Torque Converter Lockup

Cloud9blue · 12-10-2010, 01:51 AM

I started to drive the car in manual mode about a year ago, just because it gives me better control of the car without the hassle of third pedal.

But I just noticed that the transmission does not lockup in cold weather, when the car is still very cold. And because of that, it makes the whole transmission feel like a old "slush-box" automatic. Quiet annoying sometimes when you tries to accelerate. But it goes away pretty quickly after a 2-3 miles of driving, and feels perfectly fine after that.

Talked to the SA about this, but he doesn't seem to have much of clue what I am talking about. So I am just wondering if anyone of you guys with 6AT experiences the same.

Yes exactly the same here, when really cold it does not lock up for a mile or 2.

Same here with dct. Lately I start in D to give it some time to reach operating temparature, then everything is fine manually.

Same here, its pretty normal, if you notice it happen during winter, the summer time here in Cali never happens.

Its actually common on almost all cars until they reach a certain temp. Helps get a little more heat in the motor.
