I kind of thought my 8 spd transmission had issues, now I'm kind of thinking it is....

[ShadowsPapa]

Mine runs impressively smooth ... that has actually been one of my praises of this 8spd. You might confirm oil level ... you mentioned being a 2022.... mines a 20' ... I opted to do a dump and flush at 30k miles. I do not for a second buy into the lifetime fluid that Jeep claims, especially when the ZF documentation conflicts. Not all will agree, but I do spend some time off-road and also towing ... it was not that expensive to have my dealer perform the service and they also agreed with my sentiment of the lifetime fluid.

.... now if you want to experince a hard shifting trans ... drive the Ford 10spd .... that thing is possessed!

Remember, lifetime has multiple meanings depending on who is using the word. Assuming they expect it to last 100,000 miles, yeah, it's lifetime. For an owner who wants it to go farther, it's a dumb term.
No way I need to do it that frequently - 30K is nothing for me and my driving and use of the truck. But....... lifetime? Hmmmmm. Define, please.

My differential fluid levels were fine. About 1/2" down on the front, about 5/8" down on the rear. Fluid looks fine so far - but that's only 10,000 miles and one trip towing so it's not really had any hard use at all (other than a long drive to Fl and back last fall)

Fun on transmissions - 4,000 miles on the GERMAN-built ZF in my wife's Jeep (while the transmissions in my 2020 and my 2022 remain totally dry - totally) ->

The 850HP is definitely not the diesel transmission. The diesel gets the 875HP and is not built under license to my knowledge. The 50HP is used a lot in BMWs and comes in a couple alfas.

Sorry I mistyped. The 3.0 eco diesel gets an 8HP75. From what I can tell, the transmissions designated “8HP” are made by ZF, and the versions starting with 850 are the fca license ones. The 850RE & 845RE are both manufactured by FCA and performance specification wise identical to the ZF manufactured 8HP50 and 8HP45. So to answer your original question the 850RE is manufactured by FCA and the 8HP50 is made by ZF. Keep in mind depending on license agreement a licensee may have the freedom to make small changes, like additional lugs in the casing housing to accommodate specific mounting locations. But the fundamental item has to remain the same.

 

[ShadowsPapa]

The 8HP simply means 8 speeds, hydraulic, planetary. The number of course is torque rating.
The jt units are made by FCA.
ZF could not supply quantity fast enough.
So jt and jl units are not manufactured by ZF.

Sport Max Tow. I'll be at 4,000 miles in about an hour.

Will have to read up on how to check the transmission fluid level now...

I have a max tow, im at 10600 miles., 2021 Model. Mine did this too in stop and go traffic, still does it sometimes from third to second, but its more of a gear down then a thud IMO, but it can be a hard and abrupt gear down.

Im in stand still traffic every day. I work 8 miles from work and its 20-30 minute drive in the afternoon.

I always like comments that say , BMW's have their issues, about every friend we have owns a BMW of some sort. My wife And I alone have owned 7 over the past 16 yrs and not one has ever given a issue. A couple we put over 200,000 miles on. I currently own a 2013 BMW 328I Xdrive coupe with 158,000 miles on it and the Wife has a 2016 BmW X5 50i with 78,000 miles. No one I know has ever had a issue with them. You stay up on the maintenance and they are solid. I've own about every brand you can think of since 1996 when the wife and I got married. BMW's have been the most reliable of any brand and that's including the one Mercedes we had in 2014.

i stand by this comment. if you do the maintenance, BMWs can be a decent car, but you have to have the money to maintain them and they are expensive in my area. Id say this about kias too and kias are absolute garbage. Most of the friends that i know that have bmws cant afford proper upkeep, hence the reputation. My well off friends dont have as many issues. I have one friend that only buys Land Rovers! LMAO.

Your mercedes you just got lucky, but i digress. Glad you had a good experience with that brand, rare in my experience.

Piggy backing off the "relean/learn" that these do. Mine had a weird hesitation in 3rd at ~2000 rpm. It seems like the TC slipped then slammed itself shut leading to a jolt. Took it to the dealer, told them about it, the advisor said its 3 weeks out for a transmission appt but would see what they could do. They initiated a re-learn and so far, all is well. I drove mine back from Springfield TN to Atlanta, so the first 300+ miles were highway, and could have led to the weird lower gear issues I was experiencing.

@ShadowsPapa Did you ever determine if you could do a hard re-learn through J scan? Or is it only possibly with the dealer tech tool?

Define expensive because the general maintenance you got to do to keep them running properly like change out the plugs and coil packs on schedule and do the oil changes every 10 months really isn't that expensive. Also running the right fuel in them and keeping the air filter changed out. If you do these simple things a bmw will run right for as long as you own it. I've put almost 300,000 miles on 2 and the persons I sold those BMWs to are still driving them. I got 156,000 problem free miles on my 328i. I don't think you can call it luck if you've owned 7 and never had one issue. I have Owned 8 FCA products and had to have a buy back once on a 2013 jeep grand Cherokee that had a blown motor at 2500 miles. 2 transmissions in my 2010 JkU, one at 59,000 miles and another at 91,000 miles.

Old BMWs (looking at you n54/n55/s54/S55) were atrocious to maintain, injectors for the n54 alone at $800 a pop because they're not made in mass anymore. Now, the new engines, b58/s58/s63, etc, are not bad due to the mass production of engines and parts. Plus, they are significantly more reliable and easier with upkeep. no more vanos issues, worn bearings (except some random s62/63 issues). Expensive is relative as always.

That sounds fairly normal.

At one time I thought I had seen that it could be done - I'll have to revisit that because I'm curious again.
After driving my wife's 4xe for hours at a time through all sorts of terrain, I'm thinking that a lot of what people see as "problems" with the 8HP is actually lack of torque from the 3.6
The 4xe has a lot more torque and HP than the 3.6 - even the 2.0 alone, apparently, as pointed out by a member here, has more torque and HP than the 3.6, albeit on a very different curve with a shorter peak. You don't see the gear drop-downs, or hunting at all with the 4xe. It just isn't needed. The 2.0 even without much assist, can take hills the JT 3.6 needs to downshift for. The 4xe can maintain 8th gear against a wind that causes my JT to drop back to 6th and STAY THERE for miles on end.

So I'm convinced the transmission in the JT is making up for what the engine can't do or handle.

I haven't had much experience with the older ones other than a few guys I know with really old ones, like early 70's models but they seem to like them. As far as maintenance, I mean on the straight six twin turbos, 6 coil packs and 6 spark plugs package online for $180 and you can do that work yourself. Dealership charges $565 to do it, that's every 80,000 miles. That's about the most expensive maintenance part. Oil change is like $140 on rhe straight 6 and $210 on the Twin turbo V8 if the dealership does it. All reasonable priced maintenance that you can also do yourself once it's out of warranty. Coil packs and spark plugs package kit for the twin V8 runs $212 online and every 80,000 miles. I think over the years people just assume the maintenance is super high on them from back in the day but now days it's not much more than a standard vehicle. It was pretty much the same as my 2017 Mustang 5.0 we had as far as maintenance cost.

Lets take the obvious and start at labor rates. BMW used to use some weird time keeping when i worked there 20 years ago, but thats the first thing i think of being more expensive than a Jeep labor rate or a domestic model.

Price brakes and rotors on a BMW then a Toyota or a Jeep.

Price labor for a radiator on a bmw 745.

at my dealer, brakes in labor alone are $350 JUST in labor, that is expensive in my opinion.

To keep with the science/data, i make less than 90k a year, so my relation to expensive may not match yours. My jeep is out of reach for alot of my friends.

BMW, Mercedes, Land Rover, Jaguar, Porsche are all vehicles I know are expensive to maintain and harder to work on (maybe meticulous should be the better word) that i want to deal with/pay for. i priced some cadillac brake pads that were $478 dollars. Thats expensive to me for brake pads. BTW, it was NOT a CTS big boy caddy.


My father in laws amg550 was hot garbage, absolute garbage. HOWEVER, id kill for an 80's mercedes, old diesil anyway

considering your previous vehicles, i can already tell you are above my tax bracket.

my fil in way above my tax bracket too, 500 dollars to him is 50 dollars to me. maybe im cheap

edit: i did not take in to account aftermarket parts/ im stating factory work at a dealer.

I just did the coil packs on my 2013 328i and it took like a hour or less and cost me $160. It's easier to do them on the BMW than it was on my 2010 JKU. Plus brakes really, they want $500+ to brakes on anything at the dealerships around my area. I got a guy that does my brakes for me and I buy the parts and he does the labor. Less than $400 to get it done on any vehicle. Your logic doesn't seem logical just like trying to gauge my tax bracket based on the cars I buy. My wife's a upper manager for atrium Health and I am operations supervisor for a lumber yard and I have a full time cleaning business that employees 18 people. Try adding up that income. I buy what I like to drive as far cars go but trust me I could afford a nicer car if I wanted to but I also am planning on retiring in 5 more years when I turn 50 so I like to keep the spending in check so I can play golf everyday after 50.

Sounds like mine. You describe it better than me probably.

thats not at all what i was trying to say, my apologies.

I was using it in a relation to our perception of money. I dont think you are wrong or i am wrong, i think our perception of money is different.

Again, my apologies, i wasnt trying to be like that or be dick.

Glad to hear you're killing it professionally. My wife is a teacher and i work in the automotive industry. My retirement plan is death.

EDIT: gearheads will notoriously spend less DIY'ing. I thought we were talking straight dealer services, so our comparison wont be even.

I can probably take care of a BMW if i did the maintenance with my knowledge and discounts easier than Suzy who just wants a BMW and doesnt realize its 160 dollars for an LOF.
