Hey Gary, Just want to thank you for putting these videos out there. I'm working up steam to rebuild my zf6hp21, oil filter blockage caused some damage, I think the rollerbearing in the Oil pump assembly let go. only one way to find out!
Hi Gary, I really appreciate your videos. I’m about to overhaul a 6HP26 in Australia and was going to ask if you think Sonnax bushings are ok to use ? I can probably get the Omega machine bushings if you think they are better. Thank you
Hi Gary thanks for another couple of great and informative videos, I'm just replacing the bushings on my 6hp26X(06 E53 X5 diesel) I have removed the rear stator bushing and come to fit the new one and checked it on the drum shaft and it seems rather loose, I've checked/measured the shaft and it's not worn and no low spots. I've fitted the bush to see if once fitted it would snug up and take out some of the play but it does seem to wiggle alot to say it's also a fluid pressure seal? I know some kits have two sizes of stator bushing but the difference in sizes is significant so you can't mix them up. I've ordered a different make of bushing kit so I'll see if it's perhaps a poorly machined bushing? What kind of fit and I looking for between the bushing and drum shaft, noticeable play or a snuggish fit? Thanks again for your videos and sharing some of your vast knowledge.
@@GaryFerraro it's a set I bought from eBay which claimed to be OEM replacement, I suspect on reflection that they're possibly a Chinese copy unfortunately 🙄 I've ordered another set from a reputable transmission supply company over here in the UK which is coming in later today so I'll see how they fit, hopefully alot better as there's definitely some play there at the moment 😔 thanks for your reply and help.
Hi Gary, so I completely overhauled my Zf6hp 26 auto with new Torque converter, new bushings, new friction plates, new solinoids, rebuilt the valve body with Sonax kit and reset all the adaptions etc..... I'm still getting the 1-2 gear clunk and 2 down to 1st gear Ahhhhhhhhhhhhhh any ideas sir? Thank you
Before you do anything reset adapts again but make sure no codes are present in trans ad engine or adapts may not wor. Also, these transmissions adapt when trans temp is 130F or above
Hello Gary, Firstly thanks for your information and we'll explained vidios. I have a question on the bushing replacement. The rear output drum and speed sensors pack had a bushing which is 'Staked' in position. Can you advise on the best method of replacement for a back street machanic please. Best Regards Martyn
Hi Gary, thank you for the videos. They are a great help. I am in the process of rebuilding a 6HP28 unit. I wanted to ask your opinion on what to do with torque converter and friction discs. My transmission was losing 2 liters of fluid every 8 months or so. The TC seemed fine, no noises. Is it absolutely necessary to have the TC rebuilt? Also is it a good idea to replace all friction discs while it all apart?
@@GaryFerraro Thanks for replying. Either input shaft seal or the large O-ring around the pump. It appeared to only leak while driving because there was never any transmission fluid where the car was parked. So you are saying to do the TC and the frictions or just the TC. I haven’t dug into the clutch packs yet but A and E don’t have any discoloration on the drums.
Hi Gary, my zf6hp26 after driving for long ride then coming to a stop. I get a slight bump motion (jerk action), I suspect is the bushings. How long do I have before the problem gets worse ? Trying to financially prepare. Thanks for your advice and videos.)
Hello Gary. at 6:42 the smaller drum spins freely. In my installation its very stiff. Does it have to be that free or will it correct it self when driven?
It should spin free, if tight, there is a chance the bushing will come out of place, try to lighty tap on the smaller drum to try to seat it in place. ary
Gary Ferraro Thanks Gary. And yes, I noticed it’s still fully bronze coated and looks as good as my new ones, so I was leaning towards just leaving it.
@@mrgabriale There is a company in Europe called Automatic Choice, I am in Talks with them for some 8 speed ZF parts WWW.Automaticchoice.com i believe is the website, check them out
Hello Gary. The last bushing you showed did they have lube holes in them? Coz I see Lube holes in a bushing where the planetary system is, and I cant not see how to install or remove since they have three notches on top. Your help woulb be greatly appreciated.
