2001 MT, factory-new boxed trans at 104k miles (original had ISB failure), now at 193k miles. Started popping out of 4th gear, but unlike the old trans ISB failure, this trans is completely quiet. No metal visible in the oil. Motor-mounts look okay. No problems with other gears. Pops out seemingly at random, maybe a bump in the road, or just happens. Popping out is not particularly an uphill or downhill event. I'm hoping a shifter linkage issue, but nothing is obvious visible, or in the feel of the shifting. Anybody else have experience with 4th-only popping out of gear?
