Rebuilt 904 w/ tf2 shifting woes...

well now, that presents a conundrum. With a 10.5 advertised compression ratio, you should be having plenty of torque/power.
Have you done a compression test? and if yes, what were the results?
Ima thinking I went down the wrong road, and the compression test should prove it.

Compression test on engine? Yes. Results were good. I can't remember all the #s but it was mid 150s except for 2 that were in the mid 140s (if my old age memory serves me correctly)

Pressure test on transmission? No. We were going to but Tony couldn't find his transmission pressure tester lol.
