I have 3 Polaris bikes, and two of the three are leaking tranny fluid. Is this common? I did a search and only came up with two similar posts, and neither one got a response. Both of these bikes are fairly new, an 03 250 Trailblazer and an 04 Trail Boss. They appear to be leaking at the seam between the cases. Anyone else have this problem? Is it an expensive fix? I bought both of these bikes used, from two separate parties. Besides the leaks, both bikes are in very good condition. Thanks for any help, I hate leaks!

 

Anyone?

 

I have never seen one leak at the seam.

If so you must remove the trans and split it and use silicone to seal it back up.

Replace the seals while you are at it.

And when you are done fill the trans with Castrol Syntec 5w50.
