1990s 520H Transmission Swap

Hey guys,I have a dilemma I need some help with. I have a 1969 GT 14 that I replaced the transmission and pump on. For about 2 weeks afterward everything worked great, but while mowing at a pretty good pace I noticed a shudder and the tractor slowed a little but not bad. The more I rode it the slower it got until it barely moves. What stumps me is the hydraulics are still very strong,as in I can back the 3 point under the bumper of my truck and if you lift the arms all the way up the front wheels of the tractor will clear the ground. Have checked the tow valve and checked the internal filter,but no luck. I have also checked and replaced the forward and reverse bypass springs and the lever is moving the cam to full travel, forward and reverse. Any help would be appreciated.

Now that we are finding more uses for the 1990 520H with a KwikWay loader I am experiencing some power loss in the hydro after about a half hour to 45 minutes??????
Selling my trusty WH520H. ~880 hours (currently used for moving snow when needed so hours may rise) very solid machine, strong and hardworking. 20HP Onan, hydro transmission and hydraulic lift. Has Matt's foot-pedal conversion for forward/reverse. Included in the sale is a tall-chute snow blower and 60" mowing deck. The blower is in excellent condition and is on the tractor currently. The mowing deck has been a workhorse over the years. No holes but could use some TLC, probably needs new spindles at some point and could use a couple spots touched up with welder also does NOT have any pulley covers/protectors (see photo). Tractor has been an incredible tool, very solid and dependable and I'm certainly going to miss her when she's gone.
Recent maintenance: replaced the plugs this summer, fluids as needed (hydro has about 100 hours on fluid/filter; oil was done in the spring and has about 25 hours on it). Battery is about 3 years old as are the tires, Terra Trac tires on the rear and turfs on the front. The seat (with arm rests) isn't in great shape. I've got a cover for the seat, never used. It's never really bothered me but new seat cover is included in sale as are 4 hub caps, chains for the rear tires, and some misc spare parts (see photos).
I've owed this machine about 8 year and put ~350 hours on her. She's not a show piece but could be restored. Sheet metal is generally in shape, no rust however the hood does have a couple dings in it.
I'm only selling because I'm trying to help my son get a small lawn care business started and looking to move to a zero-turn. The 60" deck is too large for our trailer, the mowing deck lacks pulley safety shields, and we'd like something that mows faster. My only complaint with this machine is the top-speed (which isn't great when comparing to today's machines) otherwise she's a beast. They don't make them like this anymore.
Nice solid clean 60" deck for 520H Model # C560SC04 $500 OBO

I have a new-to me 1990 520 with a KwikWay loader. Have been going thu piece by piece and checking for anything that needs attention. Found some wobble in the rear hubs (both sides) the key ways on both the axles and hubs shoe some pretty heavy wear. Was wondering if you have used the hub repair kits that A-Z sells and any comments good or bad?
