B&M has you covered with our high performance flexplate designed for 1962-up A727, A904 transmissions and all internally balanced Chrysler, Dodge and Plymouth V8 engines with 8-bolt crankshaft flange. Features include high tensile strength steel construction to resist elongation and cracking, 10.00 inch bolt pattern and comes with SFI 29.1 safety certification insuring the ultimate in safety and performance. The assembly is then Zinc plated and treated with a Chromate Conversion Coating for added corrosion resistance and durability.

from
$199.99
Recalibrate your automatic transmission for optimum performance! Select the mode that best suits your application Improves transmission life Transmission removal not required APPLICATION: 1966 to 1977 Chrysler, Dodge, Plymouth TF A-727 and A-904 The next step up from the Shift Improver Kit is the Transpak. It has all the features in the Shift Improver Kit plus it provides additional driver manual control (GM TH-400, 350, Ford C-6 and Chrysler Torqueflite only). Most stock automatic transmissions won’t downshift into low gear above 15 mph, and automatically upshift at a predetermined speed no matter what gear you’re in. With the Transpak, you can downshift at any speed, and you can hold the transmission in first gear to any speed that you want! This is an asset when you’ve got a modified engine, and you want additional RPMs, or you’re towing a trailer or driving heavy loads downhill. Stage 1. Heavy Duty For street rods, normal passenger vehicles or other heavy duty use. Firmer shift feel but not harsh. Improves transmission performance and life dramatically without loss of comfort. Normal automatic operation when in Drive. Stage 2. Hi-Performance Street For full performance street use. Essentially the same as Heavy Duty mode except shift is much quicker. Retain full automatic features and standard shift points with selector in Drive.
