What did you take apart to change the fluid?
hi. no drain on the casing, removed the bottom cover.. also as i bought this mower second hand,when i found that the oil reserve tank was full of dirt i decided to clean the whole trans mission..replaced every thing as it was,or i thought so.. obviously i stuffed it up..cheers

There is a piece in the pump if you put it in backwards you get the problem you describe.
hi can you please let me know which piece it is,is it shown on a diagram of the transmission,cheers

I meant to say the motor not the pump. The block that slides in with the motor pistons can be put in backwards and that will cause the trans to operate backwards

It sounds like it is the hydro unit with a two bolt cover for the gear pump. That cover if rotated and installed backwords from how it came of, reverses pump flow. Remove it and install 180 degrees from how it is now.
hi .thank you for your reply.it is a tuff torq k46.i have reopened the transmission.and removed the clamb shell.this motor has no two bolt cover but it does have three bolts hold the pump and motor into the the base.. can please clarify where i would find the cover for the pump.
i have included some photos of the hydraulic pump and motor mount..
