Alright so I’m finally getting around to fixing a few small things with my Buick now that a buddy is talking a bit of smack. I have probably built 30ish 200-4rs with great success in the past so it feels weird asking the questions but I will readily admit I am not a valvebody guru and am looking for any hints or pointers. I launched off the Stage-rite Tbrake on my first pass of the day and all went well; 1-2 at 5800 and 2-3 at 5700. After that I had 3 more runs and gave the transbrake a try each time. As soon as I launched, the car was instantly in 2nd gear and first was nonexistent. Obviously this killed my 60 fts. I run a KC valve body as well as a deep pan and filter set, full billet internals, dual fed, CK servo etc….. It runs great on the street and all the shifts are quick and firm like my other builds. I use CKs shift kit but I blocked off my 1-2 accumulator. It does seem to quick shift into 2nd earlier than before those passes if I start to lean into it or if the tires break loose in 1st, but on the street it’s hard to tell. Does an issue like this ring a bell for anybody? The transmission shifts and acts completely normal under all other driving conditions. I plan on pulling my PTC to have it stalled a bit tighter soon and was hoping to get a few ideas before just replacing seals and clutches and hoping for the best if I don’t find something obvious.
