I've been having problems with my 2 to 3 shifts since I built this car. 2 different valve bodies, 2 different transmissions.
It is flairing about 800 rpms on the 2-3 shift.
I've been adjusting the kickdown band finger tight then backing off 1 turn.
Someone else has told me to tighten it to 100 inch pounds then back it off 2 3/4 turns.
Here is a photo of the log.
