I have ZF 8HP70's in all three of our daily drivers, but all programmed to behave very differently. All great transmissions, but I really like the way they set it up in the SRT 392, with shifts so crisp it chirps the tires up thru 4th gear under any moderately-hard accelleration. You feel every shift, especially when set to Track Mode, and it really winds the gears out going up and downshifts agressively on the way back down.The 8 speed transmission in my Jeep is the sweetest I’ve ever owned. It’s always in the right gear, and the shift points are not noticeable.
The 8HP70 in my wife's Durango R/T is normally set for smooth shifting, but switching to "Sport mode" makes it behave a bit more crisply. The one in the Ram 1500 is similar, but in that case it's "Tow Mode" that makes it behave more like a sport mode.
What's really cool about all of them is that the behavior is totally programmable, so those who want to run a tuner can probably easily adjust the behavior.
It's always tough for one to understand why everyone doesn't think the same.Yeah, I think so.
If I'm not mistaken, you've posted elsewhere that you're into muscle cars, maybe that goes with the territory. I'd guess most of us appreciate smooth shifts though.
7 liters displacement thru a 2800 rpm lock-up converter and a rear gear ratio so high you can hear it whine? Sounds like a nice daily driver, for running the kids back and forth to daycare.
