I had some doubts about whether my mildly modified 727 Torqueflite could live a long happy life behind blown HEMI power, so I contacted John Cope, owner of Cope Racing Transmissions. John is a foremost Chrysler performance transmission expert, and is highly regarded in the Mopar racing community for building top notch performance Torqueflites. After some discussion, we decided to go with one of John's Pro Race II transmissions. It's his ultimate foot brake unit. The list of bulletproof parts inside this transmission includes:
Griner reverse manual valve body with low band apply Bolt in sprage Alto Red Eagle racing clutches Kolene steels Thicker band strut Red lined bands Teflon rings Front billet servo Rear billet servo 4.2 billet 2nd gear lever B&M deep aluminum pan & billet filter extension Modified pump support for more flow to the high gear clutch Rollerized planetary gear set in 2.45:1 1st gear ratio with steel spline, and rear roller kit Hardened pump gear set Parts are just parts, but add in CRT's expertise and special modifications, and you end up with a very durable quick-shifting transmission that will provide years of trouble-free service. Having that kind of quality gives me peace of mind every time I nail the throttle and grab a gear.
The complete rollerized kit, which includes, front and rear planets, front and rear ring gears, rear roller kit, and polished output shaft.
Front & rear billet servos with stainless steel springs and thicker retainers
