Let off slightly when you shift

Re: 700r4 delayed hard shifts

after reading other posts, I think my problem is in the tv cable or clogged throttle valve? the long delay between hard shifts...was very disapointed with car was told mid 13 car ran only 14:20 at 98mph but i know the tranny thing cost me a few tenths..I gotta go thru car call vortec and measure pulley to see how much boost its suppost to be?? ran like 3-4 psi not 7-8psi? got all winter to get her going probley send s/c out for rebuild..either way cars cool, always loved the '91-'92 gta's...just want it to run as good as those ls1 t/a's...will see...thx

The TV cable should be tight at WOT. Were the shifts at WOT ok before the supercharger?

Stay the hell away from the B&M Trick Shift. Call me tomorrow at 909 7951876 in the afternoon PST and lets talk on this. Dana
