or does it have to be that specific engine oil ... 20 - 30... it's back to repco for about the 100th time if that's the case.

Somewhere between ATF (~SAE10) through to SAE40.
I'd suggest a google search for a service manual for the box.

REPLY from ROBBO.....
THANKS guys.,.. yes I rang a gear box expert this morning on the north side of brisbane.. and he stated the same and have drained the gear oil.. and put 15 - 40 W engine oil in as instructed....
It for a little while.. grabbed quickly REVERSE gear again....
but only spinning VERY VERY slowly in FWD...
Does loosening // tightening the Nut on the side gear lever / arm, do anything ?? Should it be fully tight or a little backed off..
as I back the nut off/ loosen. The gear arm slips out a few MMs as I push it to FWD or REV gear..
I of course have also tried to move the gear lever with the nut fully tight also... seems to slip more internally when really tight..
Any other options fella than unbolting the prop shaft and taking gear box fully off ???
*** when it did grab reverse... it really grabbed it.. and stayed in gear.... but we tried fwds straight after... no FWD and lost REV motion too.. ???
would like to get out of manly harbour at least this year...
THANKS AGAIN mates.... really nice to have free help right now.. ( disability pension just started.. not happy about that.. )
