Hey Mike I know this is mostly all dmax stuff but Im sure you would have knowledge on this as well.

My Brother has an 04 cummins that lost 2nd gear yesterday, so we pulled the pan and the first thing we noticed was a large selective snap ring looks like the kind that hold the clutch packs in place in pieces and check ball in the pan. We then pulled the VB and Im guessing its the 2nd gear band was broken. Any ideas what would cause all that failure? Its original trans and his Fiance drives the truck and tows mostly with it. The VB was modified to raise line pressure to 120-140psi.

We have been pricing kits for the rebuild mostly Goerend parts. What upgrades to the trans do you think will be needed to handle a bullydog programmer or possible a smarty in the future? Also does suncoast have kits for this trans?

Thanks

Goerend parts are good and I use them. Post a picture of the snap ring and ball. Front bands are known for breaking in the Dodge.

This is what we found. I think there is still more of the ring floating around.

Looks like the snap ring that holds the forward or direct clutches.

ive heard about 400 horse input shafts are needed in the 48's. suncoast does make kits for them, check them out. www.suncoastconverters.com

One more expense, but better now than more later. $700 bucks for the shaft sucks!!

Necessary evil. If the input shaft breaks it will destroy the converter and pump.
