SUCCESS!!!!! Put this baby toooooooo bed!

I timed the procedure. From the time I started collecting the necessary tools, to coming back inside to sit down and pat myself on the back, 2.5 hours.

I yanked out the valve box again, split the box, changed the Governor Pressure Boost Valve spring back to its original position...in FRONT of the governor, put it all back together...then test drove for about 15 minutes dialing in the Bowden Cable....

This tranny now shifts better than it ever has. Yes, there is still that too quick a shift from 2nd to 3rd, but now it is happening at about 500 rpms higher, which feels much more comfortable in the existing power band of the car.

Not only is my tranny working normal again after losing 3rd and 4th, but now it shifts better overall.

Happy Camper!
