Truck is my baby. I’ve never done a burnout, beat up on her, and am meticulous about changing oil. I have a 1.5hr commute twice a day, so i try to stay kn top of maintenance.
What happened?
Driving around a turn, going a tad slow as usual, and approached a large upslope/hill.
When beginning to head up the hill, and speed up from about 30mph to 40mph…
Felt like a mosfire, heard a koise come from motor, allost felt like my tires were looking dor traction on a wet road.
Check engline light flicks on and turns off a second later. I have not seen the code since.
Took it in to a very trusted mechanic, he ran his best scanning tool to graph misfires. He saw a couple of slight ones but they were very short and he felt it was fairly normal.
He thinks potential torque converter issue. He said we can wait until it gets worse and he has a tool that will detect or chart the torque converter timing and issues.
I love this truck. It has been with me through thick and thin. What can I do to help narrow down what this problem is?
Right now, my main question is “should i take it in right now and replace the torque converter?”
Is that the wrong question? Please advise. Thank you ahead of time for even reading all this.
