TR6 5 speed conversion
Having an extra 2 cylinders doesn't mean you're getting the ideal motoring experience from your TR6. The original 4 speed gearbox is simply not designed for American highways, and the factory optional overdrive is rare and now very expensive to source. Fortunately, a conversion kit has been developed by the fine folks at HVDA to join the outstanding Toyota Supra 5 speed gear box to the TR6 engine. The thoroughness of the engineering of this kit is exceptional, right down to the use of the original Triumph shift lever. However, it's the first entrance ramp merge that will convince most people of the quality of this kit, not to mention the satisfaction enjoyed in the following years of use. After installing several of these in the shop, we believe that this conversion delivers the product that the factory should have produced when these cars were originally built.
