2015 3500 Aisin . Low line pressure. Limp mode. Has happened before when changing trans fluid and it happened again after driving in rain, but it cleared. Got it again this morning onstart up. Won’t clear. I’ve got a manual and wiring info on order but it won’t be here til Monday. Anybody know of any connectors that may be involved? I have to think it’s a wiring issue due to the wet/ damp ange.

Pull the connector apart that runs along the frame under your feet going to the transmission. It is behind the inner fender. Check each wire for push out.

That’s where I’ve been and I found a light blue ( I think ) wire on the trans side of the harness that appears to be chafed. It’s so close to the plug I’ll have to solder it. Im looking for a magnifying glass to confirm my suspicions. I hope I’m right.

It appears as though that was the problem. PIN number 1 in the trans side of the harness. 1/4 inch long nick in the sheath caused a 1 inch long disintegration of the wire. I soldered in a splice. It wasn’t easy as the nick in the sheath was only about an inch from the plug. Thanks for the help. It made me feel better about tearing things apart.
