auto trans gurus - 3-4 shift question
I have converted tranny to manual operation, and 3-4 wot upshift
valve is new.
I have readjusted TV cable and everything, including all other upshifts
and downshifts is great, but I can't solve this 3-4 upshift problem.
Part throttle 3-4 is good, but as rpms go higher it gets softer.
WOT upshift at ~4500 rpms is still working, but if I try to upshift above
that rpms, nothing happens until I relase throttle.
