Considering my gearbox and diff are worth more then the rest of my car, its probably a good idea a give them an oil change.
What are peoples preferences?? how much do they usually take ??
oh by the way my gearbox is a TRD close ratio T50 and a TRD LSD in the diff.
i like penrite hypoid gear oil in my box, and penrite limslip in my lsd....ive always used penrite in my cars and its all proved to work well so ill reccomend them.
