Main line on the 47re is not over 115 in forward gears at idle. They run lower in the area of 65 on the low side and over 100 psi at max TV input.
Reverse will run higher at near 250 stock and higher if you install a shift modification kit. The kit depending on how the tension on the PR
spring is adjusted will raise all pressures.
You mention a blocker rod. Where and why was this rod installed?
There is a port on the rear servo and front servo. Have you installed a gauge there?
