I just got my 94 ram 2500 cummins manual. Runs great. I have a violent shake or shudder when giving it throttle most of the time. Wondering what this could possibly be. Also my trans is different the pattern goes like this.
L2D
13R.
Is this the nv4500? Thanks guys glad to be part of the site

 

I'm not sure what that pattern signifies, but I'd check motor and tranny mounts.
