I have access to a lift tonight so I can finally get under the car and change out my tranny fluid my question is. I have a 2000 ZX3 5 speed and want to put redline synthetic in it. Can I put in redline D2 ATF or do I have to go with the D4. I am asking because the local stores carry the D2 but not the D4. I would really like to get rid of the notchiness in the shifter. Thanks to every one in advance.
