Need some help with a trans problem. I picked up my 05 about 2 months ago. Truck has been flawless and has shifted buttery smooth since the day I got it. Last week when I was driving in town the Tow/Haul light flashed for a few seconds and I had like one kinda harsh shift. The light went out, never came back on, and the truck shifted as smooth as it always had.
Today is the first day I've drove it since last week and my problem returned only it stayed on (luckily I only had to drive it a few miles). Here's what it did today:
1) A few seconds after starting the truck, the Tow/haul light started flashing before even putting the truck into gear and I noticed the idle of the truck was a tad bit higher than normal
2) I noticed a bit of a clunk shifting into drive or reverse
3) When I take off from a stop, the motor revs up completely normal, but the truck feels like it's stuck or starting off in 2nd or 3rd gear
4) First shift seemed to be one harsh shift, second shift seemed like it bucked for a second before harshly shifting into the next gear. Once in the proper gear it runs fine.
5) When coasting to a stop the downshifts were pretty rough
When I got it home I check for codes with my torque pro app and it came back with:
P0742 - Powertrain
- Torque Convertor Clutch Circuit Stuck On
The truck has a Banks 6 gun tuner, but the last time the previous owner had it in for a repair, the dealer disconnected it from the pcm, so I'm assuming that shouldn't be a factor..
If anybody could help me out I would really appreciate it.
Thanks
