you have to loosen the rear diff cover plate - 8 (12mm?) bolts - put tranny in 3rd for better access to top right bolt. Gasket usually sticks to tranny and I haven't had to replace one yet for leakage. Would be a good time to clean the filter screen - need to entirely remove rear diff cover plate to do that.

Adding to the tooonns of info/opinions in archives re: fluid choices & specs

GLs / Gear Lubes:

91-94 MYs: Honda MTF (75-80 GL4 dino or semi-synth?) for slightly better shifting; synchro changes & poss shift fork changes in 91, 92? RL arguably might help PG durability (PG upsized in 89, IIRC)

-91 MYs: RL MTL or RL MTL+MT-90 mix or other synth choices

RL MT90= 14cst
RL MTL= 10cst
Amsoil MTF= 9.5cst
Amsoil MTG=14cst
Honda MTF is 11.5

BG SS2; Neo

Quaker State Syncromesh (75W-90 GL-4 dino) seems v. popular in Sweden/Norway and other QSes| may be harder to find if in US; LubroMoly 75W-90

Motor oil: friction modifiers and add pkgs can vary between brands. 10W-40 good visc choice. Castrol GTX dino seems popular in US. Valvoline DuraBlend semi-synth 10W-30/40. Rotella T 5W-40 semi-synth
