Hello to everybody.
Im new to my Bmw 1998 740i with 165000 miles
First at all sorry for my english but i will try to explane my problems.


First one :

When I put D and start driving all gears shift smooth 1 to 2 to 3, but when im going to stop it goes good from 3 to 2 but then sometimes from 2 to 1 it seems like it doesnt change and stock in some position, and car stops immediatlly without pressing brake pedal, and then when im trying to acelerate it feels like some one pressing a brake pedal(not too hard) same time, any ideas???
and main thing when you put on S (sport) everything is good
Second one:

Helpppp guys, cauz closest bmw shop are 200 miles from me..

for the shifting maybe this helps,a buddy of mine has the same problem but only if on of his tires didn't had enough air,he filled it up with some extra air at a gas station after that no shifting problems happens a couple of times in a month hope this the case for you also good luck as for the sound wouldn't know what it is also you better of asking the guys at the E38 section

thanx, im already posted on e38, i will try it))

Reset your trans. If you need instructions I will post them. Mine does the same thing, I think its just ****ty transmission design in all honesty..... Mine does all sorts of stupid stuff and its only 2 years old.

As for your video, TAKE IT IN THE DAY! A sound issue is hard enough to find, but it doesn't help that we cant see anything either!!!!!

please post how to reset transmission cauz unplug possitive and negative and put them together doesnt help.
I went to some shop and listened with some tools and said tha its steering pump

Put the key fob in, push it in so the electronic come on but don't start the car. Push the gas pedal all the way down (you may feel a slight click) Hold it down to 30 seconds. Release it. Start the car and drive it around and see if it helped.

Here is another link on video
also when i removed engine cover i have found an unplugged connector, what is it??? it is in the end of video

thanx for help with transmission, it helped me. now it work more smooth then before

I just realized that its a 1998, your in the wrong sub-forum buddy. That knocking is prolly a bad header. Not sure what that connector is for.

i dont even know if that trans reset works for that year.

I know but there are people who had this car before for sure. Yes it helped me with transmission reset, it does made click noise and transmission work much better right now.

you mean exhaust headers???

That wiring and connector look like they go to the sensor on the air box (the plastic around the air filter) that reads the intake air temperature.

As far as the other issue, I'd take it to a transmission shop and have them check it out. If it is only doing it on Drive, and not when it goes into sport mode, then I'd imagine that it is something wrong with your transmission. Some shops give out free diagnostics when you bring the car in, so I would get out a phone book and start calling around to see which shops offer this in your area, then I would take it to all the shops that do, and see if I got the same diagnosis at each shop. If all of the shops tell you the same thing, then you've probably found your problem.

Sorry, meant engine rods, Im not much of a tech once you get to the actual engine. I can do performance mods and basic maintenance. But my knowledge goes down at this point, lol

engine rods....mmm sounds terrible

and one more thing you can hear this noise until it low then 1500 rmps after that everything good
