John Deere 455 Transaxle Leak

[PM Wells]

Yes, I agree, I have had this machine sitting on a jack with fender pan and rear wheels off for about a month just wanting to do everything it needs this time before I put it back together for mowing. I am learning to slow down and do it one time.

Actually I don't know for sure where the leak is. I saw oil on the floor under the machine in the fall, and would clean it up, thinking I had plenty of time before mowing started. I have waited as long as I need to because grass is starting to grow. The leak is not directly under the trans, more out in front, I did see some oil on the linkage coming from the differential lock. I haven't really felt like crawling around on the floor looking for it, but now I am going to get on with it and fix it, just wanting to cut out all unnecessary work as much as possible, I do think the axle will need to drop to get to the seal.

The differential seal requires tranny drop. Can replace the direction input shaft o rings without dropping with patience.

If you find the front gaskets leaking need to remove the pump and front cover as one unit otherwise the pump coming off of the mounting plate will drop the pinion gear into the tranny

Great RandyT,
That is the kind of info I am looking for, I want to fix it, not just play around with it, finding out the hard slow way. Thanks.

@PM Wells if you have to remove the front plate pump let me know and I can give you more insight into how to remove the correct bolts to keep the two pieces together until on the work bench.

Yes sir, thank you for the heads up. Hopefully it is a more simple fix.
