I have a 2005 Tundra Double Cab Limited with the 4.7 vvti and the 5 speed auto Trans.
The Transmission won't shift into overdrive on its own, so what I have to do is to push the "Overdrive" button to off, and then
push it again to turn it back on and then it will shift into overdrive...
I have to do this every single time, but the Trans will shift into all the other gears just fine.
I Took apart the stearing column and found the wire from the shift lever had been rubbing, I taped it up in hopes that it would cure
this issue but it didn't. I just got a new shift lever today and installed that thinking there could be a possible short in the button itself
and the new lever didn't fix the problem...
Any Help would be greatly appreciated. It is killing my mileage and is more of a pain in the butt to push the button to drop my RPM's
(I have searched for solenoids or wiring into the trans that just for the overdrive and I can't find anything out)
Thank you for the help in advance
