    These are very solid reliable transmissions. There is a 3020 power shift on the dairy I help out on with well over 20,000 hours on it and the transmission has never been apart. It was bought new in 1967 and for years it ran the feed cart until the feed cart out grew the tractor.

      Nice! You know member when a tractor got two five or six thousand hours and a guy had thought well it's getting up there in age. 30 years later these tractors have that 20-plus thousand hours and they're still going

    Good afternoon, I purchased a 4640 this winter planted soybeans and started to do some cultivation with a 8row buffalo. I had problems with the pto lifting and so I changed the filters and it was full of glitter. It seems to shift fine but I pulled them out and replaced them. I did not change oil yet but I thought I could finish the field. I am changing oil. And second set of filters. Do you have any suggestions of where to test the oil and make to catch something before it goes south? Thanks

      Your local Caterpillar dealer can do an oil scan, they sometimes can tell the type of metal and tell you it's a gear or bearing
      Could be bad brakes and the brake disk grinding, could be bearings on the axle or trans.

    Amazing work!
    Thanks alot for the tip,i added regular talc powder to my corn seed(1 pound per bag🙂),problem solved!
    I want to buy a JD tractor in the 135-150 HP range, full mechanical shifting,only with hydraulic HI-LO.
    The 3650 is 120 HP max from what i know,so it s a no deal..

      Not familiar with the 3650, but if it's a similar platform as like a 2955 they can be a nice tractor, but that hp gets you a little out of range, can you find a 4250 kind of tractor?!

      I have several 15 speed power shifts around here from cattle operations that are at 25,000 hours and the Transmissions have not been opened up
      With anything used you never know how it's going to turn out
      The 15 speed is very reliable and no electrical control.
      It is also a tractor that with a John Deere tech manual you could rebuild yourself. It's not the greatest loader transmission simply because you're always sliding that handle for shifting there's not a shuttle shift

      On these power shifts usually you get lucky and you have symptoms that send it to the shop before complete catastrophe. In M case is a couple Grand can actually go a long ways
      The first thousand dollars will just go to gaskets, seals oil filters basically just the parts to do the job.

      @ndrancher4041 1-4 in reverse are the same clutch packs other than the forward/reverse pack.
      So if you stand on the brakes in reverse and can't get it to slip, that tells us the gears clutch packs are good must be forward pack. But you say 5-8 work good. That is backwards, normally 7 and 8 start slipping first.
      That is a tricky one.
