Is 68RFE limiting tow capacity?
I have been expecting Dodge to increase the tow rating on the new powertrain. In the old brochure they spec the 5.9/manual/3.73 at 15,400, but the 5.9/4sp/3.73 at 13,500. So with all of the lower gears on the 68RFE, I expected it to jump in line with the 4.10.
Well I just got a new brochure, and it says 6.7/6 spd/3.73 at 13,400, a loss of 100! But the 4.10 will get it back up to 15,400. Dodge is the only maker with a 3.73 towing so little. Surely the 6.7 can't be the problem. So does this mean that the 68RFE is a lot weaker than they have been marketing?
The 68RFE has lower gears in 1st, 2nd and 5th than the Allison. And on a GMC/Chevy there is no penalty for 3.73 like this.
I was getting ready to order a truck. Now I don't know. I really do not want to order 4.10 gears.
