Sounds like you've made some improvement, but you need to adjust the band per the service manual......the next time you "get in the mood". "Finger tight" ain't it.
Yea I know... 6ftlbs tight and then backed out 2 turns. I always had flare when I did that though. So I'd probably have to drop the pan and adjust the throttle pressure on the vb and at this time I dont want to drop the pan again until I have a new tc.
