I guess the question is a bit vague Maybe I should say How much does a (good) converter slip at wot at 100MPH? Then again how much does a (stock) converter slip at WOT and 100MPH? Just looking for some numbers to play with to determine my final gearing. Car is my Duster Don't know the aero (drag?) for this car Torque converter slippage has a lot of variables like was stated. Weight of car, torque output, rear gear ratio and even trans fluid tep/viscosity all have a pronounced effect on slippage. For instance, our car weighs 2950 and has right around 2500 HP. If we run a 4.10 gear our converter slips about 12%. If we switch to a 4.22 and do nothing else it slips at 9-10%.
