pablo1b Posted May 26, 2006 Share Posted May 26, 2006 I saw in the jap subbie page that current legacy EATs have a torque converter lock (that would be a clutch that locks que torque converter). I guess this means that depending on how you rev the engine while up- or downshifting with the sportshift you could get better acceleration, sort of the syncing you manually do in a MT when changing gears with the clutch and gas pedals. Am I correct? Any tech insight on this? Link to comment Share on other sites More sharing options...
deneb Posted May 26, 2006 Share Posted May 26, 2006 Locking torque converters have been around for quite some time, 10 - 15 years or so. IIRC, it means that the converter locks such that there is no slippage when cruising at a constant speed. This is why AT's are rated at similar MPG these days. Used to be a diff of a few MPG between AT/MT versions of the same car. Link to comment Share on other sites More sharing options...
Elec Posted May 27, 2006 Share Posted May 27, 2006 My 1990 Grand Am had a locking torque converter. It was also bad, and would lock up if you drove over 50 or so, then fail to unlock when you came to a stop, stalling the car and keeping you from restarting it for 5-15 minutes. Which made for some "exciting" driving. Link to comment Share on other sites More sharing options...
