Does Auto trans fluid need to be changed in 04 corolla?

[joca]

Hi all I have another question I have an 04 corolla wagon with 155000kms on the clock looking at its service history cant see the trans fluid ever being changed on the dipstick I think I read it doesn't need to be changed in normal driving conditions or something like that. The colour of the trans fluid doesnt look to bad but I am still thinking of changing it what do other owners think. I know you are meant to use Toyota trans fluid but I will use Castrol transmax for Japanese cars I actually rang Castrol up they assured me it is compatable with Toyota fluid. Also I have heard if you bring it to Toyota they just undo the Trans sump plug which only removes 1/2 the fluid I want to drop the pan and also pump fresh fluid through the convertor by undoing the cooler line and draining it while running the engine. What do you guys think is this overkill or should I just leave it ? Car hasn't got a towbar and was owned by an older lady and shifts fine

I've got a 2005 model and it has never had the transmission fluid changed....As per Users Manual...80,000Ks on the clock.
