Has anybody had a 47RH behind a 5.9 Cummins rebuilt? If so who did you use to rebuild it and what upgrades did you make. Yes, I've been reading several Cummins/Dodge forums but I'm hoping to hear what the locals have to say.
Well, my motor is basically stock. The trans was rebuilt about 16,000 miles ago with some upgrades. So, imagine my delight when it slipped while towing around 10-11k pounds up a little hill. Unfortunately, I aquired the truck after the trans rebuild was done. I've also found out the the shop that did the rebuild might not have been doing the best work possible.
I've got to drain the fluid and see what's down in the pan. So, I might be jumping the gun here.
drain fluid, then adjust your clutch bands and replace with synthetic tranny fluid
hopefully that will take care of your problems.... instructions http://www.google.com/url?sa=t&sour...sg=AFQjCNE5fCryALRo8RntHmBMzGuN0n7ZNQ&cad=rja
there's several other things to do if you are a competent mechanic with tools. loads of help on the Cummins forums.
you need a factory workshop manual if you go very deep.
otherwise $$$ for a pro to take care of.
I've got a factory service manual for the truck. Running some pressure tests on the transmission is defintely on my to do list. I'm going to check out my TPS while I'm at it just for good measure.
I'm hoping the synthetic fluid and extra capacity that are in the transmission did their job.
