No reverse...

Hope to get a helping hand here... Have a 68 dart GTS, 727 torque flight, cheetah manual reverse valve body. Car's been sitting for a few (5-6) years. Just brought her back to life, and have no reverse.

Dropped the pan and valve body. Manual pressure test on rear servo seemed fine. Manual pressure test on front clutch apply port using 90 psi resulted in air and milky trans fluid coming out of rear clutch apply port. No thud of clutches heard. Hmmmmm.

Normal? Front clutch malfunctioning?

Thanks guys....
