DTC P0700, TCM Malfunction
Just got home from overseas for 6 months and I have a few questions. $20 bucks to the first person that can help me out.
The truck sat for that time and the wife did start it every few weeks. I have a trouble code right now that is DTC P0700, TCM Malfunction according to my predator programmer. Can someone please help me out with this trouble code? I will put the truck into gear and it seems to fall out of gear, making a clunking noise.
Any help would be greatly appreciated.
On a side note, I was thinking about some performance upgrades, but this trouble code has me worried. I was curious about torque converter upgrade or a valve body upgrade. I would like to add an air take in would like to take any recommendations.
