Tranny Speed Sensor Location

Hi guys, I belong to the E46 forum originally since I drive an E46. However I have a friend with 2001 525i. His speedo stopped working and tranny light DSC, SES lights are on. I pulled the codes P1747 and P0500... Then I did a quick search in this forum and I am hoping that replacing the tranny and wheel speed sensors would fix issue. I am hoping that it wouldn't be his ABS sensor.
Wheel speed sensors are no problem. But I was unable to find a DIY for the tranny speed sensor.
Can any tell me at least where it is located please?

I am hoping it is a doable job for home DIYers

Thanks

From my research into this issue when the ABS module failed on my 2002 530i, the speedometer/odometer use a signal from the driver side rear wheel speed sensor. I don't think an issue with the ABS module would throw the SES light. Sounds like the car may have more than one unrelated problem.

Wow... I still don't have any reply telling me where this sensor is located. I searched the web but didn't come up with anything. I did replace tranny speed sensor on other front wheel drive cars. It would always be mounted directly onto the tranny body. But those were front wheel drive cars so everything was accessable thru the engine compartment.
I was hoping to find somebody that replaced this sensor and tell me where it is located...

jcvara, I didn't pay so much attention to my friend's dashboard; his ABS light might be on as well.
This issue is wheel or tranny speed sensor or the ABS module issue. If it is the speed sensor, should be easy and relatively cheap. If the latter, then it will be kind of expensive... Your white smoke should have nothing to do with this issue. It is totally something else. Are you losing any fluid in your car (engine oil, coolant etc.)? Smoke usually means your engine is burning something it is not supposed to be...

If it's a manual transmission you most likely don't have a tranny speed sensor. The wheel sensors do all of the work. If one is bad the ABS will light up.
If it has an automatic tranny you might find the speed sensor mounted in the tail shaft of the tranny.

Oh yeah I should have mentioned that it is automatic...
So you are saying if we get under the car and look toward the rear side of the tranny we may see it?

Well we will see. He didn't order the parts yet. We have a few more days to search...

I know the fact that at least one (might be more) of wheel speed sensors bad. His SES has been on for that for a long time but this tranny light came on a few days ago...

These two pdfs will help. One shows the general location. The other shows the wiring harness connectors so that you can follow the wires to the turbine speed sensor and the output speed sensor.

Thank you for those pdfs rdl. They will be very helpful for sure...
I found the sensor on RealOEM diagram. As said it is located toward the rear end of the tranny body. We will have to get under the car to see if it is easy to replace...

If it's a ZF 5HP18 tranny it's inside the tranny mounted on the valve body. Drop the pan and filter to get to it.

Thank you so much for that picture. By looking at it, I can say the speed sensor is not accessable w/o removing some cover parts.
I was thinking it is directly bolted to the tranny body and is easily accessable. I guess I was wrong...

When my R/R wheel sensor failed, I had an engine code P0500.

If the ABS light is on as well, I would use one of the excellent DIY's Bluebee has put together and thoroughly check out the ABS system first....very simple and quick check of the wheel sensors.

I'm gonna make this thread the canonical transmission speed sensor thread in the bestlinks so others can find this information more easily.

- How to locate, test, and replace the speed sensor mounted on the automatic transmission (1)

To further flesh out the intent, am I correct in assuming that the right front wheel speed sensor gives vehicle speeds to the automatic transmission and that the transmission mounted speed sensor gives transmission "speeds" to the transmission?

What transmission speed is the transmission mounted sensor actually measuring?

Yeah it has been a while for this thread and I totally forgot about it. I received an email notification today (bluebee posted something...) so I remembered it.
Since I own E46, I didn't monitor this thread and eventually forgot.
Just a quick update for those of you following this thread. My friend fixed his issue soon after I started this thread. The main issue that was causing the Transmission code and ABS light was the ABS module. We removed the ABS module (very easily accessible in E39s sits right under the hood). Instead of buying a new one (very expensive), we decided to get it rebuilt. There is a company doing this. Forgive me I forgot the name of it. They did a good job at a reasonable price and provided 1 year warranty. We got it in 10 days; installed it and all the lights went off about this problem.
His SES came on shortly after that but it was totally a different issue.

He drove the car for about a year and then sold it due to high maintenance cost...

Any way to test the transmission speed sensors without removing them? Test resistance at the pins? What should they read?
Perhaps the connector just needs a bit of a clean out / disconnect - reconnect etc
Cheers,

The trans speed sensor is located on top of the transmission and requires the removal of the trans to access the sensor

I'm relieved that it appears both the sensors on the ZF5HP24 transmission are accessible once the pan comes off.
I wonder if there is a way to test them with basic equipment...

The speed sensors are nothing but electric coils wound on an iron core, you can check them with an ohmmeter. For 5HP24, the resistance should be between 290 and 360 ohms.

need help with transmission 01 e46

hi guys this is the first time I have posted anything but here goes.....I bought a 2004 325i about a month ago, had to do a few things to make it road ready and once I did she sure was sweet !!! that was until last Sunday morning at about 6:30 somebody slammed into the back of my car as I was doing 60mph. they totaled my car and kept on going leaving me sitting in the middle of freeway trying to figure out what I hit. It was the hwy patrol that stopped that told me that I was hit by a fast moving black Mercedes benz, said an eye witness called it in but did not provide a plate number. Lucky me.....Anyway I bought another 325 the other day one that needed the good parts that are left on my first one. The whole deal was strange with the purchase of the seconed 325 but I ended up getting it for 725.00. But it has an issue with the transmission. I had the car towed home because it would not go into gear, turns out the linkage was disconnected so I hooked it up and started to take it for a drive to see how it ran but when I took off it went right into 5th gear and would not let me shift into any other gear but reverse. Also I now have multipal lights on my dash and one of them has a gear like symbol with a ! in the middle of it. can somebody please give me a clue as to what it may be.
