Redline doesn't need any additive - it already has it. http://www.redlineoil.com/product.aspx?pid=134&pcid=4

I have a notchy 2nd gear as well, 1st to 2nd gear change frightens me and my car has a very low tolerance level, you have to execute the shifting technique flawlessly in order to have a smooth shift.
I just drove today my friend's M3, that car is just a dream come true when it comes to shifting, i wish there would be someone dedicated enough to figure out if there's something wrong with the transmission or clutching mechanism or if it's just the way it was designed. |

I am aware of that, i wasn't comparing the 2 transmissions as if they are the same, i'm comparing from an M car to another M car in gear change feel.
That's why I asked if there was someone dedicated enough to discover why our transmission behaves differently and if this was a design flaw that can remedied somehow or just how the car was intended. |

Has anyone ever tried fitting an e46 M3 transmission in the Z4M?
what would be needed? maybe a shorting drivetrain axle in order to complement the longer transmission from the e46 M3 ? has anyone opened the ZF type H gearbox from the Z4M to make notes on what could be wrong not allowing us to be careless when shifting ? |

the getrag box in our cars is strong, shifts well and is a solid unit... the z4m and 3.0si is how old now and how many have failed world wide??? hell ive read about 1 i think..... and that was a syncro problem..... Weve strapped blowers to the these cars, turbos pushing 650rwhp, and still the gearbox takes the power...... my gear change has always been butter smooth, i get no crunching and i like the feel, its due a fluid change now and im certain it'll restore my usual buttery bmw change back to how i like it... AFAIK the 1m uses the same gearbox....

Well then i must change my transmission fluid once the drain plugs gets here.
I don't have buttery smooth shifting unless i perfect the shifting technique. shifting gears in the M3 is hella a lot more fun though :P |

I went with OEM in the diff (always forget how nice and smelly diff fluid is) and Redline MT-90 in the tranny.
For stubby sockets I picked up some from ZDMAK tools on ebay. Good pricing, decent quality and the 8mm for the tranny is ...8mm. |

What is your impression on Redline MT-90? It seem to shift better compare to OE tranny fluid. Dealer replaced my Redline during insp II and my shifting seems harder when car is cold. It also whine during decel.

What method/pump are you guys using to do the refill? I just got the ZDMAK stubby extensions, and I'm trying to figure out a good way to do the refill with the limited space I have while working in the garage under the care w/o a lift.

For the diff, the OEM bottles have a pull out spout. I used a short piece of tubing on the spout and could fit the bottle in the open space around the diff. tip down and squeezed. For the tranny I used a fluid pump like this right in the Redline bottle. (http://www.ebay.com/itm/WILMAR-QUART...ccab6d&vxp=mtr |

I only have about 10 miles on the new fluids so jury is still out. Seems to shift a little smoother than OEM, but only very slightly and I think I've got a tranny that seems less notchy than others. The fluid hasn't been colder than 55 degrees (warming up here in the Northeast, woohoo!) so that will have to wait. I'll keep my ear out for the whining (hope I can hear it over my daughter's!)

While it's on my mind, when I changed the diff fluid I had more left over then I thought I would (about 150 ml out of 500ml in the last bottle). I made sure the car was level by measuring the floor to wheel arch distance, if anything it was even a little higher on the right side. I definitely couldn't have put in more.
Have people had similar experiences? |
