Hey guys. So I just replaced the torque converter and did a fluid and filter change because the truck was bucking after 45mph and a shop diagnosed the converter. It fixed the issue but another one has come up. After it shifts into overdrive the RPMs will rev up 1-200 for about 5 or 6 times then won’t do it again for the rest of the trip. Sometimes the OD off light will blink sometimes it won’t. Al shifting is smooth as butter.

 

What is this on? Can't see your vehicle through the Internet.

If the OD off light is blinking, read out the OBD2 codes with a scanner that can read Ford transmission codes.

 

Sorry. It’s on a 2002 F150 5.4. I dropped it off at a trans shop to get a diagnosis and they told me there were no codes. Just told me I need a rebuild.
