Another reason to buy Goerend after installing the tranny i thought i had flushed the cooler good enough it was the original cooler from 1996.because of my oversight in this matter transmission problems came sooner than later.In short it was my fault period.But because they are who they are it was repaired no questions asked and no charge.You just cant beat good people,Thanks Dave& Craig.To the rest of you do it yourselfers save time and trouble have your cooler completely flushed and clean doesnt matter how new your tuck is.
