At the 160,000 km service on my automatic 2004 Toyota Prado diesel I asked if the automatic fluid needed changing and was told no. The automatic transmission has never been serviced, and I get conflicting advice on this matter. Some say that it is sealed, has no dipstick and never needs servicing, others say it should be checked about 200,000 km and others say that the fluid should be replaced at 160,000 km if it has been driven under harsh conditions. What do you say?
The gearbox is sealed in production and it's not meant to be serviced for "life", but what "life" means is anybody's guess. Oil is the lifeblood of an auto transmission and Andrew of AW Automatics is of the old school, which advocates changing the oil every 20,000 km, particularly if the car is being used for towing. On that basis you would be well advised to have it changed.
