PCM 1.23:1 Wanted

Someone threw a banana peel in my tranny! Now I need a PCM 1.23:1. Any help out there?

sorry pcm 40-1
1.0/1.0

what is wrong with yours?

Paging Dr. Lavine...

all i can say is they cant take low oil like a Velvet, once you glaze the plates from slippage, they lose thier ability to hold.....keep an eye on it.

Another thing, has anyone tried using any additives as a temp. band-aid? Stuff like Lucas trans additive or the stuff made by 'Gunk'?

Well, you can put a additive in the trans but that's only if you want to give it a quicker kiss of death.

You need to understand that the marine automatic trans really has very little in common with the automotive trans. Both simply use the same fluid. The marine trans does not have the torque converter in it where these additives may help by changing the viscosity and modifies the friction of the fluid. A marine trans simply uses a hydraulic pump to apply pressure on the clutch packs (not a torque converter) which engage/couple the engine to the prop shaft. What used to be done manually with the big shift lever through the floor is now simply done hydraulically.

Oh, I can tell the additive tranny's, twice the price to rebuild, they swell the rubber up and cause real problems, dont use them

CHANGE YOUR TRANS COOLER IT'S LEAKING INSIDE AND THE FLUID GOING OUT THE EXHAUST. IF THERE NO FLUID IN THE BOAT IT'S GOING OUT THE BACK INTO THE WATER.

No name.
Well, we now know the real problem!! Tubing!!! Just kidding here but do try something with a higher skill level like skiing or boarding.

Regarding the water in the trans, I think you got a little side tracted here about the oil comming out the exhaust. That's real hard to detect plus it's not the concern. With a leak in the cooler, the concern is the water getting to the trans. The best way to check out the cooler is to pressure test it to make sure there isn't a leak between the oil and water circuits.

The oil in the bilge isn't related to the cooler. it's probably the front seal and there is a reason for it to leak.

Keep a eye on the color of your trans fluid and do a pressure check on the cooler.

Naughty93 wrote: That sounds a bit more plausible. Cooler leak/water into the tranny/overflowing the tranny causing it to blow the seals thus the frothy strawberry shake in the bilge. Does that sound about right?

If water is going in at the cooler, then oil is going out the exhaust too so the trans isn't being overfilled. I'm sur Eric will be alone and will comment but the front seal issue isn't due to the trans overflowing but rather a sloppy pump. This allows oil to flow around the pump and pressurizes the area at the front shaft seal. 405 hours are on the trans! Still, it may be time for a rebuild.
