ATTS is totally seperate oil fom gearbox.honda-hardy wrote: 1, is the atts oil supplied by the gearbox and cooled by the rad using the standard gearbox oil, this is what i think is correct, or does the gearbox have a separate oil supply to the atts?
It is the ATTS ATF fluid that is cooled by the rad NOT the gearbox oil.
When changing the rad, clamp both ATTS hoses as low/near to the rad as possible to reduce amount of fluid loss.
ATF-D2 minimum but Honda ATF-Z1 would be prefered2 if the atts oil supply is sepparate to the gearbox, what oil do i use?
Gearbox oil level is checked in the same way as all other manual Preludes but you have no need to do this as described in 13, if the oil is supplied by the gearbox then is it a case of removing the upper gearbox filler plug and topping up like a normal gearbox until it just starts to dribble out of the plug hole? this is what i think is correct.
Unless you are fully drainig the whole system all you will need to do is the following - Procedure needs to be done on flat and level ground/ramp4, if the atts has its own separate supply, how do i fill and blead the atts system.?
ATTS has it's own filler and level plug plug on the n/s of the unit itself.
Remove level plug (small 10mm headed bolt) and top up level until dribbles out (slow fill). Refit level and fill plugs.
Road test car to get eveything up to temp being sure to take in some cornering to get the ATTS working and up to temp.
Switch off and recheck level - top up if required.
A full drain of the whole system is a little different but I'll not go into that here s it's too time consuming to type out and I have a workshop full of cars to get done
