New Holland Hydraulic Clutch Pack

[BRSahoy]

I recently had a dealer replace the parts on the Clutch Pack for the PTO on my 2004 TC55DA. Ever since I got it back the tractor has a delay when shifting it into forward or reverse, especially once it is warmed up for 1/2 hour or so. Sometimes it will also come to a complete stop when climbing a hill, even thought the engine is running fine. If it shut the tractor off and start it up the tractor will go. Seems to have something to do with the transmission. I have made adjustments on the brakes, inching pedal, and have changed the hydro. fluid and filter. These did not fix the problem. Could the work that was done on the PTO clutch pack effect the transmission clutch pack? Thanks.
