I have a 2009 Silverado truck and I put a 2010 Yukon Denali 6l80e trans in it. The truck previously had a 6l80e trans in it before and it went out. found a 2010 Yukon Denali 6l80e trans and it appeared to be a fit and that it would work. I've had it installed for 6 months and it shifts fine and never had any problems. But from day 1 of putting the 2010 trans in, the check engine light came on and has not gone off. I hooked my snap on scanner to it and it read a code of p0700 'TCM requested MIL illumination (symptom 00)- current DTC. Test failed since DTC Clear, history DTC, test not passed since power up, curent DTC since power up' on the engine side and a code of p2535 'ignition 1 high voltage' on the trans side. I did an hp custom tune on it and was able to delete the p0700 code from the engine side, but it will not let me delete the p2535 code from the trans side. I replaced the ignition switch and did troubleshooting on all other aspect's of the ignition switch and relays and it still did not turn the check engine light off or remove the code.
It also shows the p2535 code is 'undocumented' on the scanner. GM's transmission code manual does not even have the p2535 code listed as a code that a scanner could pick up for a problem.
Anyone have any idea how to remove this p2535 code and get the check engine light off? Everything has been tested and everything is running proper voltage in the ignition switch and entire ignition area. Battery is running proper voltage. No wires are corroded in the the ignition switch or on the battery. All relays and fuses are good. Replaced ignition switch just to see if it would work and clear the code and turn the check engine light off, but it didn't work.
