Sounds like your tranny is at the end of it's rope. I'm not big on liquid mechanics. But some Trans X from Auto Zone just might get you home before it's totally dead. Mike Kelly can tell you about this idea. Bob Dunahugh

A stop leak is something that should be carried in all our GMC's. Saved me once with a heater core leak. Replaced the core when we got home.

If you yourself paid for a trans rebuild. Thus know the true history. Fine. But if that's not the case. Or the PO told you a trans rebuild was done. I'd have a can of Trans X in my GMC. The trans that we are using now was from our burned GMC. It now has about 31000 miles on it. I still have a can with me anyway. $6 may beat a chance of a hook. Bob Dunahugh

I have been told that ground black pepper can be used in an emergency for
stop leak.

I'm not a big fan of add-on "snake-oil", but I must admit to one very
dramatic demonstration of radiator stop-leak's effectiveness: Many years
ago, probably '99 or so, Jim Bounds drove my GMC a mile or two to check it
before doing wheel alignment. When we returned to the shop, there was a
steady stream of water shooting out of the lower portion of the radiator
where some road debris had hit and punctured the core. He sent a runner to
the parts store for a can of Barr's StopLeak, which he poured into the
radiator. Within a few minutes the leak stopped. I never had any leakage
from that radiator again before replacing with an aluminum one 10+ years
later! Honest Injun!

I have a jar of Barr's stop leak in our GMC. I put the entire contents in the time I used it. It stopped a fairly large leak. Got me home. As to the Trans X. Again the entire contents. I've seen Trans X get 4 GMC's home. With one other GMC. Didn't help. $6, and a few hours of messing with it. Cheep way to maybe get back home. I've never seen it work in under an hour. One took a day. Also seen it work for years after installing. I agree with Ken Henderson. Most of these kind of products are just snake oil. Bob Dunahugh

Don’t use a stop leak that is in an oil base. Barrs and others sell that. The oil can interfere with the antifoam additives in antifreeze. So be sure to use a dry powder.

General Motors, for over at least the last 70 years has put stop leak powder into their vehicles as a preventative measure. They use ground up ginger root. There used to be a Vernor’s Ginger Ale factory in Detroit. Someone found that ground up ginger root would seal up small leaks but not harm the water pump or other internal engine parts. You can buy that stop leak in pellets about 1” in diameter and 1/2” thick. Usually in the plastic bubble packs at the parts store.

GM would put two pellets into a V-8 and one into a six cylinder on the assembly line.and
They are sold under the AC/Delco label and also other brands. Here is a picture on Amazon: https://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=stop+leak+pellets

Back in the 70’s both DuPont with their Xerex antifreeze and Dow Chemical’s antifreeze advertised and sold jugs with stop leak already in the antifreeze. DuPont used tiny styrene plastic pellets (which were made by Dow as water softener resin) and Dow used ginger root powder.

Just so you know not to waste the time and effort, Blackstone reported that our engine had coolant in the lube oil. As soon as I saw that, I when on the offensive and both monitored coolant loss and did lube oil changes regularly. I was still unsure, so I borrowed a cooling system tester and put pressure on the cold system for a day. It did lose some, but not a lot. So, I loaded (I do mean loaded) with the Barrs Leak pellets. the next three changes still showed coolant present.

I case you weren't reading a few days ago, when I got the intake off, there was a visible leak path.....

Emery, years ago when I was partners in an automotive machine shop, we
remanufactured cylinder heads, mostly foreign car stuff. Particularly Saab,
which were pourus sand castings. When we removed the core plugs, we always
inserted a pill inside the casting before replacing the freeze plugs. They
were as you described them, dark grey or black in color, and with coarse
fibers of some organic material visible. They were represented to us as
"what the manufacturer used". We also epoxied a metal disc on the outside
of the freeze plugs. Their purpose was to tell if the head had been
overheated. They either changed color or melted if that was the case. Kind
of an insurance policy against sloppy mechanics screwing up our good work.
We had a test tank to pressure test our heads with shop air, as well. The
discs dissolved when exposed to hot antifreeze. We had very few come backs
for leaks.

OK. What is it that you don't believe? The size of the pellets or something else? Smile Smile

Emery,

I am pretty sure that Todd knows you (at least by reputation if not personally) and he is just pulling your leg (a little).

You just got to admire the fact that we do have people writing here that really know their stuff. If you don't believe how different this is, tell me and I will link you to some other boards that I read for amusement and not education.

I've put those pills in many engines over the years. I remember some using a different nutshell, maybe almond or cashew, as the media. GM required them for any warranty work involving engine disassembly on the Northstars.

Terry, don't forget the notorious 4.1 or 4100 either. One overheat, and
they were kaput.

Jim, I try hard to FORGET those damn things...I despised working on them when they came in for ANYTHING. Sometimes it was an onus that spread to whole vehicle. They had some nut and bolt sizes on those engines that didn't fit SAE or metric tools and just changing the belts was a super bitchin' nightmare, sure to spoil your morning when you saw it in the parking lot. The 4.5 was better, but those were always run until 4 or 5 things were broken before the owners brought them in on the hook.

Yes, Terry, Cadillac has had some DOOZY engines over the years, starting
with the first overhead valve engines in the late 40's. Those 331 cu in
engines were known for cracked cylinder heads and flat camshaft lobes.
They evolved into some very high performance stuff in the Eldorado
models. Dual 4 barrels, dual exhaust, very special heads with solid lifter
camshafts, high volume oil pumps etc ALL ACROSS THE COUNTER at your local
Cadillac dealer. The presidential limos had some real fire breathing stuff
that Ordinary People couldn't get their hands on, either. The best of the
iron V8 engines was the 390 cubic inch. Single 4 barrel version cranked out
345 horsepower at 3200 rpm, and a heck of a lot more than that at 4500.
I had a 61 coupe deVille small roof with a 390 High Output V8, it
would eat 500 cubic inch Eldos for breakfast. Top end them too. Last of the
rocker shafts engines. Those stanchion rocker studs in later engines
crystallize and fracture right where they come out of the towers. Throw all
that cylinder head gear away and replace it with shaft mounted needle
bearing rockers, like CadCo or Mondello and it makes a sweet setup.
Cadillacs? I've had a few. A 49 sedanette, 2 1951 Sedan deVilles, a 56
coupe deVille, a 1977 Sedan deVille, and the 61 Coupe deVille small roof.
No modern aluminum engined stuff, No V-4-6-8, s, or Northstars. A Canadian
friend has one of those Corvette powered all wheel drive cars with the
magnetic suspension. That thing is FAST and handles.
