2-3 modulator code on a 2000 f150 5.4 auto-overdrive 4 speed w/ 14 bolt pan. Most times it revs up the rpm's before it shifts into 3rd. Sometimes shifts hard only into 3rd gear. Sometimes it sneezes when it shifts into 3rd. Once in the gear, it runs fine. I am told by one mechanic, that it is not an electrical problem, it needs overhauling. 160,000. Overdrive light flashes[more when it is warmed up. Sometimes it shifts normal. Seems to be getting worse. Please help.
have the same problem?
