Transmission out of car
Restoring 85 GSL-SE. Have engine and transmission out of car. Is there anything that would be a good ideal to look at or replace in the trans while it is out.

While it's out - if you're after reliability - crack the tranny from the engine which is much easier with it out of the car than in, and have a look at the following;
1) check condition of Pilot Bearing - run your finger inside the bearing on the end of the Eccentric Shaft on the engine and see if it rolls smoothly - if nothing else, relube it and put a new rubber seal on it. This bearing is the source of a lot of pain down the road when it grenades in there and causes your transmission to drag or lock up...
2) Clutch Pressure Plate and Disk - I would just replace them both if it were me, and you have the money. Might as well do it while it's out and know you have a new clutch in there. If nothing else, remove the PP from the flywheen and gently sand all surfaces on the flywheel and PP to get good traction. Also, check the clutch disk to make sure it's not getting worn down to the rivits - again, maybe better just to put a new one it and be done with it.
3) Throw-out Bearing - the TOB is often the source of a 'whirr' coming from the shifter inside the car, and at $15 or so, is cheap insurance on the clutch functioning smoothly. If it rolls smoothly and spins freely (and quietly), you may be alright to leave it in.
4) Transmission front cover and gasket - this cover is where the TOB slides when you operate the clutch. Oftentimes, the TOB will wear grooves in the front cover shaft that you can feel through the clutch pedal. Replacing the front cover gives you a fresh, smooth surface and cleans up pedal feel and action. Also, the front cover gaskets can erode allowing transmission fluid to leak into the tranny bell housing, which is hard to find until you've lost a lot of fluid and cooked your transmission. And, while we're at it,...
5) Tranny Fluid - Royal Purple, or your favorite flavor will ensure fresh, clean oil is lubing your gears and synchros. Will dramatically improve the shifter feel and lead to longer tranny life. If you don't do anything else above, do this.
6) Check your flywheel gear teeth for chips/missing teeth - if you have any missing teeth or heavily chipped teeth, it could cause your starter to spin freely or grind up the starter pinion gear. While it's a pain to remove the flywheel nut, it could save you repairs after the engine/tranny is back in the car.
Since you have everything out and easily accessible, it's worth doing these changes to avoid having to live under the car in a few months due to a bad clutch PP or disk goes out. Good luck on your SE project,
