Guys,
Have you ever used brake fluid as a trans seal "conditioner" to help with what appears to be a (slow) leaking front seal of the transmission I don't get to drive my car often and I feel that may have led to seal becoming deterioated and leaking ....opinion?

This was recommended by someone but I've never heard of this remedy and I am very reluctant to possibly mess up trans.

Any suggestions on this "remedy" and/or other options? Please advise soonest.

Thanks in advance,

Tony

Only time I ever tried a "seal swell" type of miracle
goo, the front seal blew out entirely and there went
the $150 I spent on that car. Not to mention the
couple of bucks for the can.

I would not do it on a car I was fond of.

On converter swaps the little O-ring on the snout is
a second possibility for weepage, this should be
changed as it hardens up and may not seat right
to the new converter.

Not very handy at this particular point in time tho.

unless you are selling the car, do not put any brake fluid or ANY type of stop leak in it ever.
it will ruin more than just whats wrong now.
brake fluid will swell the clutches. to the point that your tranny starts eating it up till its gone.
good luck.

I am going to be doing a fuddle 3400 stall on my 99 t/a with 113k within a few weeks and wondering what the "o ring part on the snout" is called or a GM part number so I can potentially do this when my friend and I put my stall in. (my friend is the service manager for the local toyota dealer so we will have a lift and likely all necessary tools for the saturday install)

Thanks in advance

I had one in my hands this morning but didn't look
at the P/N. It said something like turbine shaft
seal in GM-ese. The parts counter guy can turn
it up for you, it was under 5 bucks if I recall.

Thanks for replying guys.

The converter install was about 2.5 yrs ago. It has only started leaking the last few months...so I guess there is no other option but to drop the trans and check for the leak.

If I have to do that,I'm going to step up on the converter...hahaha

Thanks,

Tony

How many miles are on the b1tch? Maybe you should just take it to a pro and have her rebuilt while its out. No point doing this again at a later date, especially of you're going with a higher stall and going to beating on it more. The brake fluid will work, but it will swell every seal in the tranny, and eventually lead to its demise. So if you'er looking for a quick fix for about 6 months do it, but only like 1 oz. Otherwise dont do it. If this car is older and you have some miles on it, you could be looking at a bad pump o-ring also, or possibly even the pump bolts, which have washers behind them. Theres more to this stuff guys than just a front seal. Your pump bushing could also be going bad, which will cause the torq. conv. to run out of round and eat up seal after seal unless you replace the bushing too, which requires pulling the pump out, and apart. In all honesty, save yourself the trouble of doing this multiple times. Pull it out, look at the neck on the converter for wear signs, seal grooves, etc. The pump bushing may have started to walk and is pushing the seal out. Pull the unit, take all this info ive given you, and take the unit to a pro and tell them you want it re-sealed (if its a low mileage unit) and you will get new front and rear seals, pump bushing and o-ring, new pan gasket and shifter linkage seal. Probably cost you about $250 if u pull it yourself and take it to them. Much cheaper and painless than messing with it yourself and having to do it 2-3x just to end up in the same boat.

adding brake fluid to the transmission is what we do to derby cars that have bad trannies in them. don't do it to your car, it tears the hell out of the transmission...brake fluid isn't chocked full of what you'd call lubricity.

it sure will make the clutches sticky for a few races tho.
only way it wont slip and burn up. well, its gonna burn up, but still. brake fluid helps them when they are DEAD.
haha. engineering at its best.
