It also have some suspitions that this is also not mechanically working because even though I felt some acceleration, I didn't feel that usual 25-40mph jolt or even as much of an overal jolt I use to get when when the "Power Mode" light turned on. It also could be me being a bit paranoid.
I know there have been some past posts on this subject but I just feel like I want to bring it up a new, so there are less pages to shuffle through and there may even be some new findings.
So do you think it is a TCU or mechanical problem? |
Does the light come on at all? when you start it ?
The TCU gets the message from the throttle sensor, when its 'rate of change' exceeds a set value, and just uses a different set of look-up tables, for shifting. Can't see what could go wrong, maybe,,,,,,don't know.
