1961 to 1980 Power Sunroof Cable Transmission Drive Unit Service and Repair - On Demand Video

Covers theory of operation - complete service and repair, and installation tips of this critical unit. Part 2 of Broken Sunroof Series

The sunroof transmission drive unit moves the cable back and forth to open and close the sunroof. There are 5 gears inside this unit that transfer the incoming drive from the motor ( high speed) to the final drive moving the cable (slow speed). If this unit becomes over stressed due to lack of lubrication in the sunroof panel mechanism gears can break or strip or the cable itself can be damaged.  It is VERY important that this unit be inspected and properly serviced just because it NEVER gets done - even by so called professional mechanics.
