GR1600 Transmission fluid strainer

[greenstreak]

Hello, hoping someone can help. I don't seem to have a transmission fluid strainer or drain plug for the UDT. Could I perhaps have an early model without one? I'm assuming I just remove the metal pipe to drain an don't worry about the strainer? Pictures from the manual (showing what it should look like) and what I have below. All the pics I can see online show a strainer.

Discovered this while replacing the fuel lines and cleaning the tank to try and cure some rough running/bogging down that can be relieved by rocking or tilting the tractor to the left.

Cheers

So in case it helps anyone else I just drained the fluid by undoing the solid pipe circled above and letting air in by loosening the filter. Just under 3L came out so all seems to have drained fine. Looks like there is a strainer behind that plate but it didn't want to some out and I didn't want to damage it or score the face so left it in.

Also rough running now sorted, filters didn't cure it so went a couple of steps further, cleaned the tank (washing up liquid and water and a length of chain, then lots of rinsing and drying), also changed the fuel lines and while I was there the fuel pump - all sounds much better now.
