I purchased the final TR-6 shortly after selling the Yamaha XS650. I still owned the Corvette at the time, but I really missed having a little sports car. This little Triumph was red.
The top and interior weren't in great shape, so I just left the top down with the cover over it (like in the above photo), and let the San Diego dew soak the seats. It was under a carport, so nothing got *soaked*. I kept an old towel behind the seat to wipe things down before going anywhere.
It let me down only once, and that was when the transmission failed. If I recall correctly, something had been wrong with second gear. My roommate was driving when it gave up the ghost. Neither of us was very surprised. I found another transmission, and this one had an electric overdrive! That made everything even cooler.
TR-6 transmission with overdrive. The two overdrive sections bolt on to the standard 4-speed at the right.
The new transmission required a little extra work, but it was worth it. I installed the new transmission and built a little electric circuit with a toggle switch on the dash to engage the overdrive solenoid. That solenoid is a little black cylinder at the lower right side of this transmission.
There are two electrical switches on top of the gearbox. One is to turn on the back-up lights, and the other is to prevent the overdrive from engaging unless the car is in 3rd or 4th gear. I guess the torque of lower gears would damage the overdrive unit. Anyway, I was really happy with that car, and kept it for several years, until I decided to get my first 4x4, which I traded it in for.
