    I have a 97 Craftsman Hydrostatic trans and I was wanting to change the fluid in the trans but not sure what to use a replacement so I was wondering if you guys could help me. I was thinking of Amsoil but not sure. Thanks :usflag:

    Depending on your tranny it may not be serviceable. Just not enough info posted.

    I have a 96 or 97 23 hp Koler Craftsman garden tractor that is a hydro. The transmission is seal. You can not change the fluid.

    I looked last night and I can't find a drain plug on it so it must be a sealed unit. Does anyone know why and how do you service them if needed?

    Really there is no service. If it shoot's craps then you have to change it out. I should last a long time though.

    Until you post some model #'s, how is one supposed to even tell what unit you have?
    Either look on the transmission for some ID or post the Craftsman #.
    Something like 917.xxxxx

    As khouse mentioned these units are considered non-serviceable by consumers.

    But, If you insist on servicing/changing the oil in this unit it can be done.

    You must remove the trans-axle from the unit, Remove part reference #113/114 vent cap from the top case then flip upside down to drain. Catch the oil and add the same amount of 20w50 engine oil then re-install cap and put back in unit.

    Personally, I wouldn't monkey with it if it's working fine.

    Like Restrorob said "Don't monkey with it"
    When you turn it upside down you can dislodge trash that has settled in the bottom of the unit. This could cause some trouble. The tranny will outlast the mower in most cases.
