2. I like the smoother shifts at low tranny fluid (i.e. it's just below the 'add one quart' on the dipstick), is that hard on the tranny? (assuming the problem is not as noted in quest 1)
3. Is it possible that something is sticking (governor valve)?
4. Am I using the wrong stall for that cam and causing that hard shifting (I read that you should use a high stall with a tall cam)?
5. Am I just paranoid and the shifts should be this hard so just fix the rear seal, put fluid to normal zone and live with it
High fluid level shouldn't cause the hard shifts/ gear engagement. Low level will cause soft/slipping shifts= bad.
That Cam needs at least 2500rpm stall. Operating range is 2500-6400rpm.
With the Engine running the fluid level should be even with the Trans Pan mounting surface. You should drop the Pan & check the level marks on the Dipstick.
The Bang Shift is caused by the Shift Kit, High Idle speed & Low Stall TC.
Higher stall TC should calm it down and help creeping in gear.
