The truck was working perfectly up until I stopped by a local Subway. When I left the parking lot, I had the "O/D Off" light show on my dash when I never even touched the overdrive. When I turned onto the road I noticed my RPM's was going up to 2500 when I was going only 20 mph. I decided to go 30 mph to see if it would shift at a high RPM and it went up to 3500 RPM's. Clearly, something is wrong at this point. I continued to drive 20 mph all the way home (7 miles). As I turned down our neighborhood driveway, the "Transmission Temp" light appeared on my dash. The next morning, I drove it down to our family mechanic and it started shifting much better the fallowing day but the fact that it did the prior is my concern. I first was considering if it needed an oil change due to smell cooked oil after driving it. I bought this truck from a 3rd party several weeks ago and so I am unaware of when it was last serviced. Any suggestions?
