I had planned to change to the synthetic, but a truck shop specializing in heavy duty Allisons told me not to waste my money. They said they don't use the synthetic because it is so expensive and they haven't seen any benefit.

What gives with all of these really expensive ATF's? The stuff required in the new Jaguar's is $20.00 or more a quart.

Thanks, Loren
At 20$/qt, how many qts go in an Allison 3000 series transmission?
