get a big trans cooler! heat kills auto transmissions!
yup, but really a trailer with brakes would be better. it will be a load, but it will make stopping easier.use caution when flat towing, if something in the drivetrain could be deprived of lubricating oil if the drive gears aren't in motion and throwing oil on the moving parts.
certain 4x4's can do damage to the tcase if they are flat towed, i think thats why mathster is recommending towing it with the drive wheels up on the dolly if you plan to go that route.
