P0700 Code Transmission Control System ( MIL Request )
2018 Chevy Silverado 1500 is showing this code. It is in limp mode right now and won't go past 30 mph. From your experience what is the most common problem and cause to encounter this problem? I change the transmission fluid on time so I'm hoping the transmission is not bad. Currently at 100k miles. Anything helps.
Details on that code here with some troubleshooting information:

If it's not a visible problem like bad connector or low fluid, you'll probably need a professional-grade scan tool to analyze the transmission.

"The P0700 code is informational. The code points to a general fault, not a direct fault. To correctly identify the problem, you will need to have a scan tool that communicates with the TCM to determine the problem in the transmission."
Ok thank you. We took it to the dealer and also went to a transmission specialist shop to get a second opinion and they both said there is internal problem with the transmission. Is it better to get the transmission replaced by a remanufactured or to fix the transmission?
Is it better to replace the tranny or fix it? For both the price range is $6,000.
$6k just to repair a transmission seems kinda high to me.
If the costs really are that close then there's no doubt you should choose to replace with a warrantied and remanufactured transmission.

Get a factory-remanufactured transmission with a good warranty.

I'm not sure I would keep a late model 1/2 ton Silverado much past 100k to tell the truth.
