68RFE Input Drum Assembly |

This video demonstrates how to assemble and air check a 68RFE transmission drum, specifically focusing on the overdrive and reverse circuits.

The video begins by showing the components of the Transgo RFE-PP ODHP kit, which allows for an extra friction in the overdrive section for increased clutch holding capacity. The video then explains how to assemble the drum, starting with the underdrive section. The underdrive section uses single-sided frictions and requires five frictions to be installed. The video then moves on to the overdrive section, where an extra friction is added using the Transgo kit. The video explains how to install the wave snap ring and the flat snap ring on the overdrive pressure plate.

The next step is to air check the drum to ensure proper clearances. The video provides the target clearances for the overdrive, reverse, and underdrive circuits. The video demonstrates how to use an air pressure gauge to measure the clearances. The overdrive circuit should have a clearance of 40 to 63 thousandths of an inch, the reverse circuit should have a clearance of 32 to 49 thousandths of an inch, and the underdrive circuit should have a clearance of 38 to 68 thousandths of an inch.

The video then shows how to adjust the clearances by adding or removing frictions. The video explains that running the clearances on the looser side is generally better as it allows for better fluid circulation and cooling of the frictions. The video concludes by showing the final air check results and confirming that all clearances are within specifications.
