was breaking in my new engine today and on the 5th tank when i was driving it is now trying to shift as the engine is breaking in. problem is when it shifts it don't always grab it free spin then when the rpms come down it will grab does this alot. do you think it is the oneway bearing on the black nylon gear that slips.took it apart there was a little oil on the shaft. or its just bad bearing but it is a new tranny. and does anyone know wear the pre set shift points are for 1st to second and 2nd to 3rd? i did play with it when i had it a part. i might just put the 2 speed in to finish break in then worry about the 3 speed. just wondering if anyone else has had this issue?
