Shift 1 through 6 like it is supposed to but overdrive did not work

The transmission started acting up shifting into fifth and sixth. It acted like it went into limp mode. So I checked transmission fluid. When I did I noticed that the dip stick tube was broke into where it bolts onto housing. If I put transmission into fourth gear manually it shifted just fine. But overdrive did not work. Then it started acting up when it shifted into fourth. Now it only works if you shift it into third manually. If it shifts into fourth, the RPM's go up like it is slipping and you cannot get it to shift out of fourth. The only way to get it to work again is to stop put truck into park and turn ignition of and restart truck.

It sounds like the transmission is going out or the PCM, but we should do a pin to pin test using the wiring diagrams from earlier and follow this guide to confirm.

If you want to try the PCM here is the location you can get a programmed unit from eBay.

Please run down this guide and report back.

Cheers, Ken

Okay then let's service the throttle body start by disconnecting the battery and when you are done clear the codes.

Remove it to clean it thoroughly then clear the codes and retry.

That is for the engine coolant sensor which can cause all kinds of issues. Let's check the connection at the sensor if all looks okay replace the sensor. Here is a guide to walk you through the steps and the location of the sensor for your truck below:

Clear the codes when completed. Check out the diagrams (below). Please let us know what happens.
