<div>I always used the earlier A-Type O/D (with the large accumulator) in my race car. Raced for 24 seasons and never had an O/D mechanical failure. It is a verry stout unit. I'm not sure the change took place with the introduction of the 4-Synchro box. I think some of the large accumulator overdrives I used came out of early TR-4's. I'm pretty sure all of the TR-4A's had the later design with the smaller accumulator.<br></div><div><br></div><div>Jack<br></div><div><br></div>

I tried to separate the rear OD housing from the main OD housing after removing the rear output flange and speedo drive. Once i removed the 6 nuts and washers, I had to tap the studs with a brass drift to get the rear housing to separate from the main housing. But now i can't get the rear OD housing to come completely off. I can get about a 1/4" gap between the rear and main housing but it won't come all the way off.
