[QUOTE="Lil ugly, post: 1571128, member: 3188"] I am not knowledgeable as to the parts that you need to upgrade on the 700r4. Heat is always the biggest killer of auto transmissions beyond a poor set up. 160 to 180 is not bad for that transmission. The RPM range depends on your engine and gearing, it helps align tranny lock up with your vehicles powerband. A stock truck is usually in the 1800 range, you will likely need to stay in the 2000 to 2100 range. Remember though the higher the stall the more heat you will develop. A quality torque converter is a must for keeping your tranny alive. Hard to put a time on how long a tranny will survive in this sport. Depends on too many factors, like heat, fluid changes, quality of build, how hard its beat on, how often it gets used etc. Definitely stay away from Monster transmission. I have had good luck with my parts from TCI but have never bought a tranny from them [/QUOTE]
