Transmission Reset

I just did the trans reset and it worked great. My car had little trans quirks
in different driving ranges. Now it shifts perfect. I drove it about 15mi at different
speeds and I hit passing gear a few times and then drove around the hood coming
to a stop and pulling away slow but steady. Now I'm a happy camper

Insert the Key to into the key fob (DONíT HOLD THE BRAKE).
Press the Start Button ONCE, just so the car electronics start and show the Engine light is on. (Again, Donít START the Engine).
Press and HOLD the GAS PEDAL all the way to the force down click on the gas pedal for 25 seconds.
After those 25 Seconds, proceed to Starting the Engine and drive your car.

There is no conformation for this u won't get any message or beep. But it is real. U must make sure it's 25 secs tho exactly. Works for most cars with adaptive tranny. For some ppl it works for some it doesn't. And as I know it's not permanent. Hard shifting will come back.

I could tell by the way it shifted. It was smoother and more precise. I don't care what anyone says it work
on my car and it was very obvious. I was skeptical but tried it anyway and it worked. I didn't wait exactly 25 sec.
I counted 1000 1, 1000 2 and so on until I hit 1000 27 to make sure I was at least 25 sec and it worked.
who woulda known

when I did this, I drove in stop and go traffic at speeds from 25 to 55 mph for about 15 min while not getting into it at all.
Parked the car at a store went in for about 30 min -came out started the car - got back on the road and then I got into
passin' gear 3 to 4 time and went home - it was all good - don't know how long this will last but i will report back in a week
or 2 and let you know if it still seems to shift as well as it is doing now.

reset

I love your 7 what a great color and wheels
How long has it been since you reset the trans because I've read
that it needs to be reset ever so often. mind has been over 200mi and
still shifts like a champ. I wonder what other little tips I can find.
My audio (radio) volume will not turn up half loud as the CD volume, any
thoughts on that.

it works bros. i do it all tha time dependin on how i wanna drive this baby. if i got my lady friend in the car i do a reset and then take off gently so that i maintain nice smooth shifts when i pick her up. the downside to the smoother shifts is that the car feels slower especially when takin off from a red light and u gotta keep on drivin mad gentle if you wanna keep your smooth shifts. when i wanna drive like i stole it i do a reset and floor it everytime i take off this makes the accelerator respond better and the car feel like a 335i but it shifts harder and chugs gas like a muthaf. if you drive both ways without resetting it, you get weird quirky shifts

This was posted back in 07 and is one of the most viewed threads in the E65/66 forum:

http://www.bimmerfest.com/forums/sho...d.php?t=195020

I used to do it in my 545i quite often and have done it a few times in the 750i. I have always thought there was a subtle change, but who knows, it may very well be a "placebo effect".

It's not bs, it will reset adaptation and you should notice the change immediately in shift points while driving.

No, Its putting the car in SPORT Mode. From what I have read there is no memory to how the car drives it does not learn. Itdoes have 5-7 different styles that the car chooses from depending on how hard you put pressure on the gas.

Just to clarify, after the 25 seconds we let go off the gas pedal completely and hit and hold the brakes while pressing the start button?!?!

I tired the tranny reset. I instantly get the transmission fail safe switch when i try to put it into a gear. The code is a p0751. I checked fluid and it is full. Any other suggestions.

there's many threads on this. tranny reset does nothing to permanently fix the issue. i will make a guess your tranny is over 60,000 miles. more than likely, the tranny is just getting worn down. there is no fix but a new tranny or just change your driving habit so the tranny doesn't have to work so hard during rough braking or 1-2 takeoffs.

I've been doing it since I learned about it in 2008. It works for me and I've never gotten a fail safe warning. Say what you want, it's real for my 7.

I highly doubt the transmission reset will clear the check engine light. Try the reset and report the results.
