Under light load and when you coast it makes noise. Have any of you had this problem, if so what did you do to fix it

The Getrag's use a bearing race machined into the rear of the input shaft, rather than a standard bearing cup. When it wears, you have to replace the input shaft along with new bearings. I don't know the current price, but the input shaft is fairly expensive. It will probably run quite a while as is, but if it bugs you it's probably cheaper to find another trans.
