Ok. I got the fan shrouding on. It helped heating issue. I am not getting any wind blowing into engine area. All air is pushing out through the radiator grill.
I worked tractor at high engine rpm for about 20 min. In that time the temperature moved from 160F to 220F. Usually by this time water would be pushing out the radiator cap. It has not done that since the shroud.
I left tractor just above idle for about 15 min and it dropped to 200F.
I am not sure what the operating temp is for this engine. I think that is hot, however it is an improvement.
Also went fixing miscellaneous leakes around engine and made my way to the transmission valve body above the transmission where the speed selector hoses are connected.
I noticed a small leak from port that was blanked. I plugged the port completely with correct fitting.
I then went to test tractor to see if this leak may have contributed to my original trans issues and noticed that I lost all my reverse movement in both high and low range in both 1 and 2 positions. I removed plug completely and regained reverse. Baffled by this I finger tightened plug and noticed reverse engaged but after a couple seconds.
It seems as though the more fluid allowed to escape from this port. The fast reverse is engaged. If I plug complete there is no reverse.
Other than this new trans issue everything seems to be working well for what I need tractor for.
