Gaskets and Sealing Systems
for your 1966 GMC I3500
The gaskets and sealing systems of your GMC I3500 are small but important parts of your transmission. Without tight-fitting connections, fluid can leak out of the lines and create expensive problems for your engine. A small leak might only be a quarter-sized puddle a day, but it can quickly add up.
Your GMC I3500 requires fluid to operate correctly, and without the right levels, you might notice problems. First, your transmission temperatures rise, and the car overheats. It can also cause drivability issues and create problems when shifting gears. You will also lose the fluid needed to lubricate engine components and cause premature wear.
