Not recommended.
In a pinch, use synthetic 5W-30. Yes, that's right...motor oil. But make sure it's synthetic! No naturals or hybrids!
GM Synchromesh is actually 5W-30 with special additives specifically for transmissions.

Most any 90 wieght gear oil. If you have any problems, switch back, but really, any 90 weight oil will work, or ATF is better than nothing.

Do you mean something other than 85-90 gear oil?
No.

However, ANY oil is better than no oil.
