…They found chunks of metal in the transmission fluid and the following codes were displayed: P0767, P2535/P2703. No warning lights came on until the 10th to 1st downshift right before I made it to the dealership. This was a highly unsafe series of events that resulted in a destroyed transmission and a significant scare on my part while driving. Just blessed that no one rear ended me. The 10r80 transmissions have a TSB out on them but have no safety recall. This is not an anomaly. These same issues have been happening since 2019.

What should I do if my car shows P2535?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
