How much better is a 4T65-E HD trans?
Could I use the wiring and electronics from my wrecked 97 NA buick, and rebuild the trans myself later as an upgrade to be a 4T65-E HD? yes I know my old buick only has a 4t65e non HD trans. but I don't wanna buy a whole new tranny when I could just rebuild mine for A: more torque and B: to be an HD tranny if its possible for cheaper than a brand new tranny and wiring
Edit: I just got a 96 supercharged is why I ask
