It is the valve body that was in the trans when I bought it, don't know brand or low band apply or how much pressure the builder increased it to. I suspect the 1st gear ratio is stock as I've never done a gear change other than have the big block planetaries installed when it was overhauled.
There is no flare up at either shift point.
I launch with both hands on the wheel and put hand on shifter as soon as the front end comes down. When I launched with hand on the shifter I would sometimes pull back on the shifter without realizing it at the launch, so I now leave with 2 hands on the wheel.
I don't watch the rpm on the tach for the 1st shift, I watch the track and see shift light in peripheral vision.
I agree I don't think there is anything wrong with the tranny was just wondering if something simple like band or pressure adjustment would make the shift faster. If not I may have to get a tach with 2 shift lights, which I was hoping to avoid since. I'm a cheapskate plus I just bought a new tach 2 years ago to replace the one that came with the car and is at least 20 years old.
