gearbox service 2.8 sport

Gearbox Advice.

Ive got a 2000 2.8 Sport FWD with 5 speed tippy box.I got the transmmission fluid changed recently but was wondering whether theres anything else that constitutes a "service" on these boxes as the extensive FSH only mentions a fluid chage at 50K ...and its now done the thick end of 170K ..there are no problems but if anything needs routine maintenance then i feel I should get it done.

cheers

Simon
