    I have a 99 Silverado and been plowing with it since it was new. It has about 90000 on the clock now and I haven't had any tranny problems. One of the precautions I take is I change the tranny fluid and filter every year and I also run Amsoil synthetic ATF.

    If you have the secondary cooler that mounts in front of the radiator/condenser then I would say yes, it is enough. If you have that cooler then you should also have a temp gauge, so you should be able to tell if it is working.
