[QUOTE="HAYNES OFFROAD, post: 809157, member: 2684"] Ive spiked my trans temp to 235° in the dunes running really hard on a 80° day with factory ATF. Once i converted the trans to Amsoil i havnt seen temps go over 220° in the same conditions/driving. 190-205° would be considered normal operating temp for our trucks. 205-225° would be expected during spirited runs. 225-250° would be extreme situations such as hill climbs, or hard desert running. Let cool as soon as possible. 275° is the absolute max, VERY temporary operating temp (such as a long hill climb), before you will considerably reduce the life of your ATF and trans. Let cool immediatly. At 300° you WILL damage internal transmission parts, including warpage of metal parts, degradation of clutches, and melting of seals. Transmission oil oxidizes, (forming varnish-like substances causing further clutch slippage and compounding heat build up) and transmission oil life is extremely short. If you see this temp, break out the check book. Every 20° above 200°, oil oxidation rate doubles. For EXAMPLE, say, at 200°, ATF life is 100,000 miles, 220° ATF life is 50,000 miles, 240°- 25,000, 260°- 12,500, 280°- 6,250, 300°- 3,125 miles.... And so on... Obviously those numbers arnt going to be exact and is only hypothetical, because every transmission sees differant temps on a day to day basis, as in one day, your trans will only see 195°, while on another it sees 220°.... Obviously a larger cooler with fan, would be one of the better ways to control trans temps a lot better. Couple that with some Amsoil ATF and finned/deeper pan and that would go a long way. [/QUOTE]
