If you have been running steel sealing rings the snout on your pump is probably worn and contributing to the low pressure issue. The first thing to go will be the band will burn up in less than 10 runs. If you notice the car trying to back up when you get on the brake then the band is starting to burn up. This is what was wrong with my car several years back. Coan turned me on to a new pump and valve body and I started using the Teflon seal rings. Coan set my line pressure to 170. I would replace the pump and have a good trans builder like Coan rebuild your valve body. The Teflon seal rings work real good and eliminate the wear in the grooves on the pump snout.
