Holy dead thread revival batman!
As a note, I ran the manufacturer recommended fluid and have had no Ill Effects. I was having some stiff shifting issues before the rebuild when cold, but that must have just been due to the synchro's which were on their way out.

85-140 + lucas oil stabilizer. Its thicker to help quite the trans and tcase down plus doesnt leak as easily and or let in water as well, I had an L45 and she was a GRowler put in 85-140 much quieter, then aded lucas even quieter and shifter smoother, no hard shifting ITS a toyota 4x4 trans for crying out loud not a maseratti these guys can use some thicker lube to help with the slack caused by abuse and high mileage. i also use it in my w56 now and even after my 4.7 install. the tcase even whines waay less with 85-140 and lucas now takes around 5-6 hours of solid wheeling to start whining at all.

It apparently corrodes yellow metals, like your synchros. Use the the gl-4 or some high grade stuff. Everyone will have their own opinion of course, but basic gl-4 cheap stuff works fine. I have been using Amsoil synthetic 75-90 gl-4, it has worked flawlessly from 0 deg to 110 deg/f. Its good stuff but pricey.
