Synthetic oil in manual trans
07 Colorado. The owners manual calls for 75W90 synthetic in the diff, 89021-806(manual trans fluid) in the trans. Am pretty sure the trans fluid is not synthetic. What about using synthetic oil inthe trans.

RE: Synthetic oil in manual trans
synthetic oil is more money. It breaks down at a much higher temperature. It will usualy extend the change interval.
I use synthetic oil in everything . I think its worth the extra money.
