I recently went to the local trans shop and had the replace the fluid and filter in my 99 ram. The trans was rebuilt about 5k ago and it started shifting like garbage but no real slipping. They took the pan off and holy cow there were metal shavings everywhere. While there are acceptable amounts of shavings I feel it was beyond excesive. Now the shop says it needs to be rebuilt again. The truck sat for over a year after about 1k miles on the trans. What would you consider to be to many shavings?
