I am about to do the pleasant task of replacing ATF.
I have a few ?'s :-
1) I will be using liquid gaskets on the sumps - is it best to use the old gasket & put the sealant on the gaskets/flanges or is it better to dispense with old gaskets and just use the sealant on the flanges (both or 1)?
2) According to the haynes manual capacities for the auto gearbox are 8.4 litres (from dry) and 4.4 litres (after removing main sump) so does that mean I can only get 4 litres into the box and how do I get the rest out?
3) This is a daft ? but it has to be asked - has anyone tried to fill the sumps up with oil prior to re-fitting or would you end up swimming in a sea of ATF - never taken the sump off of anything so don't know how practical/silly this is!
Thanking you in anticipation of some life-saving replies. :y
-
1) Discard gasket
2) A load stays in TC and in cooler. To remove from cooler, use a byclce pump on pipes to cooler ;)
3) Much easier to refit empty
-
use a hose through to the engine bay and a funnel to refil or even better get hold of a cheap garden sprayer and pump it in. :y
As The Boy says a lot of the fluid will stay in the Torque Convertor so difficult to fully change all the fluid :-/
-
You'll need more like 7 Litres if you remove both sumps.
Also you are unlikely to get the gasket off in one piece so it will need scrapping off. (a pleasant job as ATF drips on your head... not)

You really should change the filter too, plus new sump gaskets.
Torque convertor and cooler also need to be flushed/drained to remove all the old ATF.
Hell of a 'pong' from old ATF, so drink some milk before you start the job!

According to Haynes you dont need to - just put it in a bath of solvent (whatever that is - hydrochloric acid?)
Liquid gaskets should do the job just as well at about 1/10 of the price.

Yes I plan to use cheap garden sprayer - tried using funnel & tube but when I poured oil in funnel it just stayed there - probably due to not enough pressure to force oil down & up the bend into filler hole.

Could you please explain bit more? Which pipe do you connect pump to and do you only use air pressure or pour oil into the pump?
