Today my 1990 240/auto shift lever started making funny noises. The first thing I noticed was that when depressing the release button and selecting a gear, the shifter rattles across the shift positions. Sounds like poker chips clanking. At 65 mph there starts to be a rattle, again sounding much like poker chips being shaken. If I pull back or push forward gently on any part of the shift lever, the rattling stops. There is also a loose feeling to the lever. The lever- thus far- continues to select gears correctly. The OD button on the shift knob works properly. It kicks down correctly when passing.
Any idea what's wrong? Loose linkage? Something broken? Thanks!
