KiltedBanshees93GT · 05-20-2004, 10:10 AM

I just swapped a new t-5 from 5.0resto, into my car, and I know that the majority of folks recommend ATF fluid instead of gear oil for the t-5, (mainly iirc because of the needle bearings) But mine came w/ gear oil in it, why would the factory put non-spec flid in their tranny? I just got the thing in, and would rather not have to change the fluid already, but....
Anyway, is gear oil that dangerous for the t-5? If I need to swap, can the gear oil and ATF mix in the case without adverse effects?

Sorry, but I've heard too many opinions,and need a solid answer.

Thanks for your help,

J
