Hydro Transmission strong in reverse, weak in forward, Wheelhorse D200

[CliffordK]

I've got a Wheelhorse D200 that I'd like to do some work on this spring.

The hydro transmission is strong in reverse. But, it barely has any power in forward.

The previous owner messed around with the linkages, so I think they are tight, although I'm not too keen on his work. So, I'm thinking it is time to clean the transmission & replace the seals.

However, how can I be sure the problem is in the pump vs the transaxle?

Did you ever get this fixed? I have a 200 with exactly the same problem. What did you figure out, if you don't mind my asking. I'm looking at trying to fix mine this summer.
