Probably both, but pump is inside, pretty much integral to hydrostatic drive on those models. There are other possibilites so what I would do is cap off the two small outlets with 1/4 in steel lines coming off top of control plate on side of hydro. Use steel caps. This will eleminate all external valves to see if it still acts up. You will not have a foot n inch pedal though with those capped off so be careful. Speed ratio lever will be only control of hydrostatic drive speed or stopping. If it works the same capped off I would test servo pressures though before I tore into the hydro. If it works fine capped off then you start looking at the control capsules and foot n inch valve.
