Impossible. 6HP26 is only for V8 powered cars. It will not bolt up to an M54 block, which if you have an '04 or '05 525i or 530i, you have an M54 powered car.

I have a 550i with 6HP26. The transmission fault 4F89 sometimes 4F83. The sometimes symptom are:
When using normal D shift: when it at 40-50km/hour, the engine is at about 1200rpm and when try to speed up, the transmission is trying to kick down the shift and the fault generated at that time. When I drive at DS or Sport mode, this symptom has less chance to happen. There is not fault generated in the above situation but, when it has a long uphill, the transmission seems lazy to click down the shift. Sometimes even when I change to manual shift mode, it does change gear when to shift down. My question: I want to buy rebuilt Valve Body and all the necessary sleeve and seals to replace. Would it solve my problem? Is there anyway to determine if other part of the transmission is still healthy? Thanks you so much hey how did you make sure your bmw 550 had the 6HP26 transmission? Where can i check i am having similar problems with my transmission and i need a rebuilt valve body but have no idea where to get one. Thank you!! |

I had the same symptoms in my 545. In my case the problem was cause by worn-out seals in the tranny. I did a full overhaul of the tranny and replace the valve body with a rebuild unit.

You can send your original off to get it rebuilt. That way you don't have to pair it back up

I thought so as well, at first. However this is a 2004 model, and the transmission that's currently in it is a 6HP26. So I went with what was there.
