8-Speed Shift Points

Not happening.

Traction control.

I beg to differ. Traction control is reactive, software is designed to be proactive...

I DO know that Dodge had issues when turning right and punching gas that they would snap the power steering pump shaft... I KNOW from experience and research..... maybe that's part of what they're after in correction....*shrugs*

P/S pump? Aren't the 4th gens all electric p/steering? I know my '14 is.

Only 13 or 14 and up have electric steering. I forget if it came with the front end and interior refresh or the 8spd.

That's an interesting theory with the right turn throttle...

The electric power steering, ZF 8spd and mid-generation update (facelift) all came with the '13 model year.

The ZF was an option in 13, no?

It was on the 3.6L V6 in '13, it was an option on the Hemi in '14

It was a MY 13 option on the higher trim level 5.7 trucks,and the very rare 2013 HFE trucks with the 5.7 came with the 8 speed. All the literature on the 13 HFE trucks shows them as a 3.6 truck,but Ma Mopar made a few of the early HFE's with a 5.7 / 8 speed, i looked at one on a dealers lot in the spring of 13,and there was a guy over on the other Ramforum that had one,they are very rare,but they did build a few 5.7/8 speed HFE's in 2013.

2014 1500 4WD - I'm sure other 5.7 8HP70 (8-speed) owners have noticed this as well; the transmission delays the 1-2 or 2-3 shift points slightly when the steering wheel is off center. For example, when making a left through an intersection after a full stop, or a right from a stop sign. I know it's not a problem, but I'm curious why this delay would be programmed into the PCM. What were the Engineers trying to achieve? I would have thought an earlier shift would have kept the torque down if they were trying to reduce the chance of wheel slippage while accelerating through a corner. Typical me just trying to analyze the Engineer's logic...

Thoughts?

I had a 2013 Laramie with the ZF 8-speed and never noticed what Green Diesel Engineering calls as "shift schedule offset based on steering wheel angle". This is one of the annoyances that GDE removes in its transmission tuning, at least in my 2022.

When I took delivery of my 2022, I really noticed the shift schedule offset based on steering wheel angle. It was very noticeable. In my 2013, I never noticed this and I don't know if it was even present on the 2013. The reason for it is, well, it doesn't make sense. My best guess is they are either trying to save the front tires or it is a method to help improve fuel economy.
