If it's the main seal then it will require the removal of the transmission. Once it's off then you'll be able to remove the rear plate seal (P/N 102023) it's installed in. The plate is held by 5 bolts. After taking it off you can then press out the old main seal and press a new one in (P/N 102024). You will also need a new rear plate seal gasket (P/N 102022). Hardest part is getting to the damn thing. Changing it is cake.
