I pulled my console to do a cdl upgrade, now the M&S lights keep flashing.
the truck is in limp mode as the gear indicator will only read D; no 3,2 or 1.

Normally I would think battery or alt. the battery is new (3 monthes) output is 13.5-13.7, low but it has alway been that way.

I never did get the cdl in before it got dark so i put the access panel with the old shifter back on and plugged everything back in (seats,windows, shifter soloniod) without the console. That was went i noticed the flashing lights.
The only real problem i had was removing the sport mode plug, do you think if I F'ed the switch it would put me in limp mode?

Or is it just my luck i save up for the cdl and now i have to by a Alt.

Oh Codes:
p0734 soleniod valve torque converter lock up
p0753 (soleniod valve 1 line short circut)
p0758 (soleniod valve 2 line short circut)

 

I'm thinking you pinched some wires during the reinstall before it got dark.

 

I agree, double check your work.

 

I will double check everything when I get home, like I said the console if off I just pluged everything back in hoping I could use it for work today. I'm wondering if i screwed up the sport mode switch disconnecting it would that put my truck in a limp mode?

 

yes. did you snap the latch on it? go back and see if you can take it off and put it back on. if not email paulgrant@mac.com and get a use one and splice it in.

 

yes; I did snap the latch as a matter of fact.

 

see that. i knew what you did without even looking. lol.. that latch actually pushes the connectors together. it's just not getting a signal now. i would get a used one from a pick and pull or off paul grant and splice it in. you should be good to go.

 

thank you i was not looking forward to spending $300 on an Alt. I kind of thought it had to do with that little pos. Did the same thing happen to you?

 

No it is not the sport mode switch, spliced a differnet one in no difference

 

the saga continues....

you connected both the transmission selector as well as the sport mode button right? one is a lot smaller than the other and could be overlooked in the dark. does the truck go into drive to actually get 3rd gear or is it locked in park?
