You torque converter constantly allows slippage. The harder you accellerate, the les slippage you get. The slower you accellerate, the more slippage it allows. Once you reach a certain speed, you torque converter "locks up", and doesn't slip any more. Once you slow down, the torque converter "unlocks", and starts slipping again. This is the way it's designed, to promote fuel economy and longevity.

But it my case, and probably in your case as well, your torque converter does not "unlock", therefore when you're sitting at idle your torque converter is locked up and won't slip, causing your car to stall. Intermittently it will go into gear fine, but more often than not it will stall when put in gear if you're not giving it gas at the same time (ie: neutral drop ).







I just wanted to say that that is probably the best, concise explaination I've heard for how an auto works.

I hope you dont mind if i use it to explain to my non-mechanically minded friends.
