Lost me Mike. What do you want?
Down shift a 4 spd definately helps keep things brakes from overheating on the steep declines.. Even with a torqueflite, 2nd is good for that if the speeds aren't too high.
If you're getting fade, whether its brakes or drums; fresh brake fluid is number one, then find a more appropriate lining material for whichever end is smoking - or both. Some of the stuff sold for us in the parts stores is pretty sad - especially for the rear shoes. If there's no lining shops near you, Rochester Brake & Clutch is an option. Do you know the second letter on the edge code is the 'recovery' rating? if not, I've got run but here's an overview Brake Lining Edge Codes | Corners Are Best - Handling Tech | Moparts Forums
