    Default Code P0700 & U0404

    --------------------------------------------------------------------------------

    I Have a 2006 Commander 2wd 3.7 L. with the check engine light on. I took it to Advance Auto, they scanned it and got
    Code P0700 = Trans control malfunction.
    Code Uo404 = Invalid data recieved from control module gear shift.

    Anyone have this problem or know how I can fix this problem,Please let me know.
    The trans acts funny going about 30mph let off gas just coast then get on gas abit and let off and the trans acts and sounds like it shifts into low gear,when you let off gas the RPM's go up and you can feel the torque like it shifted into low gear.

    Now when in drive all the dash shifter lights are lit up P,R,N,D, and trans is still acting up. The other day it would not start,waited a bit and it started and got home,have not driven it since.

    I've been told I need a new shifter bezel / ESM part # 68004143-AF

    Does this sound like the answer to my problem? Will Installing a new ESM / Shifter Bezel correct the problem?

    I repleced the ESM/Shifter Bezel 2 days ago and all is good. Took about 30. min. Had Advance Auto turn off the check engine light. No more codes and check engine light has stayed off, trans shifts correctly and dash shift lights only light up the gear the shifter is in. The STEALERSHIP wanted $412.00 for the shifter bezel and $180.00 to install. I got the ESM/shifter bezel from a Mopar Dealer on E-Bay for $189.00 + 9.95 shipping,now that seller has raised the price to $319.95 + shipping. I got a hell of a deal.

    I'm having the same issues listed above with my 07 GC Laredo. I found this forum:

    I haven't done the contact cleaning yet on the ESM but it seems like it would fix the problem without having to replace it.
