Erratic torque converter lockup after new tires?
I found some posts related to torque converter lockup issues but they all referenced bucking and shaking. Mine does not do this.
What mine is doing occurs at lockup in 5th gear. It varies in firmness from hard to very soft. When the lockup is soft I hear the rpms change more slowly. I have an Edge CTS to watch it.
It started the same day I got 4 brand new tires (same stock size) but I can't see a reason that would make a difference. Coencidence?
The trans is original and the fluid was changed about 50k ago. I am using the tow tune from ID.
Thank you in advance
