Oil Pressure ?

As to the shifting try double clutching or rev matching to slip her in. I usally never use the clutch going into 1st gear from 2nd or 3rd. I just slow down plenty and find the sweet spot to slip it in.

well. alot of old subarus, over like 70k miles, dont like to go into frist untill youare almost stopped. its because the first gear is so short, and the syncros are going bad.
You'll have to pardon my ignorance... I know as much about transmissions as I do about the internal workings of my computer's processor... yeah, I get the major concepts down, but don't ask me any details :-\
I've got the same problem in my '92 Loyale... intermittently goes into first pretty hard, and reverse has been grinding every now and then, if I'm not careful. Worn synchro's? I've never heard of anybody replacing/repairing synchro's before, so I'm assuming it's an integral part of the transmission, and I might be better off swapping the tranny first.

if shifting into first while rolling, it would help to rev it up a little to match rpm

In my owners manual it states that if your car is sitting the oil pressure gauge may drop.....and.....not to be alarmed. I have found if I give it a little gas the gauge pops right back where it should be.
Don't know if any of this helps,

if it goes to 15 or 20 at idle, sounds ok to me.
i have seen 45psi readings slowlt tricle down to almost 0 at idle. at least you have pressure at idle.
ma want to do the pump seal as precautionary, but the pump sounds like its ok to me. i personally wouldnt worry about it

1) Change the oil to Castrol 20/w 50 GTX
2) Change the tranny oil to Redline 75/90 NS
Redline does wonders for "balky" shifters -first gear esp.
Castrol is the best I've found for our engines, 20w/50 works great, a splash (read 6 oz. or so) of Marvels Mystery Oil is also a help.
If it is still low enough to bother you, I would get a new sender unit. (easy to reach right beside the oil filter) I have had several that the gauge was fine and the sender went a little south. They also can begin to leak at your mileage. They go for about 20 bucks on line. Just make sure you get a sender unit not a switch (for idiot lighted cars) unit
Hope this helps

I was told that the gears across from each other share syncros and shifting into the higher gear helps spin them up.
Works for FERTHER!

Geez, I hope so... It's gettin' embarrassing stopping down at the parking lot quickly after noticing somebody beginning to pull out, and either grinding the gears or having to wait several seconds before I can reverse
Thanks for the tip

I did a oil pump and front crank seal last weekend to stop an oil leak (crank seal was hard as a rock and loose), in the process of trying to remove the pressure sender from the oil pump I twisted the cover just a bit (should have removed the sender while the pump was on the engine, more leverage). Since then my gauge would periodically drop to near 0, with no change in sound from the engine. So last night, while doing a oil change I decided to temporarily tee in a mechanical gauge I had, just to check things out, at the time a noticed just a bit of oil seeping from the screw terminal on the sender (problem found). The dash gauge read near 0 most of the way into work this morning but the mechanical one held a steady 38lb or so. I’d bet yours is a bad sender, try an oil change too, maybe just really old oil. NAPA said $32 for the sender, a little steep, but much better than a bad pump.
BTW, my manual said the oil pressure spec for the EA82 is 43lb @ 5000rpm, so apparently the EA82 is a fairly low pressure engine.

and its really easy to rock a mt from 1st to reverse in a mid/snow hole to get things going, if your timing is right

My 87 does the same thing you discribe. The problem is the third gear syncro. When down shifting to 3rd, if I double clutch... no grind.
You may know this trick (double clutch), but here goes. From 4th quickly clutch and shift to neutral. Let the clutch out with the shifter in neutral and give the throttle a quick blip (should raise the rpm approx 800-1000 rpm from where you were when in 4th). Now clutch and shift from neutral into third.
With practice, done correctly and smoothly, it's two quick pumps of the clutch pedal with a blip of the throttle between and you get both the input and output shafts of the transmission spinning approx the same rpm and the gears will mesh w/o a grind.
Works for any downshift where you grind.
Try it you'll like it!

And for sure, double de-clutch it when you want first while still moving. 90% of my shifts are double de-clutched, once you get into the groove it becomes very satisfying. Left side of my right foot rests on the brake, the right side taps the gas on the way through neutral....ahhhhh!
You can also use this to shift upward if you want to skip a gear. If I go from 2 to 4 I will lift the clutch pedal (no throttle) on the way past neutral to slow the gearbox internals for a smooth shift.

That might just explain why it won't go from fifth to reverse. Ya know, it makes sense...
