Forward drum procedures are almost identical. No center seal to worry about on a TH350, it typically already has a 5 clutch pack, except light duty applications. | Forward drum procedures are almost identical.

Forward clutch pack clearances can be tighter than usual, however it must have some clearance. If too tight it can creep in neutral. | Forward clutch pack clearances can be tighter than usual, however it must have some clearance. If too tight it can creep in neutral. | ||

− | Pay attention to this | + | Pay attention to this polished stub of the input shaft, it goes into the bushing that is in the end of the out put shaft. It is a high wear area. Be sure it is smooth. Minor scoring can be smoothed down. |

Notice the scraped and split low reverse friction in the intermediate piston cavity. This slightly tightens the intermediate clutch clearance to achieve cleaner 1-2 shift. | Notice the scraped and split low reverse friction in the intermediate piston cavity.

Pump gear install. Note the orientation of the tangs on the inner gear. They are offset. They should face away from the seal. Mis-installation will result in pump failure and converter damage. | Pump gear install. Note the orientation of the tangs on the inner gear. They are offset. They should face away from the seal.
