Or should it only be used in LSD?
Not sure cause I think they also make a tranny specific oil? Synchromax I think its called.

Ya im runnin the 80w90 in my manual trany and diff in my 89 turbo. I also work at a lube station that sells royal purple. the syncromax is for the limited slip. Helped alot my diff was slipping now it locks like a champ

My diff is fine, was gonna change it with the tranny fluid just for the hell of it.
I looked into this more, I was gonna buy the Max-Gear 75W90, is it ok to dump that into both LSD and Tranny? Or should I put the Max-Gear in just the LSD and the SynchroMax into the Tranny?

its ok to use in both
