- 1992 Ford Explorer
I got this 1992 ford explorer two years ago from an uncle of mine who had no problems with the transmission. Im pretty sure he had said someone had done some work to it at some point as well....
During the first year that I had it, the transmission would shift up into what I believe is 5th gear which was great for highway because I would be pulling 2000 rpm going 65 mph. The gear would catch around 45 miles per hour as I was pulling onto the highway. As time went on it became harder to shift into this gear. The way I would get it to shift up there was to pump the gas so it almost "pulled it" into gear... a year later nothing works. I took it to my local mechanic who ran a few tests. I believe they put it on this treadmill like thing and speed the tires and transmission up to highway speed but couldn't detect a problem. But I know there is a problem because it used to shift and now it doesn't. So im stuck where ever I go in 4th gear running 2500 to 2700 rpm to go 65 to 70 mph which gets me 14 to 16 miles per gallon.
Can anyone help? I thought I read somewhere that I would need to replace a vacuum valve of some sort but I don't know. The wallet would much appreciate.
