OK. I'll play.

Thanks for responding. My question was asked as such to inquire of those that may have purchased a "transmission seal kit" that includes the above mentioned seals, (apparently an exterior seal kit). I thought this kit would be kind of like an engine seal kit that would provide all the seals needed to seal the transmission. This kit seems to provide a minimal amount of seals, and no seal that would be responsible for the tranny/diff fluid exchange problem.

A person having purchased said kit or replaced the problematic seal(s) may know what I am talking about and offer an opinion about their experience. Maybe not.

It seemed odd to me that a "transmission seal kit" would include only exterior type seals (ie the seals that only require removal of covers (governer and 2nd gear plunger) and some external components (2nd gear plunger, governer, pan) as well the gasket and o-ring for the seperation of the tranny and diff (though not the main shaft seal twixt the two), and not the apparent plethora of seals inside the transmission and differential. Changing these exterior seals may be helpful, or may just be potentially opening another can of worms if one is not prepared to handle the entire rebuild (something I was hoping to avoid). Some of the seals in the transmission and differential require entire dissassembly of the tranny and diff to replace. These seals are not in the kit I have. As well, the friction pads and steel plates are not included which I expected as I wasn't planning on rebuilding, just sealing. I was surprized that the seal kit seemed so light on seals and didn't seem to have the seal(s) for the fluid exchange.

I was hoping that someone would know which particular seal, if it is in fact one, that causes the leakage from the transmission to the differential. This way I would not necessarily have to dissassemble to explore for hard, cracked seals (that likely should be replaced after opening a 20 year old piece of machinery anyway).

That's what I thought would be recommended.

So, since it appears that I will be dissassembling the tranny and differential to change all the seals (that may come in a "master transmission rebuild kit" or may not.)

I am pondering if I should then consider reinstalling the transmission that I thought was dying (that actually may have been the worn cam lobe making the engine operate on only two cylinders and not have been transmission issues at all...), while I source parts and learn how to rebuild a transmission. I may find that the old transmission is fine and will carry me through this camping season while I work on the new transmission. If not, I'll park it and do the rebuild right away. Then when the tranny is rebuilt, swap it out.

Removal of the tranny with the engine in does not appear to be too difficult, so a future swap may not be too bad.

Or just consider that this next camping season may be out while I do a complete transmisison rebuild. I am of the 'If it aint broke, don't fixit" mindset. Cursery inspection of the 'New Tranny', does not indicate leakage or fluid contamination in the diff.
I am concerned that I can get started on rebuilding the transmission and hit a dead-end with part sourcing.

Chilly up where you are?

Gypsie, you know that these kits like to miss. Why do engine seal kits decide not to supply the front main seal?
Why does packaging at FLAPS give you three in a package when you need four?

If we look at the layers of thoroughness in transmission seal kits, you would expect that there would be some sort of common sense and successive layers of depth, but I cannot glean the logic of what looks like haphazard assortments.

In your specific case here, I have no VW automatic transmission experience to share with you. When bush-whacking through the thicket of decisions, I can only say that I have let some things go for impossibly long times because they "look all right to me", and they just kept going. I never did touch the left rear wheel bearings on the Road Warrior, and that included the seals too.

Hey maybe check with a VW dealer, I wonder if they still stock some of those parts. Go Westy may be a good option too. Bus boys? I dunno but have a Vanagoon on the cover.
You will not miss another :argue: camp season.

No, he shaln't.
I need to do at least one with you guys. This is embarrassing, you'd think I was anti-social or something.

So here's what I found out about "THE SEAL"....

it is actually 2 seals, sometimes called back to back seals, or 'differential seals, though the last one may be misleading to a parts house.

They are twixt the diff and tranny housings around the shaft...

If one wants to replace them one has to pull apart these two housings and separate the two sides. One may need to change, perhaps should change, the gaskets and O-ring twixt the housings in case they tear or get damaged during this procedure.

I think I will attempt a clean install of the "new" tranny as is. if all is well and it works, my original stock tranny will become my 'guinea pig'...er...uh...'trailblazer' rebuild tranny and I will be set for the camping season. Ifn' it doesn't work I will swap out the 'new' one for the original in hopes that the perceived issue was in the cam not the tranny.

I have prepared the mount forthe new cooler, wired it with an adjustable thermoswitch, assembled the necessary fittings and tranny fluid lines to install when the weather allows it. Great to have a garage but my van won't fit in it and the street is a lot less friendly than my old place (uneven, muddy, gravel, and downright icky...) till the sun shines. Then 'taint so bad.

I have been working on electrical stuff (engine bay starter button for easy starter bumping and such...) Running wire for the new guages I will be installing (oil pressure, oil temp, and a 2nd head temp) for a final tally of 6 guages (volt and tach), have dash pods on the way for the guages.
Also futzing with some interior body stuff (floor panels under the feet need por15 treatment)and the mold that started to grow on everything in the bus since it has sat with no heat in it since...uh....last summer. Here in the NW cold and wet is our middle name...

Hard to work in the cold and dark after getting home after work and free weekends are few.... but steady plodding forward. I need to get this cloud of 'unfinished' from over my head as it is debilitating.

I see camping in my future....ohhhhhm......
So it all started when I wanted to get better gas mileage....

Give me a holler if you need help. What about taking a weekday off?
