Transmission pressure light!

[Joe McLaughlin]

Hi everyone.
Another week another issue!

Ford 7740 sle pre qaud mod.
Transmission pressure light comes on when I use the loader, drive forward (sometimes reveals) it's usually dimly and pretty random but usually will come on at some point when I drive.

Also the tractor feels laboured when taking of or on full lock of the steering.

The loader power line is plumbed into the rear spool power line and return is plumbed to the spool return line. There was blanked off ports already fitted (maybe from a previous loader, 2nd spools or front linkage?)
LS is plumbed into the load sensing line.

Would a restricted return cause this?
.the loader is slow to drop aswell.


Any help would be great.
