OK, valve body out...everything looks OK, whoever did the trans mods years ago took out the accumulator piston spring.No block rod. Piston moves freely...should I install a blocker rod?
Some other posts on other mopar sites said it's not good to just let the piston flop back and forth.Doubt if that's my problem, but will it hurt anything to add the block rod?
Guess I gotta gut up and clean the valve body and check for debris...this trans has worked great for a lotta years, don't understand why all of a sudden...
