So I have a 06 ram 1500 with the 5.7 hemi that is stuck in limp mode and I pulled codes and it say LR circuit failure so I took it to a shop and they say it’s a wiring issue so I went and unplugged the wire from the trans and the computer then I reset the code and it drove just fine for about 20-30 min and then threw the code so then I cleared it again with out unplugging the wire and I got only like 5 min until it threw the code again so anyone have any ideas where the wiring issue is or what it can be thanks

 

What was the code?

Shift Solenoid A Malfunction

Don't know if that one is replaceable on its own, or, if you need to replace the entire solenoid pack.
