I have a 1989 D100/2 wheel drive.I installed a 727 TCI trans with an aftermarket aluminium pan .pan is approx 3 inches deeper. y pipe needs to be moved about 1/1/2 to 2 inches forward.Its about 1/4 inch away from pan right now.My options as far as I can determine are/// 1 have muffler shop bend or fabricate a new pipe 2 buy a pipe from Summitt//walker brand and work on refittment// cut or bend etc. Question//is 4 wheel drive pipe //does it go around of back of transmission etc. Anybody put in a tranny with a deeper high capacity pan and run into this fitment dilema? I'ts become a real pain in the::doh: .
