P2723/ p0700

[Larry245]

I was on my way to Nc this weekend with the Family we stop in Maryland coming from New York my truck wouldn’t go into gear then it went into limp mode. I scanned it and got P 2723 and P0700. I had to get it towed from Maryland to New York. Luckily I had AAA does this mean I need a new transmission, selonoid or valve body You can also hear the torque converter while the engine is running

Fluid level good and not smelling burnt? How old is the fluid?

If you do not have a bi-directional scan tool for diagnosis, take it to the dealership. The dealer will tell you exactly what's wrong, it might need major repairs or it might need a new TECHM. You can rebuild the TECHM on your kitchen table.

If you take it to an independent shop they will tell you it's "toast", "fried", "broken", etc. and sell you an entire unit when you may not need it. At the GM dealer's transmission will have a 3 year 100K mile warranty that can be serviced nationwide.

This sounds like a TEHCM issue, specifically clutch pressure control sol #5, stuck off. It can also be a cracked 1-2-3-4 piston which would produce the same symptoms (no forward movement in Drive or Manual).

Where is the vehicle now?

The whole transmission or the fluid? Either way, put her on the severe service schedule.
