Tranny Fluid

First I must tell everyone how helpful this forum has been to me. You all have been so great in offering advice to me, not only prior to the purchase of my '64 BJ7, but also since then, with my numerous dumb white-collar questions!
Although I bought my first British car in '68, (a'57 MGA), I never became a wrench-head, and only performed a little transmission work on gear changes and other minor work on the car prior to running it into the ground, while driving to and from college in western PA.
I checked my transmission fluid today and found it to be low. I then went to the local auto parts store only to become totally confused. I was told by the shop that did my initial work after my recent purchase, to use a 20-50 weight fluid, but the store asked if it was fluid or gear oil?? Heck, the shop just said to get 20-50 fluid?? Is it oil, fluid or what? When I called the shop back for clarification they said they didn't know, and to smell it to determine if it was gear oil,(a bad smell), or just transmission fluid, which doesn't smell bad, and should look reddish in color. Well, it doesn't look red, but rather a brownish color, and doesn't smell like a gear oil! To top it off, the clerk at the auto parts store said the gear oil would not smell if it was old!!
So, I guess now I should just drain it all out and start over...but with what?? The original owners manual has specs for all of that 50's and 60's stuff, but what do I use?
And once again, thanks in advance for your great assistance, and hopefully one of these days I can pass it on to another neophyte like me!

P.S. Am I the only person that just can't understand why people can work in a store,(any type of store,)and have no concept of what's going on other than scanning a price, having the cash register tell them how much change to give back and then program them to say thank you and have a nice day?

The AH factory recommendation is SAE 30 motor oil. I have read at least a dozen suggestions ranging from 20-50 motor oil to exotic specialty oils. I believe that Triumph recommends gear oil for the same type of transmission. I don't think that it really matters very much what you use.

Hi Langloth why don`t you just drain the tranny and refill it with 20w50 motor oil and have a ball. I have that in both mine and they shift like silk. Skip
 
The factory recommendation for the rear axle is SAE 90 hypoid gear oil. Some people use 80-140 hypoid gear oil if the gears are worn. Either should be fine.

Langeloth;
Yes, the rear axle can use 80/90w gear oil.
As others state, 20/50 wt motor oil in transmission.I just changed my trans fluid, and while it was drained, removed the drain on the overdrive unit and cleaned the screen in lacquer thinner. It was pretty gunked up. Check and grease your ujoints and front yolk of driveshaft while you are down there.

Take a look at page 3 of this forum, see Redline Oil topic. While I am not an expert on trans oils, I am currently having my clutch and synchros rebuilt, and will use redline in the tranny when complete. Hope this helps.
 
Langloth,

I am using Redline MT90. I cannot really tell if this exotic expensive oil is making a difference or it is the placebo effect. I may have more feedback after today's run to Carmel By the Sea. Supposed to get to 80 degrees here. This will be the first time to try it out with OD. I am using it since like you I completely drained the thing not knowing what was there from PO.

No, you're not the only one who gets frustrated with ignorant sales people. I've encountered this at auto parts stores, appliance stores, hardware stores and grocery stores, to mention a few. The knowledgeable sales people are a thing of the past. They have been replaced by mere money collectors. Enough of that; while I haven't had my Healey for very long, I,m running SAE 30 in the transmission and no problems.
 
I am now running snthetic Redline MT90 and am very happy with it. I haven't put a lot of miles on it yet, so it could be placebo effect.......but it does seem to shift nicely, operate quietly and all that. I also put Redline synthetic in the rear end. Concerning store clerks: I was so very pleasantly surprised the other month or so when I was looking for a tool to separate the ball joints on the idler arm. Anyway, the only sales clerk that was available was a very young lady. All the stereotypes were shattered when she proved to be extremely helpful and knowledgeable. She sold me the right tool and gave me tips on how to use it. The lady couldn't have been over 25. I hope this comment doesn't offend anyone, but it has been a long time since I had good help at a chain car parts store and really was very happy with this young lady. I do plan to return to that store.
