Uh o.

Got a P0700 and a U0404 in my ecm. Check eng light came on twice. I cleared them and the light came back on. I've been doing some research and you can clean the esm?

Also I'm getting a int. trans overheat light at startup. Also, all of my PRND are lit up as I'm in gear. That comes and goes, but today had a jerk into gear so I want to fix it asap.

Do I need just a ESM, or do I need more parts. Thanks!

Start with the esm for sure, the p0700 indicates there are dtcs in the tcm, likely unrelated to the u0404.

Re: Uh o.

The U0404 was in the TCM.
