1999 Dodge G Caravan. I am In Limp Mode with codes PO734,PO700.So I went to change the Output Speed Sensor and I found a lot of metal flakes stuck to the end of it but I don't have any flakes on the transmission dip stick. What now? Is there any thing I can do to fix this short of a rebuild.
Remove the pan and inspect. I would say you have a broken hard part. I have taken 4 transmission apart this week, and all 4 had broken planetary gear set. Which was causing no reverse or 2nd, 3rd and 4th gears.
