Here's the problem: 1990 Bonne SE, Has good reverse, but no forward gears at all. The shifter arm on the tranny is moving properly when moving the shift lever thru the gears. For the last few days, when shifting into drive on a cold/cool engine, there has sometimes been a buzzing or whining noise for a second or two, but the noise would quit and car would operate as normal. Today, wife went shopping, 3 or 4 mile round trip. All was fine 'till she stopped for a traffic light 1/4 mile from home (on the return trip). When she accelerated from light, the noise occurred, then about 100 yards from home all forward gears stopped working, no noise at all. Fluid is full, does not smell burnt.
Any suggestions on what I might check before going to a tranny $$$hop? Appreciate any help,.... Jim
