GL4 Manual Trans & T-case fluid S1 their compatibility or performance withMeets & Exceeds Roxor OEM specifications, Cen Pe Co Lube is our fluid of choice. This is a 80w90 lube with Temp Tac. Temp Tac is an additive which bonds to the metals and creates a "coating", this is important for slower moving vehicles and vehicles that may sit for a few days. This is for 1 gallon as your Transmission calls for 2. 1 Quarts and your T case call for 1. 7 Quarts, so 1 gallon is all you need! GL4 Manual Transmission and Transfer Case
