727 TF3 problems and pressure test

727 question! Freshly rebuilt 727 with TransGo TF3 kit. Low seems to be binding up. One time I couldn't even get it to pull itself in the shop. Did a short road test and shifts didn't seem very firm.
Adjusted bands according to TF3 instructions.
Just did pressure tests on front, rear, and line.
Testing the rear servo pressure, 1st gear showed 90psi, and reverse maxed the gauge past 400.

Line pressure test showed around 100 in all forward gears.

Front servo showed 90-100psi in 3rd gear only, and that seemed to flutter a little. Anyone have any insight of what I need to look for?
