look for a module on the side of the tranny. they seem to go bad.

 

Any specific module? I have little mechanical knowledge and my mechanic is kind of lost on this subject matter also. He thinks it might be a solenoid, but he's not sure. Realistically, I don't want to replace a bunch of parts until I get the right one. Thanks.

 

.....and my mechanic is kind of lost on this subject matter also. He thinks.....but he's not sure................

First........replace your mechanic! Seriously.

You haven't given much information, but I'm guessing your mechanic has very little experience with BMW's. Find one that does. You don't say where in PA you are.

If you don't know of anouther mechanic near you, then browse the following link http://www.bimrs.org/ to find one near you.

Buy the Bentley two volume service manual. Google it to find a source. This will be your bible to maintaining your car.

Good luck.

 

any more input? i'm having a similar issue.

 

I seem to have fixed my 3rd to 4th shift problem with cleaning the right rear wheel speed sensor. Not to mention
that my ongoing ABS/DSC/BRAKE nightmare has since vanished. (knock on wood)

 

nice.

 

I was wondering if you solved the problem i have the same problem with the same exact code????

 

hi
i have the same problem bmw 525i p0733
did you rcv any solution from any one??????

we know that already. we need to know what part needs to be changed

Similar Issue

I had the same issue but I replaced a front left abs wheel speed sensor. The speed sensor looked fine but when I put the new one in it shifted like a new car.

 

Do you fix the problem?

 

What's funny is that people think a code implicating a sensor means to replace the sensor.

What the code means is that the sensor is measuring something that isn't right. It could be its voltage or it could be its input or its output, but a code does not automatically mean "replace me".

It means "something is not right here".

 

Agreed. The problem requires diagnostic skills. The link suggests some potential areas for investigation. http://www.obd-codes.com/p0733

P-codes are not like cookbooks.

 

parts changers drive me nuts.. the scary part is some 'professionals' do the same thing..

 

Agreed.

Diagnostics to test a part often take more time than just replacing a series of suspected parts.

Professionals use the excuse that they're trying to save THEMSELVES a lot of time because saving time on your car means they get to shove more cars in their queue.

Professionals also have the advantage that they have a much larger stock of readily available parts lying around in inventory (which they'd like to get rid of too, for the same reason that inventory is supposed to "flow", as in "cash flow" (from you to them).

Professionals also have the additional incentive that they get to CHARGE you for everything they replaced, whether you needed it or not, even if they replaced it only for diagnostic purposes (it would cost THEM time if they removed the part that turned out not to be the problem, and they wouldn't get paid for the effort).

Some professionals even use the excuse that even if you didn't need it, you were going to need it eventually.

 

Okay I have a1997 528i. And also had the same code.
The following issues could cause the this code.
1. Bad ABS wheels speed sensor
2.. Bad battery
3.. Low transmission oil.
4.. Bad shift solenoid.
Now the fix.
If you don't have your ABS or ASC light on its not a bad ABS WSS.
2. Test your battery if it's over 4 to 5 years old replace
3. Time to change transmission oil and filter.
All the above work for my case.
Finally my 5er started to shift hard and started to slip.
So I highly recommend you go ahead and change all of the shift solenoid at the same time you do the ATF and filter change.

You can find the shift solenoid set on eBay for under $150.

 

P0733... glue monitoring....(incorrect ratio 3rd gear)

so this means your output speed sensor gave up in 3rd gear.
change speed sensors.

Speed sensor circuit malfunction can cause limp mode, stuck in gear, gear box light,etc....😌

 

Change speed sen

I have a 1997 528i and the engine must rev up to 6000rpms before it shifts out of 3rd gear and into 4th briefly and then into 5th immediately. The engine code is P0733 which is gear 3 ratio incorrect. Can anybody point me in the right direction on where to start with this problem? Also, the transmission is not slipping. Thanks in advance.


Change speed sensors. Its a output speed sensor circuit malfunction.

 

Remove the wheel and clean the speed sensors and their connectors, before resolving to change it.
