This is what happen, coolant had leak in the trans and I still drove it for a few more day before I parked the car for a month, and now I just finish installed new radiator and flux the trans with two case of Dextron III plus new filter.oil look good and red now.
I drove test for a few miles, and now it start lock up every time I put in reverse.Look like the reverse and first gear they are locking at the same time when I put in revers or D.When I increase the acceleration it roll for a few feet and when I release it stop like braking, and when I put in N mode the car still roll forward like it still in gear.any one know of this type of transmission problem?
BTW just did new fluid, new filter,up shift cable adjust,shifting link adjust,brake and E brake not lock still the same, I was thinking some thing have to do with the reverse piston (B3 friction plate)in side the trans and or B2 band both too tie cause of water, or Valve body stuck. any Idea? Do you guys have any opinion that I can fix or adjust some thing without dropping the trans.thanks guys help me please..
edit it is a 722.351xx trans.
