1.23 Transmission leak

I went to pet the SN yesterday & found that the transmission is leaking. It is not coming from the shaft seals nor the hose connection. It was wet right under the rear case joint, but that may just be the low point. I see from a site search that there is a drain plug that is prone to leak. I am hoping that this is my problem. Can someone tell me where the plug is? I didn't notice any plug when feeling the trans bottom for the ATF presence, but I could only access the port side.

Thanks

Heres the drain plug. I know mine wont leak- its basically welded on there. Im sure Eric might have an idea what seal is causing the leak.

I did the front seal on my PP last year and it was not too bad. Probably one of the more advanced shadetree mechanic jobs that you could tackle but once you do the bottle jack trick, you're good to go. The Toyota OEM tire jack works wonderfully as well.

i would say its leaking from the pipe plug seeing that it has been sitting, the oil is not near the input seal while sitting, it is a static leak, you may have to raise as suggested....dont use stop leak better yet, use stop leak im a little slow

Ive spoken to Eric a few times on the phone. He's pretty slow. JBear told me thats typical, considering where he's from.

Its aluminum, so its very light. It only takes one person to remove it.

Tim: How is it that you always have EXACTLY the right picture when ever anyone needs some "look-see" info?

The word seems to be getting around about brunstucky eric.

I left some down the hill in Strongsville...but I swear I have never been with a brunswick girl.

Make the trek up to the boat again today (50 miles 1 way)to check on my leak. Drain plug is not the issue. It appears that the oil has been coming out the vent. There were traces of oil around the vent & down the starboard side, inluding the mount area. I sucked about 6 ounces of ATF out to get the level down to the full mark. It must have been siphoning out with temperature changes. The boat is in a level position.

I cleaned it all up again. Hopefully that is the end of this post!

There are definitely some slow folks over in Brunstuckey! Eric is not even close to what I have come to expect from that area.

Randy, Hopefully you over filled it. If not, a high level in the trans would only be caused by water entering via a leak in the cooler. If it happened late in the season, you may not get the typical "strawberry milkshake" because there wasn't enough run time to mix the water into the oil. Yes, in this case, water does mix with oil! There is a additive in the ATF that intensionally does it. This is so if you do get water, you will be running a blend and not getting a slug of only water through it. The same is true of lower unit (outboard and I/O) lube. You may consider checking your cooler.

obsessed, I only tell this to my closest of friends so please try to keep this a secret,In the spring warm the boat up to operating temp and fill the trans to the top with atf, run for a little while and turn off, remove the return cooler line and put in a bucket then fire the engine up again, when oil stops coming out from the oil line turn the engine off, this method gets 99% of the oil out of the trans and along with diluting it with clean oil from filling it to the top. re-fill and your ready for spring, try to shift trans in and out of forward and reverse to evacuate the piston cavities, this way wont hurt a thing

Greg you too can also do this with the Borg Warner, remember diluting the oil with the new is key to this. Always do it on the return line to the transmission because it also empties the cooler, with the BW it does not get all the oil out because of the strainer location so if you can try to suck the rest out after you drain in this manner

Eric - the secret is safe with me.

BTW, this is how I changed trans oil in my car.

Thanks a bunch.

Now time to tune into the Superbowl.
