Gaskets and Sealing Systems
for your 1955 GMC PM253
The trans components - automatic is an assembly of parts in your GMC PM253 that supports the ability of the motor vehicle transmission to automatically change gear ratios while the vehicle is in motion. The gaskets and sealing systems provide efficient fluid exchange within the system, a critical feature for avoiding a transmission burn-out.
The gaskets and sealing systems of a GMC PM253 are crafted from durable materials that can sustain continual contact with transmission fluid. Leaks or holes in these elements create a loss in pressure and fluid, things which ultimately affect the ability to shift gears. Without repair or maintenance with parts from StockWiseAuto.com, you can destroy the transmission.
