I've got a LS swap car (78 Malibu) '03 Suburban 5.3 backed up by an '07 4l60e. The engine has '02-'06 LS6 cam and springs, cold air intake, exhaust manifolds w/3" dual magnaflows, otherwise stock straight out of the sub. The trans has 38,xxx miles, I put a stock converter w/the stator modified (gives 300-400 rpm over stock) and I put in a TransGo HD2 kit (in car mods) in it.

I'm a afraid I might have already killed the trans. I've read alot and made improvements but this morning I Dropped the max pressure and shift pressures (upper end of scale) to 80 from 96 and now the trans slips in 2nd and blows out of the vent.

I think that between the shift kit and raising the max presure to 96, I've damaged the 2nd band (bent tabs?).

A tranny sticky covering what NOT to do under any circumstances would be great. As I have found limited info on trans tuning and what I have found is pretty dated as to what version of the software was used.
