Biggest complaint I hear about the 68 is the shifting. Have no idea what that actually means. Mine seems to shift fine. I get a little bit of a harsh downshift while towing in cruise control on a steep grade, and that seems to starting to smooth up. Other then that no complaints
My 2007 with 68RFE often downshifts VERY harsh if I have EB or T/H on. 3-2 downshift at low speeds slams gears beyond anything reasonable. Huge jolt. Once I exit highway I have to turn them both off. Dodge has a TSB to address this exact issue. Had that done back in 2007 but didn't solve the issue and Dodge would not do anything further. I've gotten used to it, just don't use E/B or T/H except on highways which is where they are needed the most. Otherwise its smooth. 92K miles and no trouble.
