06 just started shifting crazy
my 06 is shifting hard then shift smooth like it doesn't know what gear to shift into. shifts just don't seem smooth anymore. feels like a shift kit was installed. does the same with a/c on or off load or no load. i did the trans relearn when battery was disconnected at 1000 miles. the truck is stock with 10,000 miles. anybody ever have this problem?

Coking (carbon) Deposits in Turbo and/or EGR Valave:
Exhaust Smoke/Smell, Harsh Transmission Shifts, 2005/06:
2005/06 F-SuperDuty and Econolines built before 12-5-05, and 05 Excursions built before 1-10-05, may exhibit excessive exhaust smoke with complaints of increased odors while operating in high idle (PTO, charge protection or cold idle mode), as well as harsh tow/haul 3-2 downshifts while slowing down grade under load, or tow/haul 5-2 downshifts, shift hunting in normal or tow/haul mode, or late 5-6 shift in tow/haul. The computer should be reprogrammed with calibrations included in release B39.15 or higher, or B40.2 or higher.
