So, I'm in the process of rebuilding my 1997 Aero's transmission. While I'm at it, I will also be installing a quaiffe LSD. I definitely don't want the transmission to break any time soon, since my car is at stage 5 at the moment but may be seeing a hx-35 sooner or later. Now, my problem is that I cannot be shipping my transmission out, since I'm actually in Puerto Rico. I would like to know what could I do (or get a shop to do) in order to make my trans. less likely to break at least, if not bulletproof, and any ideas on the prices?!? Any parts or gears from other models that I could use, or hardening treatment to the internals? Thanks!
