Trans Fluid Change

[BlackSapphireZ]

THIS DIY IS FOR 2003 Z4 2.5i MANUAL
do this when the car is fairly warm but not burning hot as you will be working near the exhaust. and again, dont' sue me if you make a mistake..and if you are not mechanically inclined, bring it to me i charge a lot

tools required
1)17mm wrench
2)jack
3) FOUR jack stands
4)2 quarts of Redline ATF D4 fluids yes it's an ATF for a Manual car
5)Hand Pump

My way of jacking up all four tires safely.
1)jack driver side only, put the jackstand under the lower control arm.
2)do the same on the passengerside
3)go to the rear, look at the center where the two bars come together and bolts on. Jack from there to a position and place jackstands under the factory jack location on the sides


1)get the car in the air. all 4 tires off, and in somewhat of a leveled position.


2)locate the tranny FILL bolt on the side, unbolt first!!! and then place a catch can under the DRAIN bolt, and unbolt. it will shoot out


3)when finished draining, tighten drain bolt and proceed to fill the trans with Redline ATF D4 fluid using a hand pump


4)as you start seeing the fluid ooze out of the fill hole, tighten FILL bolt

5) take the car down in a safe manner, use a common sense and you are done!
