Re: special fluid needed for detroit?
The Detroit does not need any special fluid. My friend likes to put in a bottle of STP when installing new gears and Detroits. I'm going to put in a couple of bottles of Lucas Oil Treatment when I change the fuild in my Detroited diffs. I'm running it in the motor, tranny and t-case now. I'm really starting to like that stuff! Got mine at Nappa.
