Got a chance to pull it back in the garage this weekend to try to figure out why the o/u shifts into under when you move the shifter to over. Put the pressure gauge on both the direct clutch port and the overdrive clutch port and both read 195psi when shifted into their position. Both go to zero when shifted out of their position. Under works perfectly, and direct works perfectly, but when you shift it into over (linkage is working properly), it shifts itself into under drive. Troubleshooting matrix in the book suggests that I have a plugged port somewhere in the unit, but I sure can't seem to figure out where.
Should I try taking oil lines off and blowing air through everything just in case something is just plugged up?
