I think that is a very fair price. If they did a good job, it will last a long time unless you have the truck turned up for power.

Everything on there looks normal except for the input shaft. Was something damaged on the old one? That shouldn't normally be replaced when doing a rebuild. Did they say what the stall is on the torque converter. Looks like they put in upgraded or HD parts, you should be good to go now.

They reported that the input shaft was cracked. I didn't personally verify that. I don't know the stall on the torque converter, sorry. The HD parts was part of the reason I liked this shop right off. The original mechanic just wanted to drop in a one-for-one replacement. This shop was right off the bat with, "Yeah. That transmission sucks. Here is how we will make it not suck anymore."

I have heard of lots of people upgrading to billet input shafts because of other modifications. Really no need for a billet input unless you are planning on boosted launches.

When Dodge put the 48RE in the 2003 trucks they didn't build them as strong as they could, only strong enough to hold stock Cummins power. And they put a cooler on that was good enough to keep them from burning up during heavy use with the converter unlocked.

The truck cannot come to a stop with a locked TC without killing the engine if it's in gear.

The TC is barely strong enough and is a good item to upgrade if the tranny is out of the truck. Other items are the input shaft and the intermediate band. A valve body upgrade will make firmer shifts which means less slipping and wear. Many heavy duty parts are available that can make this tranny hold enormous power.

There was also some weak flex plates installed but I can't remember the year. It might have been 2004. They can crack, so a close look is good, or replacement.

I've got 270,000 on mine now and have to be a bit careful. At 100,000 I upgraded the TC, but cheaped out and did not get a triple disk. Big mistake! My Cummins is turned up and I can slip the converter anytime I get on it too much at low RPM.

When it comes time I'll probably get Georand or other quality heavy duty trans, but not one from Chrysler, as it will be the same thing I started out with.

It would be so nice to slip an Aisin 6 speed auto in, but the earlier computers can't operate them.
