Transmission leak

I have a minor leak coming from the output seal (99% sure) on a CSX 220. It is around a drop every 7 seconds when you in drive and a drop every 10 secs when in neutral. Haven't timed it with the engine off but it's probably less than a drop every minute. I keep adding and it's working great. I have two questions

I'll get a temp or pressure warning if the leak gets so bad suddenly and all fluid drains out fast, right?

I plan on having it fixed in Jan at a shop (no dealers here) when I go on a work trip, anyone see a issue with waiting that long?. We put about 3 hours on it every weekend at least.

you will lose about an ounce approximately.

hopefully you will get an overheat signal - but by then the damage could be done... IMO.

A transmission specialist would know best. which trans do you have?

Main issue, with low levels is, slipping friction disc. Which contaminates existing fluid, can warp steel disc. etc. On performance (ski)DD boats, the slipping occurs on hard right turns, and sometimes...the start of a pull.

So, if you're not asking a lot of your trans, just watch you fluid level... carry a spare bottle of fluid with you, just in case.

Did the guy you bought it from not tell you the trans had a leak?

I don't know the engine bay layout on a CSX but this is a pretty easy job. Get the prop coupler out of the way and remove one large bolt. Get a cotter pin puller and get the old seal out and tap the new one in.

No the previous owner did not say anything. When I asked about some oil in the bilge he said he overfilled the last time.

Here's some pics. The drip is coming from where the silver shaft and gold housing meet. The other Pic is the type of trans. It's no dripping around every 10 second when not running and completely cold.

There is good room to work I just want to confirm it is the output seal first.

Thanks

It was not as hard as I thought. Once I got the bolts holding the two flanges together (hardest part) and it was clear things around the output shaft were not good. The o ring inside of the retainer nut was completely gone and the flange that connects to the output shaft was worn and needed replacement. So I've got all the new parts in route; flange, shaft seal, o ring a a retainer nut. Hopefully they all get here and I'm back on the water in a week.

Sounds like you're ready to add to the intellectual database here on team talk with a write up of your repair. I'm sure we'd all like to hear and see how this all played out for you.....
