General Tech Overdrive--Afraid it's Serious

[CJD]

As for the clutch and OD...it is not necessary. That said, I always clutch, as these gearboxes are not Muncies, and they are very old at this point. Anything you can do to minimize shock loads should go a long way to a problem free lifetime. Back in the day, I would literally bend shift linkages jamming Muncie's into gear, and the boxes loved the abuse. These Triumph boxes are not nearly as robust, and appear to be designed right on the limit of "minimal".

Agree!

Here's another way of shifting in and out of Overdrive

I tried OD on my TR3 for the first time yesterday and it was SO COOL (especially since it worked and engaged/disengaged without any hesitation).

Thanks Ken for posting the link to the instructions. "Feather the throttle when engaging" and "give more throttle while disengaging" makes a lot of sense and will be my mantra -- next time!

I never lift to go into or out of overdrive. I just flick the switch.

In the 3 I had in the sixties, I didn't have the lockout switches wired. When I was street dragging, I would cut in the OD at the end of second gear, foot full on the throttle. Getting 18% of the revvs back really impressed the guys in the other cars. Talk about close ratio gears. Never did it in first, of course.
