Curt - I reduced torque on the TC motor until all selections worked fine. It took about 15 minutes of crawling underneath the truck and back in the cab. But yes, that was what worked for me.

That's great news. Please keep us posted on the Apple/Android aspect.

Any updates?

I don't have pics as I haven't installed the GJ cooler yet. However, I called their shop and they were helpful. You might give them a call and run it past them.

Keep us posted. I'd like to know how it is for the '12.

Daveypetey - I called GJ about the cooler (not the reservoir) and it will work with my Roush and the larger (Saudi) OEM trans cooler. Tim

That particular part you linked says it doesn’t work with a 12. I’m not sure why they are different. Dane - yes, 4wd and the iwe’s are working as normal.

I have 2h, 4h and 4l again. Once my boys got home from school, I had them operate the switch while I was underneath. I could hear the motor buzzing when the switch was in 4h. I took the motor off and it was operating back and forth as it should. I moved the transfer case selector shaft and...

Dane - I went out and took the vacuum lines off the IWE's. As before, I could not turn the front driveshaft. I moved the switch to 4hi and it still would not engage the transfer case. I tried driving back and forth in the driveway but no dice.

Sernas - in addition to what I wrote above, is this a common problem? I guess I can plop down the money and get an OEM motorcraft one but am hesitant to just throw another part at it. However, i did read other reviews of Dorman's shift motors and they aren't good. Thanks, Tim

Dane - I went out and checked the front driveshaft with the truck off. I cannot turn it. I turned the truck on and checked it again. I can turn it. I shifted to 4hi and can still turn the front driveshaft. That was the "failed 4x4" as you referred to it. Sernas - I got it from Dorman via...

2012 Roush Raptor SCREW. Will not shift into 4x4 hi or lo No grinding, no popping from IWEs or Transfer Case Checked vacuum at IWE solenoid and even bypassed solenoid to confirm IWEs are working Received a check 4x4 when trying to shift to 4hi or lo. This week I replaced the transfer case...

Can anyone confirm if the GJ PS cooler works with the larger OEM trans cooler (DL3Z-7A095-B, standard on Saudi Raptors)? I can't tell if the two will interfere but it looks like NE Ford might be running the same cooler.

jhollowell - I have the same issue too. Not sure if there's a fix but I'd like to know too.

spatel - thanks for the updated info. This is good info for those of us with 2012 and older. Please keep us updated with how you like the system and whether you run into any issues.

I replaced mine with OEM Motorcraft via RockAuto. Seemed to have a pretty good price.
