You unscrew the transmission temp sensor and hook up the pressure tester there. Then get the engine up to operating temp read the pressure at idle in park?Then idling in park pull the line pressure fuse what is the pressure now?Then put the line pressure fuse back in and restart the engine. Then at idle put the transmission in reverse while watching the transmission pressure does it go up fast or delayed?Also what is the pressure reading at idle in reverse?Now put it in drive what is the pressure reading?Also what kind of scan tool do you have?

The line pressure fuse is right in the under hood fuse box labeled LP if memory serves correct. Get me back the pressure at idle in park with the fuse in and with the fuse out. So far sounds like the pressure regulator in the valve body is bad.

The 8th digit would be two numbers back from the TZ?

Also with your scan tool can you buzz the transmission actuators?
