OK, I have a stupid question, and I know the answer is in my books, but they are at home, and I am at work. '64 TR4, OD transmission, what weight of oil goes in the gearbox? I want to pick some up on the way home... Thanks...

I use Valvoline 20W50 VR1 racing oil and I like it - non-detergent is important. I think 30 wt straight is also used successfully - though I tried buying cheap 30 wt non-detergent and that was a big mistake as my od stopped disengaging. Pretty sure the VR1 also has ZDDP so you can just run that in the engine too. And its great for salad dressing. Okay the last part is made up.

I'm in agreement with the Valvoline VR1 in the O/D trans and I've used it for 10 years in my trans. It is non detergent which is what you want in the O/D. Unless you change it very, very frequently I wouldn't advise it in the engine for the same reason, it is a non-detergent oil.

I'll third the Valvoline Racing 20W50. I've used it myself for many years, and it works well.
I also used to run straight 40 weight Valvoline Racing in a previous TR3A engine (back before it was called VR1) and it worked fine as well; except that the oil pressure went kind of high at first startup in freezing weather. It's not non-detergent, just low detergent. The detergent just keeps dirt from settling out in the pan anyway, not such a calamity IMO. It still kept the pan far cleaner than the cheap detergent oils I had been using before that!

Keep in mind that gear lube and engine oil have weights contrived under very different systems... thus 90 wt gear lube is roughly the same weight as 30 wt engine oil.
FWIW -- I use Valvoline 30W non-detergent oil in the OD gearbox.

Same here 30 W Valvoline
The TR manual did specify 80 90 for the trans reguardless of OD or not.MG said 50 non-detergent.G.O.K.what the engineers might pick today from the long list of vastly superior lubes that have since come along.....I like a nice 70wt with a dash of Lucas stabilizer(no olive,shaken,not stirred).What ever goes in,will look much the same when it leaks out.....
