After installing new gears you need to pre-heat the gears just like new brake rotors. Here is how to do that:
- The first time you drive the car, only drive it about 15 minutes or so; DON'T accelerate hard or drive extremely fast.
- Stop the car and let the gears cool off for 2-3 hours, unless it's very cold outside then maybe a little less.
- Drive again for about 30 minutes or so; no hard acceleration or fast driving speeds as before, and let the gears cool off again.
- Then drive the car about 45 minutes or so, no hard acceleration or fast driving yet. Let the gears cool one more time.
