I've got a 1990 with 5 speed. I have it on the lift and drained everything. I read elsewhere that the transmission should be over-filled by a quart of so? Is this a good idea. I did shoot an extra qt in there, but can always pull the fill plug to drain it back.
Thanks
Steve

Also it's recommended to use 5w30 syn motor oil.

It's widely considered a good idea. I've always filled to the top PTO bolt.
