I have a '92 Ford Explorer. Those things are notorious for transmission problems! I was having troubles with it switching gears, and it would act funny to a point where I was afraid to drive it. Trans Magic redid the entire transmission, and now my car runs very smoothly. I would've liked it to be done a little bit quicker, but I'm guessing those things can't be rushed. After a week of having my car back, I was having a few problems switching it into reverse, so I took it back, and he fixed the problem within minutes. Very good service, I would highly recommend.
