I have a 2000 Ram off road package. 360 with auto.Recently the truck wouldnt upshift into 3rd without stomping on the gas. So I replaced all 3 sensors in the tranny and it worked great for about a month. Now the exact same thing is happening again. Any ideas?????

 

I was ganna say that the cat might be bad, but if it worked for a month then started not working again im not to sure. I doubt that the sensors went bad again but maybe. Did you get any codes. By the way, welcome to DF[sm=welcomesign.gif]

 

no, I got no codes and I did the ignition turning and got nothing wrong.
