Any ideas?

I recently (250 miles ago) installed a supercharger onto my rig. And, I also did the elocker mod that allows for the elocker to work in 2wd, 4hi and 4lo. Other than that, I have not changed anything. Two days ago, my 4runner stopped going into overdrive when it should (over 50mph etc...). Anyone have any clues as to why? Should I reset the ECU?

Thanks for any responses you have.

 

May sound silly...but does the dash say OD Off? Can we assume the OD button on the shifter is pushed in...?

 

Yea, it's in. I tried turning it off and on to no avail. I just noticed that the elocker is not locking so I am going to check the wiring and see if I messed something up while I'm there.

 

Well, I undid the mod and everything is fine now. I don't really know what the deal was, but I'd rather have the overdrive working than the elocker available all the time.

Has anyone else ever encountered this in a '99 4runner with the rear locker?
