Auto' Box - Fluid drain/change.

[Steve W]

Just read old threads [ Phil Wall, Mycroft etc. ]

 

Who's done the 'Partial Change' of ATF fluid on their Soop ?

 

Has the box got a drain PLUG, or did you have to remove/refit

 

the sump-pan ?

 

I'm gonna get some of the Type-IV ATF (not knowing what's in it

 

at present) and don't want to fart about with the cooling pipes.

 

I'd rather do a couple/few partial changes (I realise only a BIT

 

gets changed by draining the sump.

 

IF it's got a plug - piece of cake/pi** etc.

 

IF sump - did you need new gasket ? ?

steve, there is a drain plug on the bottom of the transmission sump. so its piss.

 

the sump doesnt have a gasket as such, its one of them gasket in a tube things.

 

im just about to do a full flush on mine, including a clean strainer. just for the record u dont need to buy a new strainer (quite expensive), it can be cleaned by soaking it in brake disc cleaner then preassure washing it.

Cheers Mr. EYE,

 

I'm not sure if I'll take the sump down - but if it's got a plug

I'll definitely treat it to a couple of 'partials'.

hmm i'd go for the full drain if filling with type IV (if you've got £125 spare for the fluid). Although the NEW type IV (make sure you get the new stuff part number 08886-81015) is compatible with all fluids, they do say you will only feel the difference when at least 75% of the fluid is the new stuff. Doing a sump change will do next to nothing.

 

If your car is now a few years old it'd be adviseable to do a complete change anyway, as it prob hasnt been done for a while.

 

I paid £80 i think for a very reputable gearbox specialist to drop the sump, drain everything inc toque converter, new gasket and a general service. All in all i think it was £200 well spent and well worth it for peace of mind. The gearbox is just as complicated as the engine, and should be treated as such.
