BMW 545i E60 ZF6HP26 Transmission Seals and Solenoids Replacement

In todays video we will continue rebuilding the salvaged 2004 BMW 545i E60 by replacing a few seals and all of the solenoids in the ZF6HP26 transmission to fix a transmission fluid leak and a hard downshift. We'll also replace a coolant passage seal on the back of the engine to fix a coolant leak and, while we're in there, we will replace the rear main seal as preventative maintenance. Thanks for watching!!

You can tell that modern cars are not built to last. Look at that tranny! You have like 10 different fail points in that unit alone! All flimsy plastic and rubber and the amount of work you have to put into it to service it is insane, and that's why it's pretty expensive to take your car to a dealer or a mechanic if you don't have the tools to do it yourself or you don't know how to do it.
Many modern cars end up in junkyards due to things that are "cheap" to fix, but pretty time consuming or expensive if you don't know how to do it yourself.

Are you sure about putting oil and atf on the sealing surfaces of seals, usually these new seals are teflon and are not supposed to be oiled up because that can cause leaks?

[@rebuildrevival]

Hey, I think you’re right that BMW does say to put them on dry. I have always lubed them up some so it’s a habit. It hasn’t leaked since reinstalling and driving for about 75 miles so I think it’s good to go!

[@CrazyCroatianhacker]

@@rebuildrevival if it starts to leak again you know why :D , i know when i install them they come with special warning sticker do not oil before install but ok

[@gandalf3924]

Hello! Could I ask where did you order solenoid kit?

[@rebuildrevival]

Hey, I got them from FCP Euro.

[@hanynowsky]

Any improvement after this repair?
What were the symptoms?

[@rebuildrevival]

Hey, I was having a hard downshift from 2-1. After everything I did, the problem went away but I’m unsure of which repair I did fixed the issue. Could have been as simple as a programming issue or a combination of the seals, solenoids and the programming.

@@rebuildrevival thanks

Great video

[@rebuildrevival]

Thanks!

[@YASKY3035]

Good job, thanks for sharing. I was wondering what did you pay for the car.?

[@rebuildrevival]

Thank you, it was about $1000 including all of the fees.

[@radovanrakovicky2655]

​​@@rebuildrevival - Waaau! Here in Slovakia (somewhere in the middle of Europe) we will pay 20K for used BMW, even in that state you got it originally. Amazing prices for used cars in US ;-)

[@rebuildrevival]

@@radovanrakovicky2655 Really?! Wow

[@radovanrakovicky2655]

@@rebuildrevival Sorry, correction - I checked exact model, year, mileage...and it's 8000 Euro, not 20.000 as I mentioned before. Anyway...1000 USD VS 8000 Euro.. :-) I'm watching a lot of US/UK car rebuilds (maily from auctions, Copart) and I'm always surprised how cheap you in US can get it! Amazing work on your car, appreciate your sense for details ;-)
