[QUOTE="Chris Crampton, post: 700038, member: 14917"] Exactly. On streets and highway it will not make too much heat just cruising, but apply any load(ie, hills, towing, rock crawling, uphill sand washes, etc.) you would have to be "coupled". Meaning that you would need to be out of the Tq multiplication or stall region to dramatically reduce the heat created in the converter. The main reason for higher stalls is some high performance engines need the slip at the bottom end to allow the power band to ramp up quickly and couple were the engine starts to build its real power and torque. It can be done, but under certain situations you'll have to drive the truck sporty to keep the heat in check. Also driving the truck harder will add heat in engine coolant and oil. For example, in our race cars we have converter in and out temps with psi sensors. This is so we can drive the truck accordingly to what it needs to keep it happy. This topic can become very complex. Sorry for the ramble, I'm drinking. Cheers. [/QUOTE]
