New transmission

I can't tell you about the metal shavings, but I have had several MOPARS (Chrysler, Dodge, Plymouth) that I drove long enough to have transmission problems (typical for me anyway to have them by 130,000 miles, sometimes as early as 90K (or a hair earlier), and sometimes later than 130,000. Mine were minivans and sedans, not full size vans. But anyway, the cheapest deal I had for a rebuild was $1,200 a good number of years ago which was an afterhours repair will only a handshake warranty. Even that would cost much more today, if you could even find someone to do it. You will want a written warranty. I have paid in the ballpark of $2000 for a full rebuild several years ago for a minivan, and would expect that to be higher now. My last transmission diagnosis on a MOPAR minivan was now 7 years ago and the estimate was $3000. What I am getting at is that a $2,200 estimate if it is a complete rebuild seems like a very fair price today. Get the warranty, and before you commit, ask what warranty network they belong to. I believe many repair shops, whether a chain or not, may have a way to offer nationwide coverage of the warranty, but ask to make sure.
