Hydraulic shuttle shift is not hydrostatic ? I was thinking clutch. Now just have to figure out how to get to it.
No a hydraulic shuttle is not a Hydrostatic transmission.
They are completely different transmissions.
Does it act exactly the same forward and reverse?
If it does then it's unlikely that it has to do with the shuttle clutches and it has to do with the main travel clutch.
There is 2 possible main clutch types for that model, single disk and dual disk.
Let's figure out what clutch you have, that might help us troubleshoot further.
Look at this part of the clutch pedal and tell me what clutch pedal you have
Dual clutch pedal, note dual arms (yellow).
Single clutch pedal
Note single arm (green)
