Tranny oil leak

I have an oil leak in the 89. symptoms are that it appears to be comming from the input shaft seal & leaking out into the bilge.

It's 1.23:1 tranny

Researching here it seems that the tranny might be over pressurizing & forcing fluid past the seal. Is this the pump.?


The delema I have is that there is no local CC dealer to me, and that my local ski boat agent isn't interested in looking at it.

Is this something that I can repair myself or can I take it to an auto tranny specialist.?

Thanks Pete,
Yes I was a little worried that an auto trans shop might not know too much about them, but if I can be stepped through it I'm sure I will be able to effect the repair.

My tranny cooler does have a small water leak at the outer seam. It's only a slight drip. This just needs to br re soldered. This wouldn't be contributing to the problem.?

on the 1.23"s the front shafts will pit and cause a seal leak, highly unlikely the pump is bad. start with a seal and emory cloth the shaft,and install new seal

What is the best way to drain the oil.?

Is there a drain plug.?

Eric do you supply these bits or do I use SkiDim or similar.?

Forgive me as I have sinned.!

I'm just going to get my local "cough" Malibu "cough" dealer fix it. I spoke with them about it and they mentioned that they see the same issue with their ZF transmissions on the mals. Seemed to think it would be a pretty straight forward / easy fix.

I just don't have the time at the moment with current work commitments. I have a buyer keen on buying the 89 & I'm still trying to finish off the new trailer for it.
