This is probably one of the best transmission fluids I have ever used in a vehicle that I tow a 5200 lb trailer behind my Ford F1 50 4x4 and there is no slip, no friction fluctuations, nothing. I tried other transmission fluids when towing this trailer and they slipped and cost friction. This transmission fluid I purchased from Revain was rated five stars, best in class, would definitely highly recommend to any buyer or anyone using a car filled transmission fluid.
