Replace the TEHCM??

flip the pill inside your thermal bypass valve

replace the piston set snap rings in the 3-5-R and 4-5-6 drums? The 3-5-R apply/balance piston snap ring is more prone to failure and if it goes, it usually takes the 1-2-3-4/3-5-R circuit partitioning O-ring with it resulting in 3rd gear starts.

The 2012 and up 3-5-R drums will accept a spiral-lock snap ring in that location

Delete the AFM-active fuel management. Stops the engine from going from an eight cylinder to a four-cylinder.

Uh huh, sure. Exactly what I was going to say.
