Issue with kickdown using BPE cable kit

Mplex2000:
Accelerator cable is adjusted fine now. Difficult to do because it's on the same bolt as the kickdown cable
Throttle pressure or kick-down cable hooked to same bolt? Are you referring to the clamp that secures both cables to bracket, or where cables attach to throttle lever on carburetor?

Using a BPE universal cable bracket which is similar to a factory bracket, and their throttle pressure cable (basically a stock part used on later vehicles) allows for fine tuning once clamped by depressing a button at carburetor end of cable.

The pull travel of kick-down cable must be in proportion to the throttle cable travel or shift quality will suffer. BPE includes a correct throttle pressure cam that attaches to top of shift shaft on outside of transmission and requires use of Chrysler throttle shaft adapter to make both throttle and transmission play well together.

If you are using a hodge-podge of parts it can be difficult to synchronize them to allow proper shifting. Also, if driven with improper throttle pressure you may have damaged front clutch pack from low internal pressure that makes for soft shifts.

Another place to look for problems unrelated to above cable issues is leaking valve body caused from not being properly torqued to transmission allowing internal leaks. This condition will cause all kinds of problems that don’t make sense using diagnostic chart in service manual.
