7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

had/have the problem

My 2007 only has the problem in sport mode. Replace the tranny fluid and filter. Replace the guibo. It is better, but has still happened in sport mode. I have decide to keep out of sport mode as low speeds.

I never put my car in sport during normal street driving, only sometimes on highway driving and never have I once experienced that issue yet on my current 07 or previous 05. I would advise not to drive in sport regularly once u get the work done.

Interesting. My SA told me that if I changed tranny fluid that they would have to apply a "reset". And I guess that reset has an update for the tranny software? Does any of this make sense? Maybe I wasn't listening correctly.

I am having the same issue - please post any info on a reset after changing the fluid... I changed the pan, gasket, and filter after I noticed the pan was leaking.
Car feels like somebody rear-ended me at all stops!

I had an independent garage do the work. They didn't mention a reset. As far as I know, no reset has been done.

Did you do the second part of the fill procedure, where the engine is running and you again fill till fluid comes out of the fill hole?

On the reset topic: there is a "reset transmission adaptations" item in INPA. On one guy's drain/fill that I did, doing this cleared up a lingering sloppy shift/clunk that the gas pedal trick did not.

J-303, did you have the ratio monitoring gear shift 3-4 code like dunnrite11 or did you have a mechatronics code? I have the ratio code and was wondering if it could be the mechatronics problem. Dunnrite, did you get yours fixed? What was wrong with it?

Thanks,

Andrew

I don't remember. But after it was slamming it was getting out of gear as well. So I had the Mechatronics replaced & the seal as well. New transmission fluid. How many miles does your car have? Like I said after I replaced it no more slamming. Knock on wood.

Dunnrite11, the 3-4 code problem stems from the valve body....the slamming problem has to do with the mechatronics. I'm sending my valve body to Houston for repair today. I will post the results once it's back in the car but am confident that's all it is.

I thought the mechatronics valve body was sealed and could not be serviced? I think the "lifetime" oil gums up the valves in the valve block. Hopefully the slipping and slamming have not affected anything else.

Hard-shifting transmission

I recently purchased a 2007 750Li w/ 53000 miles on it. I noticed right away it shifted particularly hard from 2nd to 3rd gear fairly consistently. In Sport mode, it was more noticeable, and in Manual mode it was sometimes so severe it felt like someone rear-ended the vehicle. Since it still had some remaining CPO warranty, I took it to a local BMW dealer to see if they could do anything about it. I discovered that the vehicle had been serviced there by a previous owner for the same complaint. I call another local BMW dealer and they too had two service records for the vehicle for, you guessed it, the same issue.

Anyway, the dealer said they simply reset the adaptive learning for the transmission. Although I have only driven the vehicle several times since getting it back, I'll have to say the hard shifting has completely disappeared. Smooth as silk. We'll see if it lasts. I'll check in on the forum in a few months to provide an update.

Oh, by the way, BMW would not pay for the reset. Said it's not a warranty item. Oh well, it cost me $140 but well worth it (unless I have to keep taking it in periodically to have it reset again!) Keeping my fingers crossed!

Adaptive Reset fixed my issue when it was doing the same thing. I was diagnosed by dealer that it was torque converter and
quoted me almost $3500 for a new transmission (which comes with new converter). It wasnt until i had someone else look at it
and they did a tranny reprogram and reset and all was well. Every once and a while I get a hard shift when I come to a full stop,
but the tranny reset giving above has always made it smooth back out. Dont know why it reoccurs every now and then though.

I've been posting today because I bought a 2006 750I with 87,000 miles and have been living with the bang for almost 30,000 miles. Step 1, Replace the GUIBO Joint first. A good mechanic should be able to do it in 3-5 hours.
I just replaced my GUIBO joint and it was worn out to the bone. I took it for a test drive in S mode and it shifts like butter. I'm so happy that now I have the ultimate driving machine that if your riding with the bang, like someone just rear ended you, then this is a must fix before doing anything else.

Also, While your doing the GUIBO, have the mechanic pull the tube in the valley pan part of the valley pan gasket coolant leak,it will eventually fail, and replace the o-ring at the top of the tube. Since you have the tranny out, you can slide the tube out the back of the valley pan and replace the tube by removing the o-ring and then sliding the tube back in and putting the o-ring back on with windshield adhesive and let set overnight.

That's what I did while I was on vacation. The Indy shop needs a few days to do this.

Okay, so did anyone ever figure this one out? I have a transmission (750Li) that will slam after you reset it until you go to shift into 4th gear. it then revs really high, slams and then goes into limp mode and the code is 4F89 Ratio Monitoring, gearshift 3-4. Valve body? Mechatronics? Transmission?

I would start with the Transmission fluid and filter change and the Mechatronics adaptor maybe even the Guibo.
