Does anyone know and care to share experience on what to do to the D or J type laycock overdrives to beef them for racing. I'm sure higher hydraulic pressures are in order but I don't know much beyon

I have been using the overdrive units fitted to the TR-3/4 gear boxes for about 3 1/2 decades. I am not sure if this information applies to GT-6 overdrives. Someone from British Leyland (Michael Bar

Bill, Thanks for the info... But could you explain the rationale behind this statement: I assume this is to mean use the 4.11 instead of a 4.30 or 4.55 or whatever. Is that what you mean? regards, rm

I hope there are some answers to the question you asked. Seems to me the first order of business for any Vintage Racer is making the car and drivetrain as "bullet proof" as possible. That to me goes

I raced my TR4 in the Midwest for 12 years with an overdrive most of the time. I did use a regular 4 speed for a short time but didn't like it as well. The only problem I ever had was a few gasket le

Though at times it is a pain in the neck to get operating properly (or at all) the O.D. gives a BIG advantage in that you can have a selection of gears (make that 2) for almost any corner. Getting th

There is nothing inherently unreliable with the Triumph A-Type overdrive. In 24 years of racing with one, I never once had a mechanical failure. I was using an overdrive when I won the runoffs in 199
