46RH rebuild?

Not familiar with that shift kit as I usually just use their TF-ODjr.
I agree with getting rid of the plastic accumulator
I'm dead in the middle of rebuilding a newer version of your trans, the RE version. It has over 300k on it, was last gone thru around 60k ago. And just a basic rebuild then. I'm adding some HD parts this time like the superior and sonnax band strut, and billet servos plus sonnax HD spring for the OD too.
I put that ODjr kit in this trans when it was gone thru... Which was done only because I put a lower mileage engine in it and didn't know the history of that particular trans before I owned my Durango. It went out over the summer, and I stuck a junkyard one in that got me a whole 3 months. I ain't changing a trans that often (hell have you priced ATF+4 lately?) So I ain't chancing it with another one from the junkyard as I can rebuild this one for less than one costs these days from the yard.
