Hi,

There were two different controllers that were used. One is an NGC (next-generation controller) and the other is a GPEC (global power engine controller). Do you know which one you have?

If I recall, the GPEC was used with a CVT transmission. Is that what you have?

Let me know.

Hi,

Interestingly, I'm showing a different OEM part number for the ECM. See pic 1 below. Was that number on the original component?

Let me know.

Hi,

If the ECM and programming were done by a dealer, I suspect it was done correctly. So, we need to check for different possibilities.

Explain to me exactly what the transmission does.

Sorry for so many posts. These are difficult when the vehicle is in front of me.

Hi, I got the ECM on eBay used with same part number and year, and switch the VIN, everything work okay, except the p0765,bat no wary i return that ECM back for refund, and send mine original ECM for repairs, that's what transmission technician sees there is problem with TCM.
