This concern relates to vehicles equipped with the E4OD and 4R100 automatic transmissions. Fluid leaks from the rear of the transmission and excessive vibration felt in the vehicle while driving can be caused by a lack of lubrication to the rear of the transmission and rear seal failure. The extension housing (rear portion of transmission) can lose lubrication if the fluid supply hole becomes clogged. This leads to rear seal failure from lack of lubrication, and can cause bearing failure in the extension housing. The extension housing and gasket should be replaced and verify the fluid supply hole is clear of debris.Google+

was coming back from Tampa FL to Ga and i dont know what happened but i had been having a lot of vibration and then all of a sudden like some dis logged itself from the van then smoke smoke smoke from the back and fluids was leaking out like crazy. So we made it home but every 10-15 minutes we had to stop put transmission oil in it to make it go it was crazy. So someone said my rear seal came out so we put a new one in and it still not shifting well at all. SO i was gonna try to take the pan off and let it drain and get a new filter and gasket ect... and see what that might do but i wanted to know what it looks so if something looks funny i will know! Any help would be great!
