Model Years Affected: 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997

Average Mileage: 159,925 mi (125,000 mi - 225,200 mi)


At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

    On a cold start, the car won't shift into high gears until it has warmed up. My driving is all highway and I'll be cruising at 65 mph in 3rd gear. I can barely hear myself think until it suddenly decides that it should sift.
    I haven't had it fixed as I've already ordered a new car and don't want to be putting money into this.

    Doesn't want to shift when cold. Used to be just over drive, now it's all gears.
    Stays in 1st gear for half a block. Takes 2-3 miles to shift into overdrive.

    transmission is an automatic. on the highway, it runs along at 60 MPH in 3rd gear at 3000 rpm, and when I start up a hill, it shifts into fourth, as soon as I head back down the hill, it drops back into third. As this problems persists, my mileage has dropped about 15%, from 38 on the highway down to about 31.
