I wouldn't like to be working an old Inter without the TA though.
Not the oil? Not that I care if anyone believes, but I can say I watched an old inter destined to be a pull apart job, (as it had to be towed back to the shed because it wouldn't get there under its own steam) ... getting back to work finally with "better" oil, ripping hard, as well as sticking in the higher range of gears without the slightest hint there was any problems with the TA. Proof of the pudding is in the eating I say ... it could have just been sheer coincidence, but what are the odds.
I've even pointed out the oil / TA issue to various farmers after noting their old girl was starting to slip and the oil they were using ... but most were adamant they'll stick fast to the hydraulic transmission oil, that's what their oil guy told them after all ... etc.
