Torque converter.
2005 La Crosse. Do these cars have a lock up torque converter? Can it be disabled?

Re: Torque converter.
At low speed and low throttle it seems that the torque converter is locking up and then unlocking. is there a switch on the brake pedal like was first used that you needed to apply the brake to shift. I just had the transmission flushed and it is working better ,but not this hard lock unlock. Is there any vacuum from the intake to the trans control? Thanks

Re: Torque converter.
No vacuum, all electronic controls from the pcm. To avoid unnecessary repairs you should have it scanned with the proper bi-directional scanner to see pcm commands and tcc functions.

Re: Torque converter.
Before you just go disconnecting the tcc you should really be sure that's the problem. Converter lockup shouldn't be that noticeable of a difference and you will have more problems if you bypass it. Can you describe your problem in a little more depth?

Re: Torque converter.
Are we talking about the TCC engaging/disengaging, or about harsh shifts?
Have you scanned for transmission codes? |
