Hi everyone, I have a situation where my 2008 Silverado has been throwing code P2769 (Torque Converter Clutch Circuit Low) and it shifts hard which I plan to change the torque converter solenoid.

Over the past week, the truck has been acting up more where the electric cooling fans are constantly running. A couple of nights ago, I got the "Transmission Hot Idle Engine" light. I checked transmission fluid to make sure it is not low and it's actually reading above the full range. I changed the transmission fluid early last year. I have not added any transmission fluid since the fluid change. and the fluid level has been reading in the full range until now. Could the reading be off due to a failed transmission fluid pump?

Anyone have any ideas what my problem is or what I need to check? Thanks.
