Wynn's Transmission Stop Leak

[Patman]

I know you guys will probably call me crazy, but I just added a bottle of this stuff to my Firebird's 4L60E trans today! I've noticed a minor leak and figured I'd give this product a try to see if it worked.

Here is what it said on the bottle:



Automatic Transmission
Treatment

Smoothes and quietens gear changes and powersteering operation cleans and protects the auto transmission and powersteering system
Prevents oxidation and aging of the transmission fluid
Rejuvenates rubber seals and O-rings, stopping and preventing leaks


We'll see if it works! If my tranny dies, I'll use it as an excuse to my wife to let me get rid of the car and buy a 97 Corvette.

Don't ever use any Wynn's products and run away from the mechanics that use it. This is the classic case of snake oil. Most of these additives do damage rather than improving something. Why didn't your just use ARX or AT flush with Lubegard?

I just used Wynns tranny, P/S, and coolent flush. Wynns is GM approved and many dealers use it. I have read a few articals in various car magazines that had good reviews of it.

Why do you think it is bad? Any proof of info to read up on?

We had a 1989 Jimmy with almost 200,000 miles and had Wynns done to it many times and the truck had no problems ever when we sold it.

Even though I've got some Auto-rx at home (2 1/2 bottles actually) I didn't want to use it since you need to do a trans flush after putting it in, and I just spent $100 on a trans flush a few months ago so I didn't want to spend another $100 if I didn't have to.

I have a 3.3l Dodge Caravan that used to burn a quart of oil every 600 miles. I started adding Wynn's Engine Stop Leak(labeled for oil leaks and oil consumption) with each oil change and now it burn a quart every 6000 miles!!! I generally don't believe in aftermarket additives but this one seemed to work for me.

Perhaps you'd be kind enough to direct me to the section in G.M. owner's manuals where I can read about the G.M. approval of Wynn's transmission products. I can't seem to find mention of this in my better half's 2000 Chevy Cavalier manual. Thanks.

Ray H., Your precious owners manual that is cut a pasted together by girls with zero automotive knoldge makeing $minium wage is practicly worthless. The owners manula is their to give basic information to people that know nothing about cars! It is not an all inclusive guide. Even Servie Manuals are static and and of limited specific information. Car companys spend millions getting current up to date information out to their dealer network. THings change freq. and quickly. OEM's are not going to tell you wich products they have approved for use by the dealer network. They also will not tell you what companys products they are haveing re-labled for their use in most cases!

Ray, The 3 dealers near where I live and a local quick lube all advertise Winns and GM's approval of it's use on GM cars and trucks. I have a Winns pamplet and it even says GM approved. My owners manuel does not mention anything about Wynns.

I think that one of the reasons dealers use additives is to give customers some confidence that their car would run better and more reliable. They also charge for the additives and service about 200% the price. Dealer in my area uses Granitize brand for ATF/PS flushes and additives. They also use some kind of Graphite additive into engine oil (for $5 extra). I very doubt it helps anything. I've never seen a dealer using additives of respectable company like LubeGard. LubeGard is the only company I've seen which provides test results from accredited testing lab. It is probably the only real company on the market which has been directly officially approved by some (not all) manufacturers to be used in their cars. Surely even LubeGard amplify some claims, but still...

Automotive additives market is very profitable. However, why do you think that large companies like Mobil, Chevron, or Castrol don't manufacture any additives? I suspect that most of the additives on the market simply don't work (some even harm operation).

By my own stupidity I've tried a whole bunch of additives. Now I don't use any for the exception of major brand fuel cleaners (I prefer Redline SI-1). I personally trust only LubeGard. Thought I would not blindly use every their product. So far I've been using only LubeGard Red. Other products I believe are not really necessary. ATF and PS cleaners might be a good thing but you need flushing equipment to take full advantage of them.

I said it before and I'll say it again. Good oil, even mineral one, and reasonable drain/maintenance interval is all you need to keep any part working properly. If part starts to fail not a single additive will be able to fix mechanical problem. If you think that some part fails sooner than expected even with good maintenance - that's not your fault, this is a design or manufacturing flaw. This does not apply of course you abused the car by using it in racing or heavy off roading. In that case most complains toward bad design/manufacture are void.

Regards,

if autorx is supposed to do half the stuff everyone claims it does, why is your tranny leaking after you did a treatment with it?

I've never done an Auto-rx treatment in my transmission though, only in my engine.

I am not saying that additives are the answere to every vechiles problems. Sometimes they are used to maska poor design through it's warranty period. SOmetimes their is a legitamate use for them. Sometimes it is a money maker for the service department and nothing more. Only in rare cases do OEM's make known to the public wich additives they endorse. GM has a chemical catalog for it's dealers. GM goes to great lengths to keep even the dealers from knowing who is makeing the product for them.

I have gone to great lengths to find out who is makeing some of my favorite GM products for my own coonsuption and curiosity.

You should never treat an owners manual as anything more then a very basic guid to your car!

I used Wynns Trans stop leak for a minor leak in my Dodge 3spd auto trans, 4 days later the tranny wouldn't upshift anymore!!! Now I think I have other problems!
