This is psrt 2 of the 2007 530I, last week was the teardown and now i overhaul the valvebody, installing new solenoids, new dampers(original ones all were flat) new plate and a Transgo Gen one shift kit. Thanks for watching.
Hi Gary, amazing videos. I have a BMW X5 3.0, which I just purchased. Upon checking, the tranny should be a 6hp19, however I found that the trans has been replaced with a 6hp21. The vehicle had water in the trans which I have fixed, however now it won’t shift into 3rd. Just wondering if the 21 should have been installed? Second, would the valve body be the main culprit here. Slight delay when engaging gears. Thanks Peter
Hi Gary, I'm from Northern Ireland and I'm looking to overhaul my 6HP28 Valve body, the solenoids are easily sourced from ZF, can you direct me to a service kit please. Is there any way of knowing what separator plate I need without dropping the trans pan?
Hi Gary great video mate👍🏻, I have a 2006 range rover sport v6 3.0 diesel and the reverse gear is not engaging, haven't got any codes apart from the usual lost commuinication with tcm which has been there for years now but the car was reversing. I bought a new sump pan the plastic one with filter replace the oil problem still not solved. I have just taken out the valve body open it and notice a black thick sludge on the plate in the middle, I have cleaned that plate since its not available my end. I have tested the solenoids and they all reading around 6.7 ohms apart from the single black one that is reading around 10.7 ohms. Would be grateful for further advice with this my project. Thank you and God bless for sharing your knowledge with us.
I’m rebuilding a 6hp21 with a Sonnax kit right now and when I put the o-ring on the bore plugs they’re too big (both the large and small bore plugs). The bore plug fits perfectly without the o-ring. Have you encountered this?
Great info as always. When faced with the p0706 range sensor error in these, what is the best way to diagnose the fault? Considering the range sensor is integrated to the mechatronics unit, its not as simple as replacing a switch.
@@GaryFerraro will try vcds measuring blocks and see if I can find the readout. The one other fault code that appears p1755 - 'tiptronic down switch (f189) open or short to plus. I've replaced the shift assembly in case the hall sensor magnet was faulty but it didn't make a difference.
Thank you so much for the detailed assembly. I'm looking to drain my transmission fluid on my 2007 bmw x5, but now i feel i should do preventive maintenance and do everything you just did. Where did you the the valve body separator plate from ? Did the valve kit come from Sonnax? Thank you again
The kit is a Transgo shift kit as long as you have a Gen 1 unit, the kit will work, does not work on Gen 2 units. I got my parts from Transtar. Where are you located?
Hi Gary! I know this video is about a year old but I was wondering if this kit would work on a 2010 BMW 135i. My friend has one and it won’t go into reverse after trying to fix another problem. Do you think this kit would fix that? If so where could one acquire this kit
@@GaryFerraro it was slipping from 1st to 2nd and throwing a clutch a,b, and c code and now it’s just throwing a clutch b code whenever you put it in reverse. We fixed the slipping problem though.
@@GaryFerraro we replaced the bridge seal and that fixed the a and c clutch codes but now every time you put it in reverse it goes straight to neutral and throws the clutch b code
I have a 2005 BMW 530i Automatic and car drives normal just clunky shifts but from 3-4 and up it slips then I get code 4F85 Clutch E ratio Monitoring come up and I just changed the fluid and it did nothing what would you suggest is wrong it only slips sometimes.it’s. GA6HP19Z transmission
Hey Gary, how long do you think the discs in a ga6l45r can last with proper maintenance? I have no problem working on the valve body but fear those discs going bad someday.
Currently at 180k. I'd like to get to 300. Have a slight jerk from 1st to second. Thinking solenoid. I have seen your video on the manual valve. You are a master.
Hey Gary! Nice videos. I have a U140 with 216k miles. I just changed the fluid and filter. There were fine shavings covering the magnets but no chunks. After adding the new type T-IV fluid it started slipping. I tried putting the old fluid back and even Lucas slip stop but still driving the same. Is there anything I can do or am I going to be taking it apart?
@@GaryFerraro thanks for the reply. Yes I just bought the thing. It seems to hesitate into second the worst. I used the aisin type IV like it says on the dipstick. Luckily I didn’t pay much for it. The engine runs great though.
Hey there! Is this very similar or identical to the ZF6HP26?? I’m really wanting to do a complete overhaul myself rather than having a shop do it. I’ve got a lift and everything in my garage I’ve just never rebuilt an auto trans before
@@GaryFerraro Do you have any idea where I could get a digital manual from? That would be a great help. I’ve rebuilt many engines before so I’m confident but any info I can get I will take. My only real concern is replacing the bushings cuz apparently they can be difficult
Yes, the bushings really need to be pressed in. There is a company called ATSG( Automatic Transmission Service Group), Try there website they may have something.@@tylerroe5175
@@GaryFerraro I have a 25 ton press. What bushing install tools do you recommend? Sorry for all the questions you have the most comprehensive videos on these it seems like
I have a bushing driver set, The B Clutch drum, the one bushing (on the clutch plate side is very difficult to install, i use another bushing to press that one in. The Important bushing is the rear stator bushing, i know builders who just change that one@@tylerroe5175
