The current MT's used in the 3 series are designed by ZF. Some 325's now 328's are built by Getrag using the ZF design. The 330 now 335 use the true ZF 6 Speed MT. Getrag is now partially owned by Ford known as GFT,,, Getrag Ford Transmission. The 328 gets the new GM six speed, the 335 gets the 2nd generation ZF 6 Speed know as the 6HPTU (Technical Upgrade) which among other features includes significantly faster shift times

Replying to: proeasy1 (Dec 20, 2006 4:15 pm) I've got one of the 12 (well, maybe a few more) Lincoln LS's with a manual, and it's a Getrag. Now I know why. My most likely next car is a BMW 3, so it's good info for that as well. |

| Over the last two days I test drove the 328i, 328xi, and 335i models at my local dealer. All with six speed auto transmissions. Entering the dealer yesterday I was going to get the 328xi for my wife as we live in the Northwest and have some significant winter storms lately not to mention our typical winter weather pattern and mountainous environment. Anyway, my wife said she'd feel better with the AWD. The 328xi drove well and the auto transmission was smooth with well synchonized shift points. The transmission's sport mode changed the character towards performance enough that it provided a spirited drive. I thought it would work for us....until I drove the 335i. The character of this car is so different and the performance so keen (acceleration is similar to the 911 I used to own though handling is much different)that it is a completely different car from the 328 model. The auto transmission on the 335i provides lightening quick shifts; I didn't even use the paddle shifters since the transmission in sport mode was all I needed at least during an unchaperoned test drive. Driving in a moderate rain, the rear end didn't step out though the rear tires "chirped" a couple times from launch. Not a race car but a thrill to drive nonetheless. I ended up buying the 335i. My advice: don't test drive it if you can't buy it because you'll only leave the dealership frustrated. My only concern and its partly ameliorated because of BMW's 4 year/50,000 mile full service coverage plan is about the durability of the twin Turbos. To my knowledge, BMW has only produced turbo engines for its racing program previously. How they'll hold up after 100k or 200k of "regular driving" remains to be seen. | |

Replying to: couloir (Dec 20, 2006 6:33 pm) BMW has been making Turbocharged Diesel engines for the European market for years. They even made blown gas engines a couple decades ago, although those too were only for the European (and Australian???) market(s). In the past, I've had turbocharged engines and I've never lost a blower, even with more than 100,000 miles on the clock. My secret? Synthetic oil. Turns out that's one of BMWs secrets as well.  Best Regards, Shipo |

Replying to: couloir (Dec 20, 2006 6:33 pm) I think BMW is keen to the competition and is stepping up the pace of improvement, don't you think? Interesting you compare it to the 911 as I was using the C4S as an example of what can be done with a great awd setup in recent posts. Have all the luck and safety in your new ride! Regards, OW

Replying to: magilla895 (Dec 25, 2006 6:15 am) What ride(s) are you coming out of or have experience in? How do you rate the 335 vs. others? Some have compared it on par with the outgoing M. Regards, OW |

Replying to: nkeen (Oct 15, 2006 6:04 am)  300 lb-ft made by the 335i). If I'm correct (and the Corvette's six-speed auto has the exact same features as the one BMW puts into the 328 and Z4 cars), then "too much torque" is not really an issue for that transmission, especially in this application.

My son's 2000 3231 automatic twice leaked largepuddles of what appears to be transition fluid ( although it is dark in color and smells a bit of oil ). Both times the quantity of the leak was significant, about a pint or so, and was located under the engine on the drivers side, just inside of the drivers side wheel. In each case it was on cold mornings. The first time the car had warmed for about ten minutes and when I put in in reverse and it felt like the emergenct brake was on. after reving the engine it seemed to break free and drove well after that ( I didn't see the oil puddle until returning later in the day. On the second occasion, same thing but this time more fluid and then the car would not engage in any gear....again, another large puddle of fluid. One mechanic power washed the engine and could not find any significant point where it leaked from. I now have it into a BMW service center and have refilled he transmission fluid and the car drives well and....no major leaks!! Some minor ones at rear main seal and topside shift shaft seal. They are miffed....will be replacing the frozen Vent valve and feel it might have something to do with building pressure in the engine and it being somehow related to the leaks.......? Anyone have any insight to this perplexing issue....? Many thanks for any and all replies. tbysea |
