I have an aod transmission that I am rebuilding and the planetary gear rear bushing was damaged and I had to remove it . I marked my bushing to the depth that the old one was in , but I don't know for sure that it didn't move when it went bad . My torque converter had ballooned and I didn't know if the direct drum ( damaged too ) could have moved it . Does anyone know the correct depth to set it or how to do part clearance checks once it is installed ? I also had to remove the pump bushing . I noticed the bushing there was sticking out the front the same it was sunk in on the inside , so I beleive i'm good there but if anyone knows the depth let me know please ! Also I read that some of these need machining afterwards , but I was told you could lightly file and sand any burrs you put in it .
