I'd not a "chemical fix" kind of guy, but you can try a can of Trans-X or Seafoam in the trans with fresh fluid and see if there is a change. Surprisingly, that stuff can free up stuck seals for a bit. If a change is noted, then internal trans work is indicated. If no change is noted, then possibly you have a VB issue. You can also pull the VB and do a air pressure test to see how the front clutch responds when cold.
Broader is a good source of C4 performance items and experience.
Ps - I've had decent luck with the B&M kits, less so with the Trans Go stuff. So go figure. After years of screwing with C4s, I've come to the conclusion that VB are like carbs - you get a good one, keep it. And if one gets to not working right it can give you a real rash.

The trans is not original, it was rebuilt and the Transpak added before I purchased the car by the previous owner, that said, I don't know how old the rebuild is, and the car has seen some bracket racing plus some performance street play behind a mild 320hp 306. So it's not original, but it's also not fresh, is what I'm trying to say. If I can get away with a simple fix for a while that would be great as I wasn't planning on doing a trans rebuild at this time. I wanted to wait when I install a 347 motor later this summer. I suppose nobody plans for a trans failure (lol) so if that is the only way to go after I try cleaning the VB and adding some Trans-X then I will cross that bridge at that time.
Thanks for the tips.
