Time for a new transmission in my 2010 335d

I don't know if he experienced this but the first thing I noticed was that the car would surge a bit after I'd stopped - usually after I'd come off the freeway or had been using sport mode. It was like that for a while since the mechanics couldn't duplicate it and it happened rather infrequently.

Then on two occasions it popped out of gear while traveling at the limit on the freeway. The mechanics couldn't replicate that either; after it happened two more times on the freeway (not a particulary fun experience!) they took the car right away and soon told me I'd be getting another transmission. I had to wait a week or so since it had to be shipped from Germany.

So far so good.

This appears to be one of the first Tranny losses we've seen reported here.

If you've ever had a Auto-Tranny apart you can definitely understand what could possibly go wrong. It is a marvel of mechanical engineering.

Can't say our Tranny is any higher risk than any other automatic out there. Probably costs a lot more though.

Reminds me I need to get a quote on the extended warranty/maintenance soon!

425 Lb/ft. of torque has to put a bit of a strain on any tranny. Anyone know if the tranny in the 335d is any different from that in the 335i?

I believe it is different - someone here posted that it is also used in some of the 5 and/or 7 Series.

This thread probably has the details: 335d Transmission

Surprising to read about the trans fail.
Sorry to hear & glad you had coverage

My understanding is the tranny is very different than a regular 335i. I read (but don't remember where) the trans in the 335D was last used in the X5 4.8. Would make sense, as was probably the most HP/torque used in a regular automatic back when the 335D was being designed.

It is completey different and built to handle the torque and then some. 335d's built up through 8/2009 had the ZF 6HP26Z which was then upgraded to the more stout ZF 6HP28 which has a higehr torque rating. The ZF 6HP26/6HP28 is also found on the E65 7-series, E63/64 6 series, E53 X5, E70 X5 4.8i, and whole slew of other cars by other manufactures including Maserati Quatroportte, Range Rover Sport etc

Here is the manual for the ZF 6HP26Z/6HP28.

I am sure the transmission will handle the power of the car just fine.

I do think something to consider and no I did not go looking at any of those cars specs but something to consider is how the power comes on and where it hits. Back when I used to race Mustangs I used to always see people make the mistake of tossing a C4 transmission behind a turbocharged 302 ci motor. Their thought process was the C4 handled the HP and close to similar tq numbers with some bigger NA motors so should not be an issue. Those guys more times than not were always breaking their transmissions or having to freshen them up a ton more. They just did not take into account the differences in power generation and application. I only mention that because these 335d cars make a decent chunk of power but more importantly it comes on and peaks pretty quickly, must make for a rather strong transmission need.

As soon as I get the bill, I'll post the info. I was told to keep rocking the Mini Cooper S for another week while they wait for the transmission to be shipped from Germany. Apparently, none are available in the US?

Any time my car has needed anything, it was not available in the US. Half wondering if in a couple weeks when I take it in for an oil change and rear blinker fix if they are going to tell me it needs a part shipped in from Germany. Kind of annoying when it is smaller things that I'd expect to be common. I could at least understand for not so common things like transmissions.

I usually take Rt. 85 down to River Road then cross the river at the American Legion bridge and avoid 270 during my commute to NoVa.

I never experienced the surge you describe. Odd.

I wonder if my replacemed transmission was the upgraded one or if I got an exact replacement of the older model, since my car was built in 07/09. There are part numbers on the paperwork but they aren't those ZF 6HP26Z / 6HP28 numbers.

I am sure BMW replaced your transmission with the same model that came in your car originally since the part is sourced by VIN#, not to mention there might be other physical differences between the two that would preclude them from installing the latest gen trans, although I would have certainly asked for the latest. Proprietary BMW part numbers are not the same as a model number for a particular transmission so it doesn't surprise me they don't match.

While on the topic of trannys, but slightly different issue, was wondering if anyone gets a slight but distinct 'whine' from the tranny/tranny area around the low 70 MPH range? Notice it fairly consistently, when music is not too loud

Hmm, the only "Whine" I hear at about 70mph is my wife telling me to slow down!

Mine a few times has not fully engaged in reverse. Only happens when the car has sat for a very long time and is just first started.

Joe,

So what is the status?

We missed you at the first S. Fla. reunion. All three (3) of us!

Sorry was supporting a software install for a hospital in NY. Worked round the clock for a couple of days and got home late Friday night. I will make the next one.

Joe

So what did they conclude about this problem?

Took it back this morning first chance I had. Also Vista has a 1M on their showroom floor, $52K plus $20K MPA!!!

My d developed a whine at 70mph (not the wife, this time ) Turned out to be a failed wheel bearing, drivers side rear. 26k miles on the d, at that time. Later on, the wine would come on around 50mph.

A few times in the past month I have noticed a faint high-pitched whine just above 70mph. I wasn't sure if it was the engine or the transmission.

The conditions have to be just right in order to hear it, but with typical traffic conditions here that doesn't happen very often. I assumed it was nothing to worry about - I'll keep my fingers crossed.

I had this exact thing, replaced at 55,000km (left, rear bearing).

I hope they dont catch the JBD that spells trouble and they try to blame it on the aftermarket JBD, cross your fingers on this!!!! Sorry to hear your issue, wish I could get a company to give extended warraties here in Puerto Rico, I do not know of any here, if your company does so REFER them to ME ok !!! I am willing to get one. Gracias!!! Hey if any of you SNOWBIRDS(LOL) decide to come to the Island let me know in advance so I can come meet you and you can see my RENNtech mod in my car ok!!!

Wait, I thought BMW had a 5yr/60k powertrain warranty plus 4yr/50k B2B like Audi? Is this not true?
