TH400 Kickdown Switch - The 1947 - Present Chevrolet & GMC Truck Message Board Network

mclairmo · 08-20-2009, 06:09 PM

I am running a Th400 with no kickdown switch. Is this ok? I cannot find any solid info on whether or not I really need it. Some say I need it or I will burn up the trans. Some say it is fine without it. Not racing the trans and not towing. It's used lightly. I know B&M and Lokar make kickdown switches but I am considering using a nitrous full throttle micro switch mounted to the carb to activate the kickdown switch at full throttle but don't want to go through the trouble if I don't really need to do this. Any insight?
