this trans has 75 pases on it and worked flawless last season,tried a couple converters in this unit this year and went back to the converter that was used last year,and lost second gear,like i said we tore this down and it looked perfect ,clutches not even burned,the steels have no signs of chatter or burning (if it was a presure issue you would think it burn clutches)upon inspection of the sprag it worked as it should but there where a few small marks on the outer race but considered normal,
but if the sprag rolled wouldnt second gear not operate at all? or will it roll back and opreate normal until the load was recreated ??? gmonde
