So after hauling home a new 5th wheel project today, I noticed that my new transmission gauge seemed inop. I tore down the dash and found the tap splice I used may have had an intermittent connection ( I hate those things) so I switched out a butt connector and that seemed to fix it. As I was there putting the dash back together, I figured I'd check the trouble codes for fun. It spit out the following:
P0622
P0743
P1693
P1765
Now I had noticed wayyy back in fall that the trans had shifted in and out of OD on the highway a few times on a few separate days but quit. I have since then installed a lockup switch on the dash. Would the lockup switch cause the codes because you are messing with the transmission signals- so to speak?
I did test the alternator with my MM and got .01- .02 VAC, not alarming. I also read the trouble code trouble shooter on the info pages, but I don't have a scan tool that can freeze frame and what not.
Could it be my 3 day old EZ causing this? I don't know how long these codes were present.
Any thoughts?
