My car has 90k miles do you guys think I should get my transmission fluid and filter changed? Just to be safe? Thanks

Auto or manual? Regardless you should change your fluid and if you have an auto change the pan and filter when you change the fluid. Change it yourself with the diy guides on this forum.

Auto. I'm not that experienced with DIYs . You think it's doable?

What a coincidence. I have the same year and model BMW. Just a couple months ago I was in the dealership to get my oil changed and since I was near 90K miles at the time(just broke 91), I asked about the transmission fluid being changed. He informed me that it would be a good idea to have the transmission flushed, getting a new pan/filter and topping up with new fluid. Cost at the dealership ran something like $600+ if my memory serves me right. I'm definitely getting this done as I plan on keeping my BMW for the long haul, but not without checking with the local indies in my area. Hopefully I can get a better price. I definitely think it's a good idea to do after all the miles we've clocked in. If it's one thing you definitely don't want to f**k up, it's the transmission. And just as a side note, have your water pump checked too if you haven't already replaced it. From my recollection, the average life on it's right around a 100K give or take a few thousand miles.

Yeah I experienced the water pump . Went out at 85k miles when I was on the way to get my tints..funny right haha. But $600?? I thought it was around 150-200?

Its quite easy. I see you are an 06 3 so you will have to see if you have a zf or gm transmission. Choose your fluid off that.

What's zf and gm transmission?

[Averdi]

Would this be everything I need besides the fluid?

[135Pats]

Yes. IMO pair that with Redline D4.

Also you should swap the mechatronic sleeve while you're at it. Takes an additional 10 minutes, but is very cheap insurance. I would not be surprised if your's has started to leak and crack at that mileage.

I just did an AT service at 50K. Well worth it, I will probably continue to do it every 25-30K from here on out. The ZF box on the E8x/9x/6x is pretty robust, but clean fluid is good fluid.

So why are people saying a transmission change can go up to $800?? If all you need is a $100 part and $80 I'm fluid?

If someone tries to charge you $800 in labor for a transmission pan/gasket swap, fluid swap, and mech sleeve swap…you should laugh at them, to their face.

It’s DIY, or an honest indy can do it without too much trouble. It’s not like we’re replacing the valve body or head gasket here…

I don't know if I could even DIY. I've never really done anything except swap angel eyes haha. I would like to try but I just don't have the tools or jacks

And what is the "pan" In the transmission? People say to get the switched out too

I believe it is the pan gasket. The pan itself is doesn't need to be changed.

I used the below DIY instructions on my daughter's '07 E90 when she was just under 100K. She now has 115,000 miles.

This is not a DIY for the faint of heart. Steps 11 through 16 are done while the car is on four jack stands. I am not a fan of being under the car while the engine is running and it is on jack stands. An indy with a rack could knock this job out in less than an hour.

The pan is that part you pulled up on Amazon. Quite literally, it is the auto transmission fluid pan. Same as the oil pan, just obviously a different fluid serving a different part of the car. The gasket that lines it cracks and hardens over time, hence the need to replace the entire pan. Personally, I don’t think people care for the AT as well as they should. I think it’s loony to go 100K without doing anything in terms of upkeep. If you are bone stock then I guess it’s different in terms of the heat you are putting through it…but regardless. Service it!

Okay thank you. I guess I'll have a shop do it for me. Better safe then sorry

I will. I just don't have all this money laying around. Only 18 paying for everything myself. Sucks but rewarding. How much you think it will all be in the end?

[The Cleaner]

Don't waste the money changing the fluid if you are not going to drain the toque converter. A drain and refill changes about half the fluid, I know there are a bunch of people that think it's a good idea anyway but I dont see the point if you dont changed all the fluid.

What else will I have to do if I would want to change the torque as well?

[Averdi]

You guys don't think it's too late to get it done at 90k right? Any suggestions

What do you mean “too late”? It’s never ever a bad idea to service the transmission. It’s not like you’ve fried the clutch packs, you’re just trying to keep things in tip top shape. I don’t understand your concern here.

Ive been doing a little more research and same people say if your car is at higher mileage there is a possibility that crud that has built up in the valve body may be softened and dislodged … only to jam another area of the valve body.
