C3 Chevrolet Corvette Transmission Oil Cooler Line

C3 Chevrolet Corvette Transmission Oil Cooler Lines

Even for those lucky enough to have multiple ‘Vettes in the garage, nothing is quite like the C3 Stingray. Third-generation Corvettes are stylish inside and out, and the V8 engines in these vehicles have a deserved reputation for exceptional performance.

It’s important to care for vehicles from the past, and that includes your 1968-1982 Corvette. One system that often gets ignored is the transmission oil cooler. A failing transmission can lead to a costly repair, so it’s best to purchase all-new transmission cooler lines if it’s been a few years since your last replacement. At Top Flight Automotive, we have all of the transmission components you require to keep your ‘Vette on the road, and we get you the lowest prices too.

The Purpose of Corvette Transmission Cooler Lines

All vehicles are equipped with manual or automatic transmissions, but automatic transmissions put extra stain on their fluids. All 1968-1982 Corvettes have factory installed automatic transmission oil coolers built into the passenger side radiator tank. When you push your C3 Corvette, transmission oil cooler lines take coolant away from the transmission to the radiator to ensure it stays at a safe operating temperature. 

Transmission cooler lines are made of heavy-duty metal, with short rubber lines making the connection from the frame to the radiator.

When Should I Replace Transmission Cooler Lines?

Stock Corvette transmission cooler lines last for years. However, the C3 generation has been out of production for more than three and a half decades. Your model could show wear and tear under the hood depending on the maintenance it has received and the conditions it’s exposed to.

It is best to assess the state of your C3 transmission oil cooler and its connections regularly. You require all-new transmission cooler lines if the indicators below apply to your 1968-1982 ‘Vette:

  • Your vehicle’s cooling lines are bent from impact.
  • You discover ATF leaks below your C3 Corvette.
  • Some of the fittings between connections are missing.
  • There are noticeable delays when shifting gears.

The key to keeping your C3 on the road is to be proactive with transmission cooler line repairs. Tackling restoration tasks before you smell overheating components can save you from a complete transmission swap.
