Mopar!
I have a 904 Behind my 408 stroker. It seems to shift fine while at lower rpms. But when I run it up to say 5000 rpm it seems to slow shift only into high gear. The other gears seem fine. Since ive had this problem ive swapped out the clutches for high preformance clutches. Changed my shifter, changed the valve body, and changed my torque converter and still have the same problem. My setup is 904 with racing clutches I think there altco? Reverse manual cheetah valve body. It has the low first gear ratio. Any ideas or help is appreciated.
