Buddy has an 05 with no overdrive, randomly went out one night.... found a torn lip seal on the overdrive piston, replaced it, still no overdrive.... replaced the overdrive/tcc soelinoid. Still no overdrive... swapped with a good known valvebody. Still no overdrive... the ecm is commanding overdrive. The overdrive housing was cracked back by the tcase a year ago and he bought a used 47re overdrive housing and park rod... don’t believe that would cause an issue. Also put air pressure to the overdrive port when valvebody was out and it pushed the overdrive piston out like it should. Made sure to put the overdrive spacer in as well.
