down shift valve spring and valve stop, and transgo hardened separator plate. I already plan on a i6 torque converter as I have the 5.3, i already have a front mount trans cooler, and the Corvette servo. I know to replace gaskets and fluids but I'm looking more to work on the VB only once if possible. Btw I'm scared to open up the trans for a rebuild and would only do so if it grenades and i know there are better stalls to go for while I'm there but money is a little tight and I'm not trying to build a race car just a fun SUV that I only drive currently about 3k a year.
