transmission leak

<table>Okay, so nobody thinks a $50K car with atransmission with irreplaceable parts should be used as a
lawn mower.Buthere is a serioustransmission questionfor Dave or anyone else. Where can the
land transmission loseover a quart of fluid in 100 miles of 55 mph driving? It's not migrating into
the water transmission.The lost fluidseems to be staying inside the bilge and the top of the transmission
case is very oily on the outside, including by the small breather hole with the little spring loaded cover.
(It apparentlyis the older style transmission case with the small breather hole for the land transmission,
not the larger removeable cap like the newer transmission cases have.) Can a certain condition be forcing
fluid out of the breather?

Back in July, I did have the front cover off of the transmission (while it was left in the car) to replace
some propeller bearings in the water transmission parts, but I only took apart water transmission parts, not any land transmission parts.At the time, I let transmission fluid get all over the bilge when the cover came off so I always thought the oily bilge I kept getting was from that old oil washing around. After the first (100 mile) trip from my Dad's to my houseafter replacing the bearings I checked the fluid in both parts of the transmission, both levels were fine, not low(assuming you fill each part up to the level of the upper plug and if asmall amount of fluid trickles out when youremove that plug later on, the level is fine.) Drove to Celina and back (200 mile round trip) then another 150 miles or so, then checked the fluid and it needed like a quart and a half in the land part, while the water transmission was fine. Put new fluid in Wednesday night, drove 100 miles and it's down a quart or so again. I don't think I messed up the new gasket or either surface of the front cover or the transmission when I took it off or put it on. Where could the fluid be escaping? My Dad said to jack up the rear wheels and put it in gear and see where fluid comes out but I don't know that I'd see it. Any ideas?
Thank for any advice!

P.S. We had put new 2-17-12 oil seals in last year when I bought it, but I don't think it's leaking there, since it is so oily *inside* the bilge area.

I agree with the advice to look for leakage outlets; that quart is going <u>somewhere</u>. Just to help your imagination, you can lose land transmission oil through the input shaft oil seal (that's at the rear of the land transmission, next to the clutch). This is bad, since eventually your clutch plate will get oil-soaked.</font></span></font>

<font face="Tahoma" size="2"><span class="765223401-02092006"><font face="Century Schoolbook" color="#0000ff" size="4">You can also leak through the seals at the driveshaft splined hubs, dripping land transmission oil out into the donut-shaped transmission-to-hull water seals. This is particularly tricky, since debris (sand, twigs, muck) often build up in there too, and may absorb a lot of oil leakage before oil begins to dribble down the inside of the drive-shaft housings. This is even badder, since oil leaking out means that water is also probably leaking <u>in</u> to the transmission (unless you never swim). BTW, running the Amphi, in gear, with hull blocked and the rear wheels spinning free, will put the least closure pressure on those transmission seals, so they will be more likely to leak then. Just be careful that you don't launch your Amphi through your garage wall.</font></span></font>

<font face="Tahoma" size="2"><span class="765223401-02092006"><font face="Century Schoolbook" color="#0000ff" size="4">Water in the transmission oil doesn't show right away, since the oil floats on the water, and you may lose some oil out the breather before noticing that the oil is foamy (a bit like a milkshake).</font></span></font>

I am having oil in my bildge to, after 30 mile on land althow not one drop overnight. I have the older style also with the small vent hole. It took 3 qt. to fill it to the upper plug after I dissasembled it last winter. I read in the repair manual it should take 2 litre. So I am going to let it go and see if it is just to full and quits leaking at about 1 inch down. Scott W.
