BMW ATF1

[Quaser]

Hi

I need to topup my Mrs' Z3 after I changed the rad, and took out the autobox cooling pipes before realizing what they were.

BMW say that it takes ATF1 fluid - whats its equivalent, or am I better off sticking with ATF1 from the dealers?

Also, how do I topup the oil in this car - its a 1999 1.9 auto.

Thanks

Hi there, bit late for a reply, but better that than never.

I suppose that you have dealt with this a while ago, but anyway...

Being a beemer, I would definitely stick with what the dealer advises to use.

If it is equipped with a 5 speed auto, it's best that you entrust that to a Beemer dealer because it might not have a dipstick, so it has to be done from underneath, and it's a messy job if you are not equipped correctly. (been there, done that, got the T shirt)

Topping up auto gearboxes is usually done with a warm engine, so take it out for a spin before you carry it out. The GB oil is considered warm after a 20 mile run or so.
Next, you need to leave the engine running, apply the handbrake, depress the brake pedal and go through every position with the gear selector starting on 'P' and ending there as well, giving it three to five seconds on each slot. This makes the oil circulate through all the internal circuits of the 'box.
With the engine idling, get out and check the level with the dipstick, located in the rear left hand corner of the engine bay, if I remember correctly. Use a clean funnel to top up, being extra careful not to let any dirt in with the new fluid.

When you are satisfied, take it out for a spin again, using all the gears if you can, come home and check the level one last time, just to make sure.
