Hey Guys,
I recently purchased a 1998 M1097. I knew the trans was in limp mode when I got it and the Trans Light will not illuminate.
I replaced the trans light. I replaced the Transmission Relay.
I checked the connections at the battery. I have power at the trans relay but when testing the pins at the J1 harness in the TCM I have no power.
I am assuming there could be more issues with limp mode but without being able to read the codes from the trans light (because it will not illuminate or flash codes when jumped) I am kind of stuck.
I did a visual inspection of the wiring harness under the vehicle. Nothing apparent.
I’m assuming it’s a bad ground? Possibly a bad 291D power wire?
I am looking for any suggestions on what to check and where to begin? I don’t want to rip out the entire wiring harness if it’s something simple, any thoughts?
Thanks in advance guys, this is a super informative thread.![IMG_9601.jpeg IMG_9601.jpeg](https://www.steelsoldiers.com/data/attachments/668/668559-ee0199f21db2802923ce7a9f2642ab03.jpg)
