Hello,
This is my first post. I have an 04 M1123 with a 6.5 NA engine and a 4L80E transmission. It was running great but is now stuck in limp mode and when I put it in reverse it stalls the engine. I am thinking it is a control issue with the computer. If anyone has dealt with this and has a solid solution please let me know. My truck does not have a transmission light so I cannot pull the codes yet. Light is ordered. I have access to another TCU. Any help would be appreciated.
