Been looking at this thing on and off for hours cleaning it up. Everything was wet at first. There is no doubt the seal is leaking. But is seems to be wicking around the bottom of the connector which just leaves me with some question. It's not the money, I just don’t know if I want to be sure 110% change the whole darn thing as and be done with it rather that do it twice. I hate being unsure. I'm my worst devils advocate.
I understand. For me it is the labor too. Not too hard a job, but just jacking it up to get under it and how much fluid comes out and needs added later, etc. It all takes time and motivation.
So I see a little wetness inside the connector that seems to keep reoccurring. Even though the major leak is from the "O" ring I won't be happy unless I order a new one. Don’t want to do this twice so a new one is on the way.
Thanks for looking.

Ha, over in GD I have a thread on the same leak. Also a '94.
I'm likely just going to clean up the sensor and replace the O-ring, unless I decide it does need the sensor as well. I ordered the VSS removal tool on ebay since I've heard you can end up breaking the sensor if you remove it with another (more difficult) method.

That’s some interesting thread I found also in the general area. Did not look like it would be that difficult. That’s one special tool I don’t currently have.
Would love to hear if anyone has taken the sensor out without the tool.
And most important can you get it installed back in without the tool?

I've never used the tool on a C4 but have seen it used on the earlier trucks that use the same sensor. If you're not saving the sensor there's no need, if you understand that it needs to be removed "straight out" with no twisting and turning there's maybe no need for it either. There's not a reference to it in a FSM that I've seen so by the time the VSS made it to the C4 they assumed it's maybe not required and there was sufficient experience in the field.
If you look at an image of the tool and an image of the VSS you'll understand it's purpose, a handle that allows you to pull straight out and tap the VSS back into position if you want.
If you'd like to try it I'll do the same for you as I offered the other poster, USPS both ways and hold the tool for 30 days isn't a problem. Christmas shipping I think would require Priority Mail to insure the delivery. It will easily fit a small USPS PM box or bag.
I am installing a new sensor. At the same time I don’t like mangling anything (just in case).
10-4 on the page number, been there. I did get the gist of the tool after looking at it on EBAY and internet. Thanks for the feedback.
I'll keep your offer on the side and attempt to do the job and see if I get lucky. It's leaking so bad the darn thing might fall out. Hope the part will be here at end of week. Would like to get the job done but not in crisis mode.
My 94 FSM actually does reference the removal tool twice. But since its cheap secondhand and i got free priority shipping, no biggy. Im reusing the sensor, so i dont want to jack mine up.
Since the OP is replacing his, no special tool is necessary. Not that it is in my case either, but as a precaution ill use it.
After looking at all the pictures of the tool on EBay and the internet, I just got wild hair and took a shot at building one. Had some angle iron which was a good thickness and real strong. Then with my reciprocating saw I made a rough cut using the new VSS as a guide. Then I had to shave it down so it would fit in the space provided on the transmission. I was going to fold it over as the manufactured ones looked like but at the last moment just made a handle. Tool, J-38417
I know it's crude but was not trying to win any awards.
It worked real well removing it easier than I thought. On install I put the new VSS on the tool and slid it in as far as I could get it, then removed the tool. Then when I could see made sure the bolt hole was aligned and pushed it in all the way.
So the job is completed but have not put fluid in yet cause I'm working on the pan at the same time. Hope it all is good.
Talked to a transmission guy I knew and said he doesn't have or used the tool so each to his own.
WVZR-1 - I'll pass on the offer this time but do appreciate it.

An interesting fabrication that "works" and is all that's required. Never having an A4 or using this tool on a C4 is there sufficient room to use it as intended?

Yes, it just slid up there vertically.
As it was going on, it actually released some. Then a little tug and it was out, no muss no fuss. I will say that the "O" ring was totally flat which is the reason it probably came out so easy and why it was leaking so nicely.
You probably can't see it from the picture and did not want to post another picture but the handle curves toward the center so when you pull the force is pretty much centralized rather than a edge force. It should come out easier with a symmetrical force like the production tool.
You can't make to tool to big and was concerned about the strength of the steel as I cut the tool down. But the angle iron was so strong it turned out not to be an issue
I have the same problem with my 95 C4. I disconnected the connector, cleaned up the blue gasket seal and wiped everything down. Mine is definitely leaking around the housing, along the circular seam of the casting. It only took a few minutes for it to get wet and start dripping on the exhaust there.
