Hi I was wondering if anyone would be able to help me out by telling me ways to test a 48re transmission without actually being able to road test the vehicle. I'm looking at a 2003 Ram 2500 with 240,000km on it. It's in a auction lot so there is no way to actually test the truck, but I do have access to the keys and am able to start the truck and put it in and out of gear, as well as rev the engine. Today when I was looking at it, I put the truck in gear, and at idle the truck engaged nicely, and lurched forward a little bit. I then held the break down and it would rev to around 2000rpm before moving. I know that this is all relative to the tires and how good my breaks are, but what kind of tests could I do to test the transmission without actually being able to drive the truck? It's looking like I'm going to be able to get a really good deal on the truck, I just don't want to have to rebuild the tranny right away. I had a local dealer check the vin number to insure that it is a 48 tranny. Any help is greatly appreciated.
