965B Transmission failure

Just had a major explosion inside the Cat 16 speed that was possibly caused by failed thrust washers. The updates were done at 1800 hrs and now the transmission has a major failure at 4400 hrs. Oil changes and filters have been done and since I have owned the tractor the filters have been cut regularly and show nothing caught in the filters. Is this normal for these transmissions? I thought these were supposed to be almost bullet proof. When it blew up it was on the road at full speed. Is there a connection there to high speed and what appears to be thrust washer failure again??? Is there any expectation of some kind of help from Mother Agco since this is a failure of an issue that was a warranty update. This is very disappointing that the component that I trusted the most of the whole tractor has had a catastrophic $$$$$$ failure. Any input on this would be greatly appreciated.

Perhaps it would be worth a call to CAT to see if they have had any problems

I was of the understanding that the thrust washers that were updated to thrust bearings were in the differential carriers in the axels, not in the transmissions.

You could be correct. My info is pretty vague, but my dealer says the transmission was "rebuilt at 1800 hrs" as part of some program I believe. So what would have been done in the tranny? As far as they are in the teardown yesterday they are thinking it was thrust washers that seized that started a chain reaction of destruction.

I always get concerned when I see a machine with a major component like an engine or transmission rebuilt, makes you wonder if it's ever really the same as it should have been?

Sorry to hear about your unfortunate breakdown.

When our 865 was nearly new it had some sort of update like you are talking. The only difference we ever noticed was something was off cause the rear window would open about an inch then hit a fitting on the fuel tank. We ran that tractor to 3400 hours in 10 years, no tranny issues, then traded it for an 865C, speaking of which we are interested in selling, just turned 100 hours on it yesterday.

Why would you trade with such low hours? having issues with it?

This has a name now TA.
Your transmission did a "Prentice"!

Being honest may not get you a lot of friends but it'll will always get you the right ones.

I have had trouble getting warranty out of Agco when the unit is still actively "on" warranty. I wouldn't hold my breath as to Agco coming to the table. Especially if your dealer is in east central AB as mine is!!

There is a high probability that somebody stuffed up, during the rebuild and shortened the life of the transmission.
Mother Agco will likely wean you off her teat at this point.
