Hey guys,

Working the bugs out my 64' And the transmission doesn't want o up shift into the final gear until late, first two shifts are nice and smooth but the third is late, I need to be at 2500rpm for 20 seconds before she will shift.

Any ideas where to look first?

 

you try adjusting the throttle linkage?

 

Yep! Tried that, tried a new BFE kickdown cable, new shifter cable etc!
