I have a 2002 ram 1500.. Truck starts and shifts into gear just fine.. I get to right before shifting into second gear and the best way I can describe it is like someone slamming on the breaks while I'm driving. I have no noise coming from anywhere except The screech of the truck when it locks up. We have removed the rear axle and checked the pumpkin ball (everything looks great). We're in the process of checking out the solenoids. Anyone have any other ideas of what this may be? Thanks in advance!

 

Trans trying to hit two gears at once.
