2013 PTU replacement

I recently had my power transfer unit replaced on my 2013 CX-9 with 102,000 miles (Serviced the fluid @ 50,000 and 90,000 ). The symptom was transmission shutter (No leaks). Total cost was $1540.00 at my local independent garage.

I was shocked to see corrosion and heavy wear on the splines and pitting on the bearings. I consider myself lucky.

looking at the splines, i am afraid your transmission splines will be shot too, your new transfer case will probably not be usefull for long

Wow, yeah just took a close look and they are really chewed up. Comparing the clean splines where at the bottom of that input shaft shows a huge difference with the part that engages the transmission. Not knowing what the transmission shaft looked like it sure does make this repair a little suspect.

I hope it will work out well for the OP though and that the transmission shaft is in better shape than the PTU shaft.
 
Usually it is the transmission splines that give first as they rust and get destroyed into little rust powder, the chewed splines in the TC is the result of the pieces of metal in the transmission's output that runs around in there. The TC slips and then it is pretty much over.
