It started downshifting hard from 3 to 2 then it started doing the same from2 to 1st . The day it went out my trans temps went to 245 I pulled over and waited for it to cool down. A hour later at a stop light I lost 1 and 2 nd and Reverse. I called the dealer they told me 2 weeks to even look at it. So I took it to a trans shop had the option of a rebulit one or new one because they couldnt get parts so I choose the new one $5900. They had it in the truck and ready to go 5 days later. A Tech Transmission in Hesperia Ca big thanks to them.What a bummer! What happened to the transmission?
