Had to replace input shaft Seal on the Mazda Dog.
13mm bolts, cover comes off. There is a metal sleeve on the bottom and upper has a seal. NO gasket, just rtv held it on. Removing the seal you need to punch it inside towards trans, not outward like an engine seal the flange on mine chipped as it was to late but only a small bit.
