Hello I am trying to locate my transmission speed sensor on my BMW [X3](/topics-x3/) 2008 Mechanic's Assistant: Okay, I'll connect you to the Mechanic to help find that for your BMW X3. Before I do, is there anything else you want him to know? No I just need to know where the sensor is located at


Please help ASAP

Hi. I'm Daniel, I'll be the mechanic assisting you today. I'm sorry to hear about the issue you have with your X3. Let's see if we can figure this out and get you back on the road quickly. Most likely the transmission speed sensor is located "inside" the transmission. Can you send me the VIN from your car so that I can check this for you?

one momentalso my husband and I have been searching for days for the speed sensor so if you could FaceTime us and show us specifically where it's at that would be awesome as well hold on and I will give you the Vin numberWBXPC934X8WJ06198Can you send a picture of where the speed sensor is generally In the transmission
Automotive Expert
Thanks. Please give me few minutes to look into this. I get back to you with the information I have as soon as possible.

Okay we are Under the BMW now
Automotive Expert
Thanks for waiting. Your car has a input and output speed sensor. Both are located _<u>inside </u>_the transmission and attached to the mechatronic module. To access the sensors, the transmission oil sump needs to be removed. This will give access to remove the mechatronic unit itself as the sensors are located on top of the module. I added a few pictures for you. I hope this helps at this point, let me know if you have any questions or concerns.

Hello are you still available we need help

Hi. I'm about to sign off for today. If you have any questions regarding the transmission speed sensor let me know.

we put it in and now it won't go into driveOr any gear what did we do wrong
Automotive Expert
Have you been able to re-fill the transmission according to the manual. In addition, did you use a OEM part as replacement and are there any relevant fault codes stored now in the EGS (transmission control module)?

these came up on the dashboard

Exactly do we put the transmission fuel at
Automotive Expert
You would need to hook up a scanner to read out the stored codes. However the warnings indicate a issue on the stability system and this may not be related.

Do you think that we hooked something up wrong when we put the part in
Automotive Expert
This is hard to say as I can't see the car myself. If you are in doubt you can re-check your work. Also make sure that you fill the transmission correctly afterwards.I won't be online today anymore but able to assist you further tomorrow if needed. Hope you have the car back on the road soon.
