The Toyota manual says GL4 works i will double check that...Well crap, the store is an hour away but don't want to drive my truck without looking for metal in my fluids after that scary sound I heard.
Auto trans already done. My truck is TRD locker not LSD. I put MT90 in my 2000 TRD locker rear diff without problems but I'm always open to suggestions and can always learn. Better here than with my truck.
