I have a Craftsman tractor, 917.275821, that I have worked on before for the tranny not going into reverse. Last time I just cleaned the linkage and tranny area and it was able to go in reverse. This time I cleaned everything but it will barely go into reverse...(creeps). So, I tried to adjust the two bolts (B) & (C) for the shifter doesn't want to go back in the reverse slot hardly at all. It appears by the picture that there is a little tab (A) that wont let it go any farther in reverse. How can I get this tractor to go into reverse again??
