Easy stuff first:
Check your hydraulic filters if it is anywhere close to the maintenance interval.
If you were using a three point bale fork, check the three point piston seals.
The more serious:
If you shifted from forward to reverse while still moving and at operating RPM with the syncroshuttle transmission, I would suspect the hydraulic shuttle clutch is worn out.
If you have the hydrostatic, shifting at less than operating RPM or while moving will cause the frictions in the transmission to shed a lot of material and plug the hydraulic filtration system. Eventually it will destroy the transmission. If you have the hydro tractor, let it completely cool and change all the hydraulic and transmission filters, then try it.
