>>>Crap! My gear shifter broke today, shifting from 3rd to 4th in normal, unspirited driving!!!! I was cruising along in 3rd and went for 4th gear at about 50 MPH and the shifter kept going and going. I was able to ease the thing home through California stops for about 10 miles, avoiding all stoplights, and get in my driveway. Rothrock sent a tow truck post haste and the car is on its way there now. It broke about 6 inches below the knob, but I did not have time to disassemble it for a better look. <<<
!!! Mine is going strong after 7300 miles. It would be helpful if we had some more detail here, some PICs and so forth. If the lever itself is still attached but nothing happens with front to back movement then it could be shift cable related for example. When I removed my console to paint it I noticed the upper ball-ended swaged on stud was wobbley, so I reswaged it tight. If it's loose it will cause slight play in the shift action and eventually fail from metal fatigue and wear where it rubs.
If it was the actual lever itself, something may be up with it. In such cases loading in another stock piece means the same problem may recur.
The kind of person I am...I'd want to examine it...and weld on another piece or something so that the problem is over with. Nothing like peace of mind.
