I have a 2005 fx4 with an auto transmission. I also have a 2006 manual with a 4.0,4x4 will the pcm work from the 2006 if I just swap them.

also I made a mistake and posted this in 19+ I’m new to this sorry

 

If both Rangers are 4.0l engines and both 4x4s then yes the transmissions can be swapped

But you will need to swap the instrument cluster and PCM as they are a matched pair on 2004-2011 Rangers, prevents odometer tampering
2006 also has PATS, 2005 didn't, but 2005 should still have the transceiver around the ignition key slot, if not you will need to swap that over as well, AND either way you need to swap ignition cylinders to use the 2006 PATS key with the 2006 PCM/Cluster

Since the Automatic harness will still be there you will need to jump 2 wires for START and splice 2 wires for reverse lights, on the DTR sensor connector

 

Do you think I could get away with just keeping the pcm and flashing it to avoid having to do all that stuff with the pats also should I take the harness out of the 2006 or just jump the wires like you said if I’m understanding properly thanks

 

You can use the 2005 PCM as is with manual trans, the CEL(check engine light) will come on and stay on but that's about it until its reflashed with manual software

Prior to 2001/2 all Rangers were wired as Manuals and the Auto harness was added to that
After 2001/2 Ford had 2 different full harnesses, Manual and Auto, and this includes some in cab wiring

Way easier to just jump the 2 wires than to swap harnesses, diagram below

At the DTR cut the pink and tan/red wires and twist them together, and seal the connection, you could run these two wires to the Clutch switch in the cab if you want

Also for Reverse lights, there will be a Purple/Orange wire(12v key on) and a Black/Pink wire OUT to reverse light bulbs
Need to splice those to the Reverse light switch wires on the manual trans, there is no "direction", the switch is either closed passes 12v to bulbs, or open, bulbs off
VT = violet, I prefer purple, lol

 

Ok sweet thank you for all your help I will try all that out sounds easy enough

 

Also excuse my ignorance but what is a DTR

 

Digital transmission range switch(sensor), on the drivers side of transmission on the shifter arm

Seen here: https://www.fordforums.com/attachmen...851-png.54506/
The black box, wire connector is at the rear

 

Ok perfect thank you sir

 

Good afternoon I have been working on my swap slowly lol. I was wondering if you could tell how the speedometer gets its speed I’m assuming it’s off the plug at the back of the transmission and how do I go about that tia

 

In 2001 and up all Rangers used the same OSS sensor for speed, upper rear of transmission, driver's side, manual or automatic, 2WD or 4WD
2 wire sensor

OSS wires go to the computer, the computer then sends out a speed signal to speedometer/odometer and Cruise Control(if so equipped)
In a 4WD when in 4low the computer re-calibrates Speed out signal for the ratio change

 

Ok so basically I just cut the plug off my doner truck and wire it to the harness on my truck to get it to work then?

 

Yes, and its a VR sensor so outputs AC volts, no + or - to worry about

 

Ok perfect thank you

 

OK so I have two problems, number one is my speedometer now is reading way too fast so much so that I can’t even get highway speed before the cut out. problem number two is now. My brakes are really hard and have minimal breaking.

 

Do you hear a hissing sound under the dash? It's possible you bumped the pushrod for the brake booster while you were installing the clutch pedal assembly. That can tear the diaphragm inside leading to loss of power assist.

 

Yeah I’m sure you are correct so that being said I’m assuming I need a to replace the booster

 

OSS sensor is not a VSS sensor, both are used for vehicle speed but not in the same way
OSS sensor connects directly to the engine computer, the computer changes the OSS 30,000ppm(pulse per mile) down to 8,000ppm(Ford standard) and sends that out to the speedo/odo and cruise

VSS outputs 8,000ppm so is connected directly to speedo/odo and cruise
(1998-2000 Ranger used rear axle ABS sensor, 20,000ppm, converted by GEM module to 8,000ppm)

Reads like you are getting the 30,000ppm at speedo
Could also be computer is being "told" you are in 4low, it then adjusts the 8,000ppm to reflect the lower ratio

 

I had a similar issue when I swapped my 2003 to manual, which is where my opinion comes from.

 

Ok so I have taking the booster off and you are correct I broke it so I have ordered a new one thanks for pointing me in the right direction

 

As for the speed thing what would you suggest I do to fix RonD thanks for the help

 

Did you swap computers?
And if so what year computer did you use in the 2005 automatic Ranger?

And what year was manual trans from?

Is the 4low light on the Dash on with key on?

 

No I didn’t swap the computer. I got some advice on here which worked well for jumping wires and I wired some plugs in for the reverse and speedometer. As for the 4wd low light it’s not on

 

The reason I didn’t swap computers is cause the manual trans is from a 06 and mine is a 05

 

I am thinking there is a difference in the tone rings inside the manual trans and the automatic trans

A Tone ring/reluctor wheel has teeth, looks like a gear
A VR(variable reluctance) sensor like an OSS sensor generates an AC voltage pulse each time a tooth passes by it
IF(big if) the manual trans and automatic trans have a different number of teeth on their tone ring............well different calibration would be done in the computer

But not sure
Unplug the OSS sensor's 2 wire connector, then go for a drive, no speedo of course, that's just to make sure the OSS was connected to computer, so not getting a signal from a different sensor
Automatic had the external ISS sensor as well and its a VR sensor same as OSS

The computer does have programmable options for axle ratios and tire size to calibrate it for correct speed, so software like Forscan could be used to recalibrate speed OUT to cluster

 

Ok I will try that thanks again for everything
