Same truck as yours. At about 160K a ring broke in the overdrive unit and cut a groove in the overdrive gear. Got it replaced but could never get all the fine metal out. It finally started collecting on the solenoids so I had the tranny rebuilt local. Lucky for me we have a company called Suncoast Transmissions here and they build a great product. Best thing I ever did. I picked up a couple miles per gallon because the thing was slipping so bad before the rebuild. Installed a triple disc converter, new valve body, billet input/output shafts, and other stuff. Raised the pressure so it really locks into gear now with minimum to no slipping. Dodge built some slip into the tranny because of complaints that it shifted too hard which eventually leads to wear of the parts.

I for one am not a fan of Sun coast. That was the T/C they used on my rebuild. It went out 25 miles west of Circle,MT. cutting the front pump up and seal leaking fluid all over every where. At this point I am 1400 miles from the shop that did rebuild so they sent parts out to Circle and I am on my way 4 days later. The local shop pulled my trans for a look see when I got home and also paid all of my extra expenses we incured like rental car, hotel etc. It does not have a Sun Coast in it now.
