Transmission trouble

[eacmen]

What is the proper way to install a slave cylinder on an SMG. I have ISTA+, had a look at the TIS, and It's very trivial. What makes me doubt is, there is nothing said about bleeding.

Is it better to pre-fill the slave cyl. with Pentosin, does the bleeding procedure in INPA or ISTA take care of everything?

I'm curious about the mechanical way in which air makes its way out of that cyl., since there's only one line. Anyone knows? When things don't make sense to me I get paranoid. I don't want to have to remove the slave cyl. once installed on the car! Thanks

Bleeding sleeve shouldn't be an issue. Just run the procedure.

Thanks for all the advice.

What's up with part 4 in this diagram? I don't think there was one when I removed the output flange, but TIS says to install this and RealOEM shows it grayed out. Just being on the safe side asking.

Interesting that the diagram shows part 4 aftr the big nut. If used it should be under the nut and functions as a lock. Is the nut some kind of Nylock?

No it's not a self-locking and neither TIS nor the Bentley mentions replacing the nut.

Can someone confirm the proper installation of the vibration absorber on the cross-member (my bad here, forgot to document on disassembly) ?

Does the vibration absorber stack on top of the transmission (as in the image - transmission, vibration dampener, nut) or is it the opposite (vibration dampener, transmission, nut)?

In other words, should the nut contact the vibration absorber (like in the image) or should it contact the transmission's bracket?

Looks correct in the image and the damper stacks on top. Here is a video for reference - https://www.youtube.com/watch?v=NmEOFBqreX8

No, the rubber damper should be under the tranny. There is no space to mount the rubber on top even if you try.

My wording "on top of the transmission" is confusing. I meant the transmission mounting bracket (the silver part between the rubber thing and the mounts in the photo belongs to the transmission assembly).

The question was: is it bottom-up: cross-member, mounts, tranny, vibration absorber OR cross-member, mounts, vibration absorber, tranny?

Thanks for confirming that the photo shows it properly mounted.

Everything in the pic looks like silver or gold.

I still have to idea -- the tranny mounting bracket? what bracket? Is it the cross bar, or the tranny mounting foot? You better highlight the parts with A, B, C, ....so we understand.

Ok, here is an annotated version. My question was if B goes on top of A, or vice versa. I'm calling B "silver" an "the transmission bracket" because this is what secures the transmission to the cross member assembly.



On a different topic, what amount of play is it okay to have in the differential input?
Before the clutch and flywheel job, I had some play in the driveline. It exhibited a clunk when the torque shifted (for example when shifting gears). It could be the dual mass flywheel, but the old flywheel turned out to be not as bad as I thought it would. I have not driven the car since the job (still working on some engine-bay stuff).

The question is: is the amount of play shown in the video normal (handbrake on, turning driveshaft with my hand).

B should be on top of C.
driveshaft plays: normal amount.
Clunk I think is in the diff; same noise when talking off from stop?
The clunk: clutch stack slip letting the side gears hit the spiders hard.

Personally, I've had my fair share of transmission woes in the past with different cars, so I can totally relate.

I'm curious—has anyone here had experience with the 700r4 or similar transmissions? How did it work out for you? Any tips on what to look for when considering a replacement? Your insights could really help others facing similar issues.

One thing that caught my eye recently was someone mentioning a "700r4 transmission for sale". It got me thinking about options when you're facing transmission troubles. Sometimes, finding a good replacement can be a game-changer, but it's crucial to weigh all the factors—cost, reliability, and compatibility with your vehicle.
