    I have a K58 mounted with the input shaft horizontal to the ground, shaft driven from the engine. It has a remote fill bottle. The manufacturer suggests to keep the bottle full. I am concerned that there may not be oil in the final drive area of the housing as they are segregated. TT suggest filling this transmission from a drain plug upright position. Also what is the fluid capacity. Thank you

    • ggraham says:

      We are currently working on a procedure for the oil fill with Toro. We should have it soon and I will get it to your email address as soon as I get it.

    My barcode does not look like this one. All in one line at top of barcode: tuff torq 787Q08240010 SN: 7D-Roo30167

    • ggraham says:

      Yes, that is a right side for a TZT 7D. Since that is a John Deere I am required to send you to a local John Deere Dealer or you can contact the John Deere tech Center at 800.537.8233. John Deere is now servicing their own transmissions

  • David Lilburn says:

    I have a Husqvarna TS 348 with I think 46LR Transmission and it appears to always be in locked mode. ie I cant go round corners without scuffing. Dan you please help.

    • ggraham says:

      I am sorry but that tractor has an always-on limited-slip differential. You would need to take turns wider and slower to avoid the issues with it tearing up your yard.

  • Jeff Kruszka says:

    I have a 2001 sabre 2554 the tuff torq tag is not readable. Can you tell me which trans is in that. Thanks for any help

    • ggraham says:

      The best thing to do is to get the serial number of the tractor and call a John Deere Dealer. they can get you the John Deere Part number and I can cross that.

    how oil does a tuff torq 787q0684140 SN: 13d-L001468

  • Lily Spires says:

    If I tell you the model number of my Cub Cadet can you verify the transmission number that was sold on it? Sent it to the shop and I have questions if I got the original transmission back.

    • ggraham says:

      I do not have great tractor data. Your best bet is to check the bar code sticker on the case of the transmission. Otherwise, you can contact a Cub Cadet dealer with your serial number of the tractor and they should be able to give you their part number and I can cross that number.

    • ggraham says:

      I do not have good tractor information. I would need the serial number off of the transmission itself. It is usually located on the case of the transmission close to one of the axles. Normally you can see it from the rear of the tractor. Armed with that I can get you what you want.

  • Scotty says:

    Hello. I have a 2012 D110 lawn tractor that has leaking axle seals. I am having trouble figuring out if the transaxle is a T40A or T40J as the tag has been destroyed. I need the part # for the axle seals and which type of oil, and how much to put back in it after I drain it and replace the seals. Also is there any kits that I should get and change on it since I have to take it out?

  • Greg R Marazzi says:

    1993 94 john deere barcode on transaxle. Its only stamped 080102. What model transaxle do I have?

    • ggraham says:

      There were a number of different transmissions installed in that tractor. The easiest thing to do would be to call a John Deere dealer armed with the tractor serial number and they can get you the part number for the transmission. More than likely I do not have parts for those transmissions because they are obsolete.
