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.

Yes, the linkage is a little loose here and there because of its age and use. It appears your main issue is collapsed springs. Don't pull the rear axle out yet. Pull the tunnel cover and LR tire off then you can get a pair of snap ring pliers through the inspection hole in the frame to remove the snap ring for the damper plate. Then pull the snap ring off for the control cam plate. You can now slide the damper plate over far enough to install new springs and washers. Install 2 new springs from Cub Cadet, place the washers as I instructed you, then compress and slide them all in. Reinstall the snap rings, install tire and adjust the drag on the hydro control lever nut then take her for a spin. I think you will find the springs will repair 90% of the issues you are having! If everything is fine and neutral is right, install the tunnel cover.

Might also want to shim up that damper plate to help eliminate the side to side play. That changes the geometry of the linkage enough to cause issues sometimes. It's a 5/8" ID shaft. I use https://www.mcmaster.com/3088a323 for that job.

Haha that and I wanted to paint the frame. Also had to put a new fender pan on, fix the broken dash, service the transaxle, and now fix the trunnion and driveshaft coupler. I went in head first, I’ve never had one apart lol

While waiting on parts to come in the mail, I’m cleaning the tractor up. Does anyone have any idea what these holes would be for?

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
