- In this video, i teardown a ZF5HP19 out of a Porsche Boxster. This had the very common problem of the pump bushing spinning out and leaking from the front area of the transmission. This transmission is front wheel drive. Thanks for watching
Thank you Gary,
This has to be the best transmission teardown of the year. What an interesting way to integrate the differential.
Merry Christmas to you and your family.
Thank you
subaru's are kinda similar to this too.. and they even use a similar boxer engine as Porsche.
Nicely done, Awesome.
Boa tarde Gary só pra desejar um feliz natal e feliz ano novo pra vc e sua família muito bom o vídeo meus parabéns
Another great video, I am sure you said in the video but i missed why the pump had to be replaced. I didn't know if the bushing on the pump could be replaced.
Bushing spins out, i always go with a new OE pump
thanks Gary 👍👍👍👍👍👍
gary the awd hp19s are actually zfhp19fla
This one is not AWD but you are correct
Hi Gary, thanks for this video. i have to rebuild a 5hp19fla (audi) and there is no shops that do that transmission here where i live so i will do it myself (it will be my first auto rebuild). i just order all the overhaul kit, pump, valvebody overhaul kit too. But I would like to describe the symptoms to know if it is possible for you to guide me to what I need to pay attention to the most.when i bought the car, the change between gears were a little abrupt when cold and much more abrupt when hot. On a very hot day, after stopping for a few minutes, when leaving it was slipping in all the gears(this only happend once). So i drop the pan, change the oil and filter (there was a LOT of residue on magnets) and fit a transgo presure kit, after that all got worst, start getting the TQ converter lockup stuck off (i haven any codes before) and after a heavy throttle or long trips i have all gear slipping (even the car try to move but with no sucess) or hesistate when i try to start from a stop, like nothing,, a little bang or delay and then start to move..(when is no full slipping but is hot) and a big BANG dowshifting from 5 to 4 or 3rd (Always). when the trans is slipping i dont get any code (more than the TQ converter stuck off) but not limp or gear monitor.
Sorry for the long text and my english but any advice would be very useful.
Thank you very much!!
Where are you locate? Was the car scanned for codes?
@@GaryFerraro hi Gary, i live in Argentina. I have the scaner (vagcom). No codes.. only the torque converter lockup stuck off (after the service and tranago pressure regulator kit)
@@GaryFerraro any help will be very helpful. Thanks
is the trans apart, how is the pump and the pump bushing. you said you changed the filter, how long after you changed the filter did the car stop moving hot, your almost describing a clogged filter, possibly from the converter coming apart@@bymiki
@@GaryFerraro Hi Gary, i didnt take the trans apart yet, i was waiting to get all the parts for the rebuild (is my daily). so i dont know how the pump is, but I order a new one. and how long after you changed the filter did the car stop moving hot.. like the first full throttle after warm up. i changed the fluid between the next 3 days, The oil was clean but very liquefied (or liquid, like water). I think it was a fake fluid (motul). with the new oil, it improve a bit, but after a heavy throttle, or like winding or mountainous roads, the things get bad really fast. Can a poor quality filter cause problems? thanks for your time!
on automatic's especially vw audi
etc
This was a really great video! @GaryFerraro, what parts of the 5HP19 tend to be the limiter on the amount of torque that they can handle? In other words, can they be built to handle quite a bit higher than factory power levels?
Great video how do you remove these cooling lines from the transmission ?
should be held on with brackets, i remove them and the lines should come right out
I just finished a rebuild on a GMR 5hp19fl. I got the transmission installed but it doesn't engage any gears. It goes into gear it just doesn't lockup the clutches properly. I air checked all the clutches before I installed the valve body and they engaged firmly. I double checked that the shift linkage and selector were synchronize and they are. My suspicion is when I had the unit out I tried to remove the flow control valve but wasn't successful and I think I may have damaged it. I'm worried I may have to pull the unit out again and replace that flow control valve. When looking through the spare parts catalog I dont see that valve as a replacement part and think I may have to replace the whole intermediate plate and that would come with a new valve installed but I'm uncertain.
I'm not sure what to do.
Are you sure the converter went in all the way, maybe you broke the tabs off the pump
@@GaryFerraro The transmission attached to the engine smoothly and bolting up the flex plate to the converter was smooth too. If the converter wasn't set all the way into the pump I think it would have been difficult to get the transmission to mate to the flex plate. Im sure it was installed properly. The converter is a reman Recon from TransStar.
If I put the shifter in a gear it will turn the wheels if I apply a little throttle. I'm going to make sure the valve body pressure regulator is ok and if that checks out I will have to pull the trans back out again and check that stator pump piston. Correct me if I'm wrong but I think I found the part number for that piston 1060310079 but I'm still not sure how to remove it. Should it just slide out? Do you know if I can buy the stator piston only or do I have to buy the whole intermediate plate?
Hi Gary thanks for sharing, this seems so different from other zf rear wheel drive transmissions
Have a merry Christmas and wish the new year brings you lots of happiness and prosperity.
Thank you, you too. This is different from your average zf5hp19
the is an fla just no torsion diff
Good morning what’s up man everything OK 5Hp19 the common problem pump bushing ripped apart. I get those transmission in my shop every other day
everything good here, i get a lot of these too
I did a rebuild of a 5HP19 for an E46 BMW (seals, friction discs, steels), and installed it. I am getting bubbles in the fluid. Also only transmits limited power to rear wheels if I apply throttle and nothing in reverse. When I remove the lines from the transmission cooler there is no flow with the engine on. Any ideas where to start for diagnosis?
Are the 2 plastic tubes installed between the valvebody and pump?
Thank you it was great.i whish you would show how to assemble transmissions.
Excellent teardown video of a old tried and tested transmission by an unassuming and knowledgeable expert. Looking forward to the valve body video. Please if you could describe how the valve body actually works. After taking apart mine I realised that the design is an engineering marvel.
Now to my issue on an A4 B5 2.8. On hard acceleration, the transmission does not go into limp mode but instead im no longer able to downshift on its own from 5th to 4th. I have to shift manually. Also slams into reverse. Did all the resistance test a on the different components and found the OSS resistance to be at 890 ohms instead of the 325 spec. Bought a new One, and still get same reading. Watched your video on the F clutch drum issue. Could it be this? Please advise.
@Nagato is better than Punk Naruto p0734. I'm thinking it's the gears or clutches...
I have the same transmission that’s leaking from the front, but the converter isn’t stuck on the shaft and the bushing isn’t welded to the shaft. How do I know if the converter is bad?
It would have to be sent out and leak checked, make sure the bushing is not loose in the pump body
I’m replacing the pump body. I’m in Michigan, where is a good place to have the converter tested?
What fluid do you recommend when putting back together?
@@GaryFerraro I replaced the pump and still have fluid leaking. Any idea of next steps?
Gary I have a 2001 986 boxster with the same issue can u do the rebuild and get parts?
yes i can, where are you located?
Muito bom o vídeo. Me ajudou bastante. Muito obrigado
Nice vedio ❤
I have a 98 Boxster with a continuous leak from the front. Assuming the same prob. If I keep the tranny filled, can I continue to drive? What are the symptoms?
chances are your pump bushing spun, that would leak to fast, i would not drive the car
This is why I will always own manuals.
Shut up
@@hondaveetc82 lol.. What if I don't.. What's the matter, You still can't work a clutch can you. bwhahah.. rookie
Can you do video on tranny that claim uses lifetime fluid?
Gary, great video and content! I'm wondering if you could show also how to put back together both the transmission and also the differential.
The transmission has been shipped back to the shop for install
what is the oil pump I need for the boxster trans & where can I get one ? Is the bww vw pump the same?
you have to look at the casting number on the pump, numbers are on the front and see what the last 3 are
Hi Gary. Great videos . I have a 911 with a zf5hp19 that has lost drive in reverse and a noise in all forward gears . Any idea what this could be ? Keep up the great videos .
is the noise a whining noise?
@@GaryFerraro hi . There was a slight whirring noise which I suspected as a torque converter but a crunching noise in forward drive without movement . There is no noise in reverse . Again no drive in reverse . Thanks
@@sheldoncorr3476 How did you ever come out with this? It sounds like your D-G clutch drum broke (on the D side), leaving you with no reverse. There is an updated drum for this. I'm guessing you probably found this out. I wonder if the whirring and crunching sounds were the pump bushing starting to bind on the converter?
Er, Gary, these things are rear wheel drive, not front wheel drive as mentioned and noted.
you mean the trans is in the rear of the car?
@@GaryFerraro I expect so as the driveshafts drive the rear wheels. Engine also resided in the rear if my technical information and memory serve. I cannot remember any front wheel drive posches, 4 wheel drive yes, rear wheel drive most certainly. In fact there were only a few models built with an engine in the front, albeit they drove the rear wheels too. The 1998 boxter is rear engine rear drive.
Engine and gearbox is in the rear in a Boxster. It's not a front wheel drive...
Some Porsche's (924, 944, 968 and 928) had the water-cooled engine in the front but even here the gearbox was at the rear (Transaxles).
Hi everyone I think what Gary meant its a transaxle
A Transaxle combines the transmission, differential, and ancillary systems around the axle into one integrated assembly. You will usually find transaxle configurations in cars where the engine is placed at the same end of the car as the drive wheels.
@@rafiekahmed8568 yes, the concept of this trans is based off front wheel drive
I just recently put my ZF5hp19 back together after a rebuild. Only to find that is has no endplay on the pump shaft. I hear this is a bad thing? I’m going to open back up, however do know how I would set the proper endplay?
did you change anything as far as hard parts?
@@GaryFerraro technically yes. I set all the parts on a table in order. I thought I put everything accurately back together, however I found a pretty thick washer left on the table. Have no idea where it goes?? Looked in many manuals, but it has not part number and many manuals don’t even list it as a part. So I think it’s some sort of spacer…so frustrating. I’m at the point where it might be better to just buy another one and rebuild?
