That's NOT 800 series trans!!! That thing doesn't come apart like I told you. Looks like you gonna have to drop the tranny and split it in half to get to it. Look at it from this angle...still not a big deal and you get the opportunity to clean the old grease out and lube it all nice and fresh on the inside!!!
Thanks Jack and Boobala. That's what I was fearing. Not a big deal though, like you say, in the long run I'll be more knowledgeable with my mower and hopefully prevent future issues.
Any recommendations for transaxle lube and sealing (silicone instead of gaskets?) to save paying the John Deere premiums?
