"As many are not willing to accept nor embrace modern technology in performance transmissions, they will never have the pleasure of feeling what the e46 M3 is capable of under the most extreme driving conditions. Any enthusiast can drive a manual, only few have mastered the precision it takes to drive this transmission well at both fast and slow driving speeds. This is a statement you cant honestly comprehend until you've put significant time behind the wheel of an SMG2 yourself." -S54SMG2
SMG2 Shift Speed: As I read on and on about the apparent hate for the SMG2 transmission as well as claims of faster shifting in a manual I post this tested information showing the smg2 at WOT/ S6/ DSC off/ 3-4 gear shift.
I personally love driving manual and miss it too, but this transmission is so much fun I'm not sure I understand any hate for it. Preference I can understand, but hate?!
e46 M3 2005 SMG2 No Power Mods OEM Euro Flash CSL trans flash No DME CSL parameters had been done yet (not as if that really makes a difference in comparison)
I invite anyone to post their data with a 6mt for comparison.
SMG2 Maintenance: What do you do to maintain your SMG2? I assume most will answer nothing, even though they want to say otherwise The truth is there is very little to maintain although the few things that do need attention most often does not get the attention it should.
1.Keep your MAF sensor clean.
2.Have you changed your SMG fluid? Why not? -make a habit of turkey basting fluid in the smg reservoir. Fresh additives are needed to protect. Simple as that.
3.Have you replaced the compression springs? Were they broken or just worn out?
4.How often do you run an SMG adaptation with INPA or GT1? (this is NOT the paddle soft reset) -this is needed to keep your transmission calibrated to function properly. I suggest doing it yearly if not every six months.
5.Anyone upgrade their rear diff bolts? -I had not expected such a change
*I feel a transmission cooler would be very beneficial for all SMG's as well. This will allow the overall trans housing to maintain cooler temperatures, preventing excessive heat damage to the actuator and gear identification switch.

TESTED- CHF 11S Hydraulic Fluid:
It would seem as though the CHF 11S hydraulic fluid is truly a quality oil. It is suggested to be a lifetime oil, although Pentosin representatives themselves told me the fluid does have a 5 year shelf life, 7 max in the metal can they supply the oil in, but possibly less than 5 if stored in plastic. As the test was deemed somewhat inconclusive as there are not many samples to compare it to I would still suggest replacing some fluid from the reservoir yearly as preventative maintenance.
As seen in the pump rebuild video below, it seems the engine heat is wearing out the electric components first.

some awesome info here and very on point with my personal experiences over the years. I have contacted Marco for a new pump motor and will have to do a rebuild on an old pump and try it on my car. my original pump is just fine.
