ZF8HP70 Teardown
In this video, i teardown this 8 speed unit that had no forward, found the C and E clutch burned up. Parts a little rough to get, sent converter out for overhaul and worked real nice on the Road Test. Happy Holidays to all, thanks for the continued support.

I used your videos to rebuild my X5 transmission.
As always , amazing Garry. Thanks for teaching.
Thanks for these videos, they're really helpful. I'd love if you gave a rebuild/reassembly video for this same transmission. *LIKED*

Pretty tricky one there
One acre of parts for a f. gearbox.
A Nag1 to 8 speed swap would be nice!!!
nice
Longest pan I've ever seen.
No matter how many times we change the atf fluid.If there's wear on the internal components of the automatic transmission,changing the atf fluid will not resolve it and the car may not even drive anymore.Do you agree?

I guess that depends on what’s worn and how bad. If you have no more friction material left then when you flush it you won’t have the gritty fluid to help and it could make it worse. You should change the fluid before you have problems. But changing fluid can resolve issues, I had a transfer case in a f25 bmw x3 that would shutter when turning and doing a fluid swap fixed the issue.

what time in the video am i using it?
You probably seen both the 8hp70 and 8hp75 for the V8 Ram 1500, do the housings have the same dimensions and mounting patterns ? I want to swap my 70 for a 75 and use the 8hp70's electronics so everything is plug n play.
Hello Gary, thanks for this very interesting video. Nice to see how skillfully you work with these complex gears. I also have a ZF automatic, I think the 45 (BMW F36) I also have a problem with my zf automatic transmission. As I roll the car towards the stoplight, I hear a grinding noise until I come to a stop. When I let the car roll towards a traffic light and I hear the noise and put it in neutral, the noise is gone. So it must be gearbox i think. It still shifts well, a little harsh at times, but they all have that in the long run. What do you think, when you read my story? regards.

In the original bmw workplace manual for 8hp45/70 they diddnt say to replace the bolts only the sealant ring arount them how do u feel to use them again? I work on the same transmission for a project. And indeed some parts are difficult to find. Thanx in advance ur videos help me alot

Question for anybody knowledgeable here....sometimes my 8HP95 will shift from 2 to 1 while creeping forward after coming to a stop. The engagement from 2 to 1 is a very hard engagement. Speedometer reads around 1-2 mph when then happens. Is this normal?

probably but also could be just that the clutch pressure adaptives are maxed and cant command more pressure a quick transmission readout software wise could help if the clutch fails the trans will throw a code since its super smart and knows if something is wrong

Gary, quite recently we brought my 2016 1500 ram, with this transmission, into the shop because of a card in bike stokes sound when I hit the 30-40 mph range. It would go away upon manually shifting or putting it into neutral. To me, everything pointed to the MDS, even found a video that sounded exactly like the problem I had and it was the MDS.. So, they brought it in and said no, its the transmission pump.. its chain driven and when we put it up on the lift we can feel the pump shaking. But watching this video leads me to believe how could they feel the pump shaking especially where the transmission is on the dodges... they said when on the lift they replicated the speed and could see it shaking, could feel it shaking... nevertheless they diagnosed the problem as being the oil pump is shot. Is there any way that the chain can slack and cause a card in bike stokes kind of noise??

If it were pump you would hear it all the time, the pump is always turning. So you hear a noise in drive and reverse and goes away in park and neutral?
