Not trying to pump your tires, but I really like your posts.
Yep, he has good info and a rational logical view.
who cares, just reference the damn thing correctly. Thats all i am asking, there are a lot of folks out there that less then basic knowledge about how things work.
It’s just easier to call it a ZF transmission. It’s ZF design and all of that that came with them monitoring the manufacturing practice. I mean, on BMW forums do the owners argue over the ZF transmission on an X3 vs an X3 M having a different internal name? ThaT might be a bad example because BMW owners, but shit. Life’s too short. If the diesel transmission was built in the US would you care so much? I don’t think so. I think you’re caught up in the fact that it’s manufactured by ZF. I used to work for a BMW dealership. The ZF built transmissions fail also. It was the same when I worked at an Audi dealership. It’s rare for any of them to fail, but it does happen.
MY 2021 JTOD has the 8hp75 transmission. My only complaint with this is not the trans itself, but the programming. In 2 wheel mode the shift points are too low in rpm in my opinion. It will shift at about 1500 rpm and get into 5 gear at 30kph. Too low for any type of throttle response for a gradient. The engine is stuck lugging - not a good condition for this engine.
That's been my complaint about the gasser transmission. It shifts too quickly keeping RPM low. You really have to give it throttle to keep the RPM up and delay shifting. On a hill even it wants to upshift and then finds it can keep up and downshifts again.
Yes, and I found that using 4x4 mode around town makes it really a lot nicer drive. The fact that the streets have been covered in snow for a month now due to the cold has made me ponder how to jump out the sensor, or trick the position switch if there is such an animal, so that the trans thinks it is always in 4x4.
Weird year here - very little snow, even the last snow didn't give us much and it was off the roads pretty quickly.
Yes, the first time I used it I wondered about it. Then I figured out that the system I had spec’d out when I ordered does not have the auto 4x4 engagement, it is a fully manual transfer case. So possibly that makes difference, but since I have not driven a model with the auto system I don’t know if my perception is valid or not.
Fluid level OK from factory statement has me concerned. Having done a filter change and fluid service fill procedure on this model transmission, I am highly suspect of a replacement coming with enough fluid and not any top off was needed for a level check.OP here. Transmission replaced, under warranty. Internal issue in trans. Here's the invoice with everything I know. It shows the codes and a simple, if not brief explanation, which is significantly more information that any personnel at the dealer were able to give me. Zero communication by my "service advisor", or anybody else at the dealer. Did not return any of my calls or messages. No updates, no status, no diagnosis, no "sir, we're changing the transmission in your vehicle, here's how long it will take, here's why we're replacing it, etc...." Just one call to me telling me to come get the truck, 2 hours before they closed. Truck at dealer for 3 weeks. Super happy with the dealership experience here. NOT.
Hmmm, but these run fluid through a cooler and some long lines....... What about any fluid that goes into any lines or cooler? Aren't those going to be "empty" (well, full of air, void of fluid?)
