Hi l have an E36 Automatic BMW which has a continuous gear box problem. l had it flushed which fixed the issue for a couple of months. Now it is slipping again. Can l add Trans Tune to the oil that is in the gearbox now? l don’t want the expense of replacement oil again .
Yes, Sea Foam Trans Tune can be safely added to the transmission on your E36 Automatic BMW. From my research, your BMW transmission uses Full Synthetic Automatic Transmission Fluid(ATF). Trans Tune is compatible with all Conventional and Synthetic Transmission Fluids. You have nothing to worry about.
