Hi all, just curious if someone that still has an owner's manual or a tech manual might know if there's any specific or special kind of gear oil I should use for the transmission and differential. Is regular 90 weight gear oil appropriate?

Thanks, Chris

Chris, In the 5ktq, it's GL-4 in the transmission, and GL-5 in the rear diff - mixing up the two will damage the brass synchros in the transmission. Searching

comes up with: According to the Bentley, the 4kq transmission takes SAE 80W or 80W/90, GL4, and the rear diff takes SAE 90, GL5. HTH, Cheers! Steve Sears
