How to Check Transmission TR3 Fluid Level

The Triumph TR3 is a British car produced between 1955 and 1957. It is equipped with a four-speed manual transmission. Checking the fluids every few weeks is a crucial part of regular maintenance. If fluid levels are too low, it causes the gears to grind together in the engine. Once transmission fluid gets old (approximately 30,000 miles) debris begins to build and cause engine damage. Checking the transmission requires a few standard tools and can be completed in less than 20 minutes.
