C4 X BRONCO II T/C (11.500 )

C4 X BRONCO II T/C (11.500")

The C4 automatic transmission is the most commonly used transmission. It is durable and very easy to find. Due to design changes, we advise that you select a 1970 or newer C4 tranny. The C4 has a removable bellhousing, so make sure the bellhousing pattern is compatible with the new engine and flexplate. We recommend a 157 tooth flexplate. Be sure the starter motor engages the flexplate correctly with the bellhousing. The C4 is 17” long. Combined with the new adapter length, use the best adapter suited for your application. Kits include a new 25 spline output shaft, adapter housing, vent cap & necessary hardware. These adapters have provisions to bolt the stock transfer case shifter bracket in its original location. The 1st gear ratio is 2.46:1; 2nd 1.46:1, and a 1:1 3rd gear ratio. P/N 50-8401 - C4 to Borg Warner 1350 T/C. Adapter length of 11.5” (28.500” O.A.L.) PN50-8402 - C4 to Borg Warner 1350 T/C.
