i checked my PCM codes this morning to see what the check engine light was all about, i got 2 codes that make no sense at all.

code 45 - Transmission OD circuit failure

code 37 - Torque converter

What makes these odd? i have an nv3500 5 speed equipped truck..
What gives?

 

Those are perfectly normal for your manual transmission. After all, neither of those parts exist on your trans.........

On a more serious note... Has the PCM been changed? How long have you had the vehicle? How long as the light been on?

 

lol light has been on since i bought it last year, i knew it was running smooth so i never really worried about it, lol. no idea if it has a different pcm... dont think so because the upshift light on the dash still works and i assume that would be for a 5 speed pcm? The only other code was a circuit failure in EGR-- not too woried, lol

 

Shift lite may have its own driver, separate from the PCM, not sure on that. Best bet would be to get the part number off of your PCM, and have your friendly neighborhood Dodge dealer look it up for you.

I am going to guess that the PCM HAS been changed....... The one for the manual trans shouldn't have a clue about either of those. (and if it were out of a truck with an auto, both codes would make an odd sort of sense. )

 

i would have to agree with you, lol.
