Due to the interest in and success of our 6L80E/90E conversion projects using a Small Block Chevy engines (58X/24X Gen III+, Gen II, and Gen I) we have discovered a big problem. Even though we can now independently manage the 6L80/90 transmission, not everyone drives a SBC vehicle and not all vehicles (SBC or otherwise) have the transmission tunnel space capacity to accommodate a tall & long 6L80/90 transmission. So we looked into the matter and will be introducing another TBMSport exclusive 6-speed automatic transmissionsthat will fit in your traditional late model rear drive application with little to no floorpan modification.
The mission was simple. Fit a modern cost effective and high performance-ratio 6 speed automatic transmission system (transmission & controller) in the space where one has or could reasonably fit a GM TH-400/4L80-E transmission. So are looking into our next project: the non-SBC engine in the traditional small capacity transmission tunnel vehicle. Now is your chance to get the 6L80E/90 performance in your favorite late model RWD vehicle. Be it the late model GM Diesel 6.5L, Ford/Mercury/Lincoln, Mopar/Dodge/Chrysler/Plymouth, Buick/Oldsmobile/Pontiac/Cadillac, AMC/Jeep, Jaguar/Rolls Royce/Bentley, Let us know which engine performance application you want to see next step into the new millenium. Better acceleration. Stronger transmission (up to 700 lb/ft TQ). Lower Highway RPMS.
