Limp mode

[pwesley]

Ok guys. Need more help please. Changed obd2 port. Finally scans now. Got code p1886. Changed the a, b, and 3-2 shift selinoids. Cleared codes. Start truck and drive. Goes into limp mode. Stop. Shut truck off. Restart. Drives fine. Shifts great. Stop. Shut truck off, restart, goes into limp mode . Repeat this over and over. When driving and it's not in limp mode, when you let off the throttle, it revs a little and unlocks torque converter, then when apply throttle it relocks torque converter. It used to only unlock when brake was applied. What is this issue now?? No codes even with scanner hooked up when it does this. What do I look for now? I'm so confused....

Starting a new thread on same issue won’t help. You already have forum member @NickTransmissions in your other thread helping. I’d try to keep it all there.
