I tried uploadinf a video but it wouldn’t let me.

In order to replace the trunnion the hydrostat must be disassembled and there a few things you must know first before disassembly (half length roll pin in trunnion shaft to swash plate, swash plate alignment (install backwards and goes like heck in reverse and slow forward)).

Looking at the picture, it does not look that bad (need to see better picture) possibly just weak springs. Usual issues are slop in linkage, adjustment, and weak springs. I have found replacing the two springs along with placing a flat washer the size of the outer spring on each end of the spring under the spring pin guides will really speed up and increase the reaction of the hydro. Down side to the washers installed is you have to feather the hydro lever on take off or it will take off harsh and immediately. I have mig welded them before although they were in much worse condition than what I see in the picture posted. After new springs/washers installed there should be no free travel of the trunnion in damper plate.
