Transmission shifting hard on 2006 Dodge Ram 2500

Have you had problems with your transmission shifting hard from 1st to 2nd with high RPM's? If so, what did you do to fix it? Will Lucas Transmission additive fix it or make it worse?

I wouldn't go adding anything to try and resolve this. There are a couple of technical service bulletins from Dodge that are possibly related, I would take it to the dealer, have them check it out, have them check to see if it has the latest software in the transmission module, and check to see if these bulletins apply:
TSB # 21-015-05
TSB # 21-009-07
When you take it in, try to take a technician for a test drive and demonstrate the condition to the tech. This will increase the chances of getting it resolved.
Good Luck,
