Looking to change fluids. For the rear differential the owners manual says “models equipped with Trac-Loc” require an additive. The build sheet shows “Command-Trac Shift-on-the-Fly 4WD”, I have a few questions listed below.
Jeep is 2007 Sahara, 3.8L, automatic transmission, 3.73 gears.
1. Is command-trac the same as Trac-Loc?
2. If so is the additive required regardless of towing status?
3. What is the additive required? The OM doesn’t say, just says additive, unless they are referring to it being “synthetic”.
4. I suppose you could use the fluid recommended for trailer towing even if you don’t tow very often?
