Guest shadetree77 Posted August 13, 2012 Share Posted August 13, 2012 It was suggested to me to add some STP to my transmission to slow a leak. I bought the bottles pictured. One is the standard oil treatment, the other is a high mileage version. Neither one says anything about transmissions though. Did I buy the right stuff? Which one should I use?

D Yaros Posted August 13, 2012 Share Posted August 13, 2012 If you use any, use the blue bottle. Have to say, it is not going to stop/slow your tranny leak. Link to comment Share on other sites More sharing options...
old-tank Posted August 13, 2012 Share Posted August 13, 2012 Robert Either will work. And no, it will not have any words about automatic transmissions on the label (the original product did). It does not fix anything, just thickens the fluid and will slow leaks. Willie Link to comment Share on other sites More sharing options...
buick man Posted August 14, 2012 Share Posted August 14, 2012 I use Wiggley's Chewing Gum (Spearmint) as it seems to work well as a topical pack applied generously around the leaking areas. One must clean the surfaces off first with Citrus cleaner and then use a blow dryer to dry the areas throughly before applying the gum. Then apply an ice pack over the work area to set the gum in place and make it hard like the gum under your seat right now. Link to comment Share on other sites More sharing options...

Guest chevy_dude97 Posted August 14, 2012 Share Posted August 14, 2012 (edited) key words "temporary fix"adding higher weight oil can increase pressures and restrict flow in vane pumps.have I heard of this fix? Yes. Will it work? most likely will slow a seep, but not a flow. Also consider a rebuild very shortly along. And as a reply to the above posts regarding chewing gum. I suggest having a small tube of "pig putty" in your glove box instead of chewing gum.The pig putty you can apply to a wet surface and in most cases would be considered more of a permanent repair, or at the least a sure seal till your next higher assembly repair.

Guest shadetree77 Posted August 15, 2012 Share Posted August 15, 2012 key words "temporary fix"Exactly. There's just no way I can afford to get the trans re-built any time soon. So this is an attempt at slowing the problem so I can finish out the summer driving the car on the weekends. A band-aid if you will. I'm usually not a proponent of such "band-aid" fixes but when you just don't have the cash to throw at the problem you gotta' do something.

Guest wildcat465 Posted August 16, 2012 Share Posted August 16, 2012 I recommend Lucas Trans Fix P/N 10009. Swells seals to slow leaks. Don't believe the "Stops Slip" claim on the bottle in a Dynaflow. Caution: Does not smell as good as Big Red or Spearmint. Doesn't taste as good either.

buick man Posted August 16, 2012 Share Posted August 16, 2012 Well just think of the "Gum" treatment method noted above, as just another form of the New "Austerity Measures" that are being candy wrapped and put out there for general consumption as of late. - Effectively leading to the same failed results.

smithbrother Posted August 16, 2012 Share Posted August 16, 2012 Just remember, WHAT EVER YOU DO, YOU DIDN'T DO THAT, SOMEONE ELSE DID THAT, don't forget that either my friend. lol.If you use ABC gum, (ALREADY BEEN CHEWED), then that is PROOF YOU DIDN'T DO THAT BY ALL BY YOURSELF. If you go to the theater tonight, you might get lucky and find some soft gum under your seat, such would save you some cash.Just my TIP OF THE DAY,Dale in Indy Link to comment Share on other sites More sharing options...

Makes it much harder when you're working outside under a shade tree with limited tools you know? I'll probably call him next week sometime. Need to try and get an idea of when he'd be able to work on it and a rough estimate on the price so I can know how much cash to snatch from the liquor store. On a serious note though, the leak is getting worse and I can't keep driving it like that. I'd much rather stop driving her now and save myself from having to buy a whole new Dynaflow rather than just getting this one rebuilt. Ahhhh well, at least I got to drive her a little bit......

If she is not slipping and shifting fine is it necessary to rebuild the entire transmission? Remove the transmission and replace the offending seal. Reinstall. I don't recommend the transmission stop leaks and anti slippage chemicals. I have seen these cause more problems than cure. Link to comment Share on other sites More sharing options...
old-tank Posted August 17, 2012 Share Posted August 17, 2012 It's too bad the STP didn't help. I doubt that those seal swelling agents will work knowing the history of your car --- the seals are probably rock hard and resistant to any swelling.Willie Link to comment Share on other sites More sharing options...

I don't recommend the transmission stop leaks and anti slippage chemicals. I have seen these cause more problems than cure.True enough Chris. I have plenty of screwdrivers and wrenches. However, I was referring more to the need of a second jack for the transmission and a set of 4 heavy duty jack stands. I have 2 smaller ones now but I want to buy 4 bigger ones to do this job. I think I've almost got my wife talked into slicing me off a little bit of her school loan money that she gets this month. Looks like a trip to Harbor Freight is in order soon. By the way, the transmission was behaving itself completely. No loss of power or "slippage" at all. The only thing I noticed that was a little strange was that going down the open road if I gave it a little more gas to get up a particularly steep hill or just to gain some more speed, the trans. made sort of a groaning or howling sound. Low pitch, kind of quiet. Hard to even notice if you don't pay attention. And that's ONLY at cruising speed. As for re-building it, I haven't decided which way to go yet. In a way, I want to go ahead and get it done so I don't have to take it out again when something else fails. The other seals inside the trans. are 60 years old too and who knows when something else is going to break loose? But then, I also don't know when or if I can come up with the money to do a complete re-build. It's likely I may be able to replace a simple seal on the converter/pump and stick it back in there. That would be the quickest, cheapest, and definitely easiest way to go. :confused: Guess I've got some decisions to make. In the meantime, we checked the pump cover bolts today. All were tight except one. One of the bolts was REALLY loose. Like, about to fall off loose. We torqued it to spec. hoping upon hope that the leak would be cured but.....no dice. We started it up and ran it for about 5-8 mins. I took some video of the leak. You can really see it good at about 0:40 in the video. Looks like Lucy is down for the count. I can't bring myself to drive her like that.<iframe src="http://www.youtube.com/embed/fNnVEzanICM" allowfullscreen="" frameborder="0" height="400" width="500"></iframe> Edited August 18, 2012 by shadetree77 (see edit history) Link to comment Share on other sites More sharing options...

And looking at the video the trans is using more fluid than carb is fuel. Look at the bright side at least you can say you did a trans flush...

avgwarhawk Posted August 18, 2012 Share Posted August 18, 2012 Yep, she is leaking good. And that sucks. I have not been into one of these dynaflows. If it is similar to today's transmissions, the seal between the convertor and transmission housing is leaking. I'm still of mind to dropping the trans a replacing the seal. Reinstalling. I can understand your reasoning with the other seals. Replace all the other outer seals that are replaceable. She pulls good and acts right. Just a nasty leak. I would go after the leak for now.

Ben Bruce aka First Born Posted August 18, 2012 Share Posted August 18, 2012 I agree with Chris. Pull it and replace all seals and gaskets that do not require opening it up. And pulling the rear end out so the Dynaflow can be dropped is not too bad. I have had mine out twice . Once to replace torque ball parts and second time to change gear set. And I am an old fart working alone!! I bought the less expensive, non hydraulic tranny jack from H F. Wish I had payed the extra for the hydraulic. Good luck.

buick man Posted August 19, 2012 Share Posted August 19, 2012 (edited) Disclaimer Note: For the purposes of this video we did not use a pan to catch the fluid as the director felt that by using anything other than the concrete such as a pan, would take away from needed "drama" necessary for this take. - "The orphan bell housing, crying big red tears, streaming as they will down onto the cold concrete, as the camera slowly fades the scene from our view.But on an upper note, one could attach a sump pan wit a pump and direct back into the fill tube.
