I think your mechanic said 75w-90, and that is readily available and the factory specified lubricant.
Just know that you can't readily refill a transmission that has engine oil in it with gear oil. The gear oil will not break down the film of engine oil on parts and can lead to premature failure. You need to flush that thing out fully before changing from engine oil to gear oil.
And, quite honestly, I don't see the point of changing lubricants if your transmission is happy the way it is. There is no evidence that one works better than the other or will help keep the transmission alive longer. Unless you've a specific reason to switch, don't.
