Wow, I'm not familiar with this stuff. Anyone else ever use it and/or have an opinion? I'd be leery about adding unknown gunk to my oil, especially stuff that glows.


nothing to it. you pour dye in oil or transfluid run engine a bit shine UV light on it Mr. Magoo & Ray Charles could see the dayglow dye (green or orange) it doesn't hurt anything.. and if your still worried about it then drain and replace oil / transmission fluid... I found leak on friend Chevy.. hairline crack in head....we welded crack up..

Hey Mighty Art...Since you have the rubber boot in its intact state...could you take a look in the misc. auto parts isle in the local flaps and see if there is some rubber piece that would sort of work in its place? We would be very grateful.

Sorry should have said seal, not shield. Adult onset dyslexia you know. Look at page 35.97, Figure 9 in the Bentley, you can see how the slinger fits behind the seal. Slinger is probably a misnomer, there is probably a more proper name for it. Unless you have had a pilot bearing failure this is not likely your problem though.

ill change that seal anyway. thanks for the tip.
I have the bentley specific to the aircooled vanagon, so mine doesn't have a 35.97 page in it, but im sure it'll make more sense once I get the input shaft seal out.

Check this thread for more on the slinger.

And while your leak chasing, you might want to read this. It applies to air-cooleds as well:

it does?

its a tiny tiny little hole, yea?

I think mine is blocked off by the gasket that mounts those two parts of the trans together.


just confirming the location of said hole:

this is how far I can go in before I hit that gasket:

see, exactly as deep as that gasket would be:

stab it through so it can vent, or is this the wrong location for this vent to be?

I don't have and air-cooled transmission to compare to. That certainly looks like the bleed hole. I have a couple thoughts. Perhaps there is a second vertical drilling that connects to that hole or perhaps you are bottoming out on a screen that is there to prevent dirt from getting into the transmission. My course of action would be to clean the hole and around the hole as well as I could, remove the fill plug and try blowing a little compressed air in there to see if I could tell if it was flowing through the bleed into the case and out the fill hole.

it's hard to say, I haven't put my trans back in just yet.
this was all checked out with the trans on my garage floor.

based on where it is, technically speaking its not completely blocked, but you'd have one hell of a time being able to see it. you will def need a mirror and a flashlight.

id try and clean up the area as much as I can, then get your digital camera in there as close as you can and see if you can get a shot of it in Macro mode. that might *might* be easier than seeing it with a mirror.

unless there is a tiny vertical tube that this little channel connects to, and I don't see one when I look inside mine, it looks like its just totally blocked off on these aircooled models.

Check the post I just added to the tanny breather thread. It shows the internals. It is NOT blocked off in the air cooleds. If you were to tip the tranny on it's nose with fluid inside, you will see the fluid come leaking out.

Yes, you can get to the hole with the tranny in the vehicle, but it is not easy. I believe you could actually put a jack under the tranny and remove the mount and entire nose cone with the tranny in situ.

ah-ha!

so it does go in just to the point where it mates with that other part of the trans, but then there is a little channel going down that makes the connection.

awesome picture.

I don't see how you can clean that out though, without removing that nose cone or whatever you call the end of the transmission.

maybe not that big of a deal to take off, I haven't looked into that part of it yet. likely will need to replace the gasket when doing so though...

I like the camera idea...I may just do that to check and see if it is dirty.

A small wire or even a squirt of WD-40 would clean it out, I just don't like the idea of sending grit into the transmission. Very easy to pull the nose. Only 8-10 m8 bolts and it pulls right off. I'd clean it first on the outside to reduce crud getting in. A very light smear of RTV (I like Permatex Ultra Grey) would do just as goof of a job sealing as the gasket. Don't put enough on that it will squeeze out when bolted together.

Do you know were the tranny was rebuilt? Are the trany numbers re stamped??
I posted the question earlier but no one knew of anyone re stamping them. The painting on your tranny caught my eye. It looks exactly like the one i have.

Were you running red line oil?


thank jcl

I don't know what kind of oil is in it. I purchased this rebuilt transmission via German Transaxle out of Bend Oregon. I had technically got it from my mechanic, but thats where they buy them from themselves.

it's painted black.

as for numbers, I don't know that anyone re-stamps them.
these are the numbers on mine:

Image may have been reduced in size. Click image to view fullscreen.

that last one is hard to read, but its 091301211A, which I believe is an original number as well.

Ill give German Transaxle a shout out . The numbers I have restamped are the tranny code on the bottom (drivers ?) side.

Hey I think this might work for the rubber boot on the transmission ..it is for Vanagons after 1983, but it looks like it may work on ours.

http://busdepot.com/details.jsp?partnumber=020301261A

What does everyone think?

That looks EXACTLY the same.

I just got my parts in finally, even though everything went back together and work just fine with all of them totally worn out (go fig)

I ordered mine from serial-combi, but for the little plastic circle gear looking thing it shows being from JustKampers. FYI

Just a suggesting to improve parts life a bit. On the socket where the shift rod and transmission meet, if you drill a small hole in the bottom of the socket then you can use a needle to grease the socket from time to time. I guess a grease fitting could also be installed, but have never tried it.

Chris, how long did it take for you to get your order from serial-kombi. I ordered some stuff from them in March and am wondering how long I should wait before I should be concerned.

Thanks
