2009 journey SXT 3.5 89,000 miles Transmission is making a high pitch whining noise and rpm's go to red line and won't shift until letting off the gas. If you turn the car off it goes away for a little while, shifts fine and then starts acting up again. There are DTC codes present. They are...P0735 Gear 5 incorrect ratio, P0729, P0733 Gear 3 incorrect ratio, P0734 Gear 4 incorrect ratio. Tranny fluid level is good. Any ideas what this could be? Thanks
