In the photo above, which shaft of gears has the gears firmly locked in place, and which one allows the gears to rotate on bushings (assuming typical transmission construction)? If the lower shaft is the fixed or solid piece (with gears cut into a solid shaft), would the importance of it now being submerged in oil be as important as the upper shaft gears floating on bushings, which is now in the "dry"? On the T-5 trannys that I've built, this was the case with the counter gear in the oil, and the mainshaft (with floating gears) that drove the output shaft was in the "dry".
Both shafts have gears spinning on them, 1st/2nd on the top shaft of above pic to RH & 3rd/4th on lower to left, attached pic & dwg might help you get your heads around the issue. This is more critical than aiming squirters @ the gear teeth & getting oil onto those rollers/bushes or even steel to steel in some types.
