Weird DTC's

[rbr]

Has anyone ever had automatic trans codes trip on a 5 speed? I have had a 24, trans output speed low. A 44, EGR pulse width and 45 EGR vent output failed. The truck is a K3500 w/o any EGR equipment and a 5 speed. I thought it was a ECM going South but a new one did the same thing. Ive been over the grounds and just re did all the battery cables with no change. It is running like poop too.

Did you replace the ECM with one that was like the one that came off or did you get one that was for the VIN on the truck.
To my knowledge an ECM for a 3500 with a stick shift cant trip out codes for an automatic with egr..

How long have you had the truck??

Let us know

I have had the truck for about 4 years and it was the ECM that was in it that started the weird codes. The second one is a VIN number AC Delco replacement. I'm going to try a second scan tool to see if mine is part of the problem. Thanks for the note!
