This 2.4L 4G69 5 speed Eclipse has a common failure of the input shaft bearing on the 1st gear end. This is also a common failure in Honda Civic transmissions as well. It's hard to say if these and the Honda units are defective, because any failure I've seen on these bearings if from drivers who are frequently accelerate in first gear at full throttle. This car had a decent sounding intake on it and it's obvious this is somebody's traffic light race car.
For the same reason that you accelerate the most rapidly (torque multiplication due to very high gear ratio) in first gear, that bearing on the input shaft gets the most force pushing against it. The output shaft bearing right that's also right next to 1st gear doesn't see nearly as much wear because during that pressure they both see in a 1st gear pull, the output shaft is turning with road speed (slow) and the input shaft is at engine RPM (winding up to 6,000). Same pressure but 4x the speed = way faster wear.
I apologize that this video isn't better, especially towards the end. I'm a flat rate tech using KZitem video editor and I have all kinds of interference while I'm recording and don't have time to redo things if things are happening that need to be cut out.
Comments are encouraged and questions will be answered.
