- If it ain't broke, I can't fix it.
Let me start out by saying that I went down a long dark road during the journey leading up to this, so this one requires a lot of reading...
I have two 2003 Ranger Edge 3.0L trucks. One is at AT, one a MT. I wanted to swap the transmissions between the trucks, so needless to say I swapped all the necessary parts from the automatic trans truck to the original MT truck. I'm listing only the items that I think might affect this issue:
transmission
PCM
PCM/transmission harness
steering column
pedal assembly
To start the MT truck, I had to put a jumper on the clutch safety switch.
When I started the it, it ran fine for like 10 minutes and then started to run really rough. I think most of the issue was due to a vacuum leak at the PCV valve, but I revved the engine a bit to see if there was something obvious going on. This is when I first witnessed the engine cutting out at 3000 RPMs. It's almost like there's a governor set to cut the engine when it hits 3k.
I was already having misgivings about this swap, so this clinched it for me. I decided to swap everything back to the original AT truck. When I started it up, I immediately went to check on the cutting out issue by hitting the gas. Same exact problem I had when the AT parts were in the MT truck.
Anyone have any ideas? It obviously can't be an engine sensor problem as the sensors are different on the two trucks.
Here is a link to youtube with video of the issue:

Any help is greatly appreciated!
