I've got a question that's come up due to being an idiot. I bought a BB tranny and transfer case about 3 yrs ago, and I am finally installing this weekend. The guy I bought it from had rebuilt it and sent half a bottle of the fluid along, after 3 years and 4 moves...I naturally lost that bottle. I remember that it was not tranny fluid that he used, but that is all I remember. The old stuff is red like tranny fluid, but....I just don't recall. Is anyone else out there using something different? Any suggestions on what is the best stuff to use right now? Thanks for any help.
