700r4, 37\" tires & 3.08s With the 700r4, I'm running 37" tires with what I'm pretty sure are 3.08's. I really can't afford a gear change or an aftermarket cooler right now. Is it safe to drive with this setup or am I killing my tranny quick. I'd say I'll be able to replace the gears in 6 months or so, but am I gonna kill the tranny before then? I'm just wondering how much extra heat is actually produced.
