Good advice here because its only a $300-400 fix and if you buy one that hasn't leaked yet, it will leak sooner than later and then you didn't even get any money off of the price of the car.

man, its common. its not expensive unless the case is cracked, and if it was, it have fluid all over the place. MQQn is correct, there is no O ring. (i just did mine 2 weeks ago) my stocker actually had to sealant at all. I used super high temp RTV between my new 4.10s and tranny with my DTE brace.
if its on the halfshafts the job just got 100X easier. you can have one of those seals replaced in 20 minutes. if its leaking between the diff and tranny, its more work, but if you do it yourself, its free...just 5 bucks for a good silicone

Alot of good advice here. I plan on looking for another one unless he gets the issues fixed. I liked the car a lot and it looks real good but I dont want to get stuck in a nightmare. I have 24k to 25k to spend and I want a Z06. This was was nice because it was local and I thought the mileage was good (42k). I didnt want to travel across the US to find one.

Hi Mike -
I think I have found a partial answer -
http://www.allworldautomotive.com/au...ts8005-33.html
This part number is only for 97-99 - so yours might have these and the later carriers did not?
I can tell you positively that the later carriers do not use an o-ring on the mating surface between the trans and the carrier. Reference the picture I posted above - did the business end of your carrier look like the above?
best regards -

The parts manual I have only goes up to 2002, and that part number is good for 97-02 with a manual tranny. The o-ring is on the tranny side, not the differential. If you took a pic of the tranny side, you would see it. I'm thinking no one ever pays attention to it. I had to order it when I replaced installed my new RPM diff.
You could be right there - I will look at my pictures tonight - I took tons of pics but they are all on my personal laptop....I am supposed to be working lol...
At any rate - for RRR's purpose, this would be just as easy either way - o-ring or no o-ring - the R&R would essentially be the same.
Lucky's point about a broken carrier or trans is a valid one - since the car has had a forced induction system on it....

Thanks for all the help on this matter, Rick http://www.rrr-racing.com/index.htm

Thanks vettenuts and lucky -
So - Ryan - you did not notice the o-ring on that, where did you read that we you needed to use the sealant? I thought it was in my manual....
I don;t think that would HURT - unless that silicone got into the diff case, it might cause problems - I would not want that in my diff.....
Thanks for the info and correction guys - I appreciate it.

I can't help but wonder how many guys don't even know that gasket exists, and just RTV the SH$# out of the surface.....

So has anyone found out where this mysterious service manual instruction is to seal this surface? There is no sealant used on this surface, nor is there intended to be. I also check the TSB's, and nothing regarding this surface. There is a TSB for using sealant on the side covers, and for the transmission/ transmission extension interface, but nothing for the transmission extension/ differential carrier interface.

No - there is no mystery - I was wrong and the manual does not say this, and there is a o-ring as you originally asserted, but it is on the boss of the rear of the transmission, and not on the differential (not that you ever said so - that is what I was thinking I would see....)
The o-ring seals against the inside surface of the carrier, and can be easily replaced.
Ryan used silicone on his, but that will not hurt a thing.
And, here is a picture of Ryans trans that I took while it was out and lying on my garage floor - you can see his has an o-ring just like you and vettenuts said.
Thanks again to you and vettenuts for the information - I am always willing to learn more and that is why I am willing to question things when I am not sure, or when I think something else is true.

Hi lucky -
So - looking at this junction of the diff to the trans, it seems that the diff fluid could get into that area through the opening to the side of the hole that the transmission output shaft inserts into.
I wonder if there should be gear oil in that cavity?
Also, if one saw trans fluid leaking out of there, that would indicate a rear seal on the transmission was bad, as well as the o-ring around this junction.

Thanks again. I bought it. I got another $500 off for the leak. He also gave me three large manuals for the 01 Z06. It has step by step instructions for the diff removal. I'm sure I can get it out and back in.

Here is where I read this - it is not in the manual, it is in a TSB as you indicated - here is a link -

"Engineering has recommended the use of a sealant..."
The above is for the side cover, and not the diff to trans junction.

Not to hijack this thread but thought I might ask if there are any "might as well" parts to replace or upgrade when replacing that trans o-ring? I just picked up a 00 FRC and its leaking there.
Also can the rear trans seal be replaced from that end?
