The best info I have found for the 8L90 without a doubt. Thank you.

Where can I find a replacement "Default Control" solenoid? I managed to break the little plastic connector plug when doing a fluid change. Having a difficult time sourcing the part online.

Awesome info, please where is the air vent located for this transmission?

On a 2017 Silverado with a 6.2 what information can you tell me regarding a thermostatically controlled transmission cooler bypass. Is there a way to get the fluid to flow to the cooler all the time?

Great video! Can you or anyone tell me if when swapping the solenoid harness which contains the temp sensor, do I need to do the relearning process? From the video it seems the answer would be no, just swap the harness, fill the fluid and, and be done. It appears the valve body and other components are not necessary to remove, just the fluid, pan, and harness itself. Thank you

Order internal harness with temp sensor , no relearn.
