You have alot of choices these days. Amsoil Multi Vehicle ATF is one of them. Alot of the universal synthetic ATF will say that it can be used in place of LT71141. Just look at your local sources to see what is available.

I like Amsoil product alot. They do increase fuel mileage when you change almost all fluids to their products... motor oil, ATF, differential fluid, and the coolant booster (not the antifreeze... that's too much money).
