The vehicle in question is a 1988 Accord Lxi, cable-operated 5-speed, 4 cylinder. I asked a repair shop to replace my clutch. Upon completion, I drove with my Wife to p/u my car. It seemed difficult to shift into first gear while running, but I managed to drive the car home. Shifting from a stop into first became progressively more challenging, culminating in my adding nylon washers to effectively lengthening the clutch cable. That helped for a few months, but the issue recurred. After researching this, I speculate that either the synchromesh has failed, or the shift fork is bent (possibly bending more while I shift). When I lift the vehicle and place onto stands, the transmission will easily shift into all but reverse while engine is running w/ the wheels turning while in each respective gear. It will absolutely not shift into any gear with engine running, wheels on the ground, regardless of clutch position.
