retarded cam timing shifts the rpm range HIGHER

Most tranny modulators have a screw inside the vacuum connection.....turning it in raises the shift points (to an extent)

If manual shifts still are limited to 4K, you'll likely need a shift kit for the C4...

Depending on cam and application, you might consider advancing cam for auto app...

Post specs on cam and engine and converter...
