Cadillac Buick Chevrolet GMC Oldsmobile Pontiac
Replaces Part No. 20225150 and Coupling 20614175
*The same unit is used on both the driver's seat and passenger seat.
FULLY REBUILT: Proper Parts has re-engineered brand-new housings for these units and we recondition the internal parts. We've been building these seat transmissions since 2006. Our new transmission housings are manufactured in the USA from extremely durable polyamide with fiberglass fill. The complete unit is assembled, tested, and shipped to you ready to be installed. Guaranteed for Life.
IMPORTANT, PLEASE READ THIS: This power seat system is an antique. It is not an amusement park ride. It was NEVER designed for continuous use. Continuous use will overheat the bushings and lock or break the transmission. Move it to the position you like and leave it there. Do not repeatedly hit the end of the track going back and forth, and up and down. Unlike modern power seats that have current sensing, limit switches, and constant position monitoring, these systems do not even have a rubber cushion at the end of travel.

Black, Red, and Yellow Driving Gear / Input Shaft
The 20225150 transmissions had a RED or YELLOW drive gear/input shaft, not a black one. It used a white plastic coupler. The seat transmission was mounted to the motor with a 1/8 inch aluminum spacer plate between the two.
The original transmission housings were made of nylon. They were white when new but became brown and brittle over time, and many have disintegrated. Most failures are due to the housing breaking apart. There is no new OEM replacement available for this part.
WHAT IS AN ACCEPTABLE CORE?
The internal components are what is important. If the outer case is broken and in pieces, that is not important. We just need the internal parts. If you have any questions, please contact us in advance or send a photo.
NEW COUPLING INCLUDED, PART NO. 20614175 L Proper Parts has re-engineered an improved coupling design that ensures a smooth slip fit to the motor and transmission. The D-shaft openings are very accurate. We manufacture these couplings from a urethane chosen for its hardness and toughness while still having good flexibility. When the seat comes to the end of its track there is no cushion, and this coupling allows the motor to slow down gradually ensuring a longer life for all of the components involved. It is much better than the original.
