Title: Auto box oil change
Post by: omega3000 on 31 December 2011, 20:19:58
Hi all , ive been reading the threads on how to change the auto gearbox fluid and see that the car needs to be running while this job is done ... while draining the old oil out im supprised it doesnt cause any dammage with no fluid in especially when the car is still running while you lower the car to drain the excess  ??? Or have i missed something about turning the car off during the process .
Just checking as ill be doing this pretty soon  :y

Thanks  :y

Engine is off whilst sumps are dropped and old oil is drained and filters changed etc.

Engine is still off when sumps replaced.

Engine is still off when oil is introduced into filling hole until oil drips out filling hole.

Engine is now started and gearbox pumps oil around the system, subsequently lowering the oil level in the casing.

Oil level is now topped up whilst engine still running (and car on a level keel - most important) until oil weeps out filling hole, then plug is inserted into the filling hole.

If filling plug is removed whilst engine is off, expect oil to pour out and up your arm.

I dont think im going to be able to do this without the aid of a proper 4/2 post lift seeing as the car has to be level , crawling under the car is a no no with engine running me thinks .

That's where you need an extension of some sort. 2 short planks would be good enough  ;) ;) ;) ;) but I was able to make these at work.  :y

Personally, I would use the ramps on the front by means of a piece of wood or similar to reduce the approach angle of the front skirt of the bumper to avoid impact and have the rear wheels on axle stands.

That removes ANY possibility of inadvertant starting of the engine and running it through the gears and then forgetting the car is 18" up in the air and the rear wheels in contact with the ramps.....   ::)   :o

My reasoning for reversing up the ramps was that the back wheels were locked/braked while I lift the front. If done the other way, the front wheels are free to turn while you lift the back .........  ??? ??? ??? No right or wrong I suppose.

Fair comment.   :y

If any doubt, or suspicion of raising one rear corner too high so the other becomes unbraked, you could use a ratchet strap around a front wheel onto the ramp keeping the car in place.

Or just raise the rear corners a bit at a time until both off the floor....  :)

Once the car is up on the ramps i guess its a case of jacking up each corner bit by bit till its level ....too much of a balance to jack the whole front up in the middle , dont think my jack will take full weight of the mig  ???

I am lucky enough to have a sloping driveway.  So I made up a pair of ramps with the same gradient so the car is left horizontal with just enough room to work underneath.  They run the full length of the car, made from railway sleepers and scaffold board - over engineered but safe and simple to use.  I'll post a pic next time I use them.

We moved from Scotland when the kids were young.  I remember one of them coming home from school confused by the local dialect and asking me "What's an armpit?".   ;D

That's what airing cupboards are for.  ;) Firing up the arc welder at night dips the house lights though and annoys swmbo.  ;D ;D

I've used my mates big high lift trolley jacks before and managed to get my car on four ramps. That really confused the neighbours.  ;D ;D ::)

This can be done without lifting the complete car.  I cannot claim originality for this, I read it on here some time ago.  To check the auto box level, raise one side of the car and remove filler plug and add oil.  Place drip tray under and lower car with engine running.  When oil stops dripping out, raise car with engine still running and refit filler plug.  Obviously use axle stands before going under car and very securely chock the two wheels remaining on the ground.

NEVER use axle stands on a sloping surface!!

You've got to hand it to Broocie with that degree of reasoning Andy - although I have to say there's no 'arm in your own assertions.

Another way  :) , that sounds easier than raising the whole car esp as i have a slope on the drive ...not too much of a slope but i guess its enough to make it dangerous . Thanks for the advice  :y
