QLD: A big shout for Boxstop at Slacks Creek for auto trans service.

They offer competant advice and don't rip you off with automagical BS. My brother went in there with a slipping trans in his EL and $65 later left with a new gearbox mount and a topped up trans fluid. He's very happy. Boxstop are honest.
Cheers!
