Changeing The Oil In A R34 M-at Auto Box

[ian]

Been searching the posts, can't find anyone who has changed the oil in an R34 auto box. Does anyone know -

1) How often should we do it (ie I'm not having any problems, but the car has a few K's, should I change it)?

2) I've heard that there is a oil filter in the box as well, is that so?

3) What oil is right for it?

4) Anybody done it and can share their experience - including the filter change (if there is one)?

k i do this for a living. to properly service ur transmission you have to take the sump completely of the car. from memory u dont have to remove the crossmember. yes there is a filter inside the box but its a pain in the ass to remove an its a mesh type filter which means u can just clean it out not replace it. on the sump there is a pan gasket which is recommended u replace cos itl just leak. or if u want to do it quikly theres the possibility ur sump has a plug in the bottom of it. just screw it out and wen u put it bak in put a new copper or aluminium washer on it or itl leak. its recommended u service ur transmision every 20000km or 12 months or if u drive it extremely hard change it sooner if u wana spend the money. oil recommended is a dexron 3 type oil and the filler tube is located drivers side behind the inlet manifold in a pain in the ass spot. hope this helps

Yep - that helps as it means there is no way I'm going to try and do it myself! Do you know anyone in Melb who might be able to do this competently??

Any transmission specialist should be able to do it..It shouldn't be anything scary to them.

I don't like getting my skyline near anyone who isn't used to doing skylines... :-)

Sif go to a transmission specialist. I've done this on other autos on my floor in the garage. It's not hard.

Just about 10-15 bolts holding the sump on. They're all low torque, so easy to undo. Drop the pan, dump the old oil, replace the filter, replace the gasket, replace the pan, fill with oil. Easy as.

I wouldn't bothe rwith the tranny specialist. Any mechanic can do it. I wouldn't pay more than $50 in labour to do it.

The tranny service kit comes with everything you need.

check the manual for the recommended amount of dexIII.

Keas can do it.

I've done it.

Yes it has a sump plug. Yes it has s cleanable mesh filter but it's not hard to remove but you do need to remove the pan/sump which means new gasket.

Also don't forget the torque converter is full of fluid so it's best to flush it which requires a machine that you and I don't have. Seriously, any auto transmission place can do it.

Next best you can do is undo the hose going to the trans cooler and drain from there - engine on in P til the flow stops. You then top up, take it for a drive and repeat. That's close enough to a flush if you ask me.

The tranny service kit usually includes the filter, sump plug gasket and sump pan gasket.

There's no need to get a tranny 'specialist' to use their machine to flush it. Waste of money.

What I do is undo the heater hose too. Then you'll get most of the fluid out.

Fill her up, start it, moev it through the gears, and check the level.

You can't get all the fluid out, btu that doesn't matter. Just do it more often.

e.g. when you do your engine oil, you can't get it all out. But that doesn't matter. The new oil dilutes the dirty stuff.

Just do it more often
