Just got an 09 TC at work, spare van, and it’s starting to have transmission failures: No second gear, it shifts directly from first into third gear at around 5000 rpm. Manual shifting into second gear does not work either. Sometimes, it will shift out of third gear into neutral when I let off the gas. I have to put it into neutral, and then back into drive and give it gas to before it will catch and shift back into gear. Overdrive does not seem to work either. I have read on other forums where the throttle position sensor and other engine sensors feed into the transmission control system. We tried a quart of K&W Trans Medic, but no real changes. Any suggestions?
