Question Torque converter failing?

Hi all,

Sorry for bothering you just in my first post but I'd like some guidance. I've been reading tons of info in this site mainly and have had the chance to solve several issues with my recently bought X5 (about a month ago). However my main issue is related to my auto transmission ZF, specifically the torque converter as was I was told by the first mechanic who checked it. He suggested a fluid change, 6L of ZF fluid were put in it to see if I could get rid of a shredding noise while changing from 1st to 2nd gear coming from the front of the trans, I believe from where the TC goes. Also, the car will stick on 2nd gear after driving over 40 kms or so, no matter how gentle I drive it. When I have driven the car a lot the gear changes are not as smooth as when it's cold or not driven that much.

I'm so in love with this car that I can't think on letting it go that fast and since I bought it relatively cheap knowing the trans could need to be rebuilt then I still want to give it a try. It's just over a month with it and I have spent more than $1.200 to fix other issues and do the AT fluid change with oem filter and gasket.

My car doesn't rev up and down anytime, it just sounds "uggly" when it goes from 1st to 2nd gear I haven't heard it in any other gear change) and sometimes it jerks in a hard stop coming from 2nd to 1st.

I changed the battery about 3 days ago. Resetted the TCU, changed fluid with oem, including filter and gasket.

When the issue happens it reports an error (scanned with bmw software scanner on a PC) and it says in yellow "excessive torque converter slippage".

But I can't feel any slippage.

What's happenning?! This is driving me crazy and I'm starting to love/hate my X.

Does anyone have an idea about my issue? Or should I go straight away and ask for a TC change? What I don't want is to throw money on random stuff and then realize it was something else.

Thanks in advance!

Like a bad relationship, when there's more hate then love, it's time to move on. That's why the PO sold it for so cheap. There's no such thing as a cheap BM Trouble U. You either paid at the beginning or paid at the end.

Sounds like a rebuild is in your future. Either you have a crack drum or one of the o-ring needs to be replaced. In either case it means a rebuild.

It has 197kms, not sure how many miles are those.

Before it goes into 2nd gear after having driven it above 30 kms, my DSC goes off, I get the trifecta lights, then a few kms later it goes into 3rd gear if I'm on the highway and as soon as I slow down bc traffic or anything it goes to 2nd gear and stays there.

What I do is to pull off for a few minutes, the start the engine again and the story starts over again.

The only thing that worries me the most is that there is a metallic sound when changing from 1st to 2nd. It doesn't happen all the time, but it's there.

I will ask to check those sensors and wirings.

Thank you!

I always go for the -$100 fix before really tugging on those wallet strings....

Oh! BTW, The shredding noise is not noticeable or present when I change gears like in a manual trans, I mean, releasing the foot from gas then changing gear, then pressing gas pedal again. But, I didn't pick an AT to do manual gear changes if you know what I mean.

Anyway, I hope my findings might give you a better idea of what's happening and when it gets solved (finger crossed) it might also help others in the same situation.

Greetings
