I drive about 25% city 25% highway and 50% country. Country driving is long two land roads with minimal stops at about 55 miles an hour. Just put the trans in finished it Wednesday so it only has about 100 miles since I put it in if that. No Power upgrades have been done engine is almost stock the only thing I have done to the engine is took off the muffler and made it straight pipe 3inch exhaust. K&N air filter system no air box tire size is 285x75x16 stock gears. As I said before I have added a good aftermarket trans cooler and today I checked the trans temp and it stayed around 155-160 with my driving
