My friend brought his TD over with no forward movement, and was told it had a bad B2 piston. He provided the new part, and I read a few threads on the subject. After removing the cover (real hard job with the limited space), I found the B2 to be in pieces.

I installed the new B2, and put everything back together. After filling up the fluid to the proper level, it still had no forward movement. I did more reading, and thought that maybe the bushing and/or seal was bad. I procured the parts, made a puller as described in another thread, and pulled out the old seal and bushing. I installed the new bushing and seal, making sure the seal was installed properly. After replacing the filter and gasket and putting everything back together, it still has no forward movement. It is kind of discouraging doing all this work with no positive results. Yes I did use grease to hold up the "dogbone" so it would be in the right spot on the brake band. Anyone know what could be the problem? Thanks in advance, Rich

EDIT: Reverse gear works fine, both before and after B2 replacement
