6sp manual owners

bmwm3redblack · 07-25-2011, 07:35 AM

i wonder why it is so hard to shift from 1 to 2 if you are on high rpm. It never hapens with 3-4 ,4-5,5-6 shifts.
May be smth wrong with my synchrons? or whatever?
I am afraid for the tranny,cause my car is stock now,and in a few days i get my cobb ap,defenitely more stress after the tune installed,so i wanna fix the problem now.

Please help?

ApexM3 · 07-25-2011, 08:45 AM

Sounds like you should take it to your dealer. I have no issues shifting from 1st - 2nd with my AWD 6mt.

pdav · 07-25-2011, 04:17 PM

+1 on hard shift from 1st to 2nd

bmwm3redblack · 07-25-2011, 05:40 PM

So what is it???

gaberoll · 07-25-2011, 07:37 PM

what do you mean by "hard to shift?"

does it require a lot of physical effort or is it just difficult to shift smoothly?

redlinedbimmer · 07-25-2011, 08:56 PM

IMO its harder to shift if you shift too slowly.

Malapropism · 07-25-2011, 09:23 PM

I would say that my 1st to 2nd shift at high rpm has substantial resistance, more so than the other gears, but I wouldn't classify it as overly difficult or problematic.

+100500 have same problem

Toker335i · 07-28-2011, 02:58 PM

CDV wont fix hard shifting going from 1-2,

its normal. lots of 6mt exp. this, especially BMWs.

Volasko · 07-28-2011, 09:04 PM

1 - 2 shift is particularly difficult to do smoothly, under hard acceleration runs. I find at least for my car the RPM's don't drop fast enough so I am always waiting a little longer than usual when trying to accelerate quickly... yet smoothly (matching the right RPM when disengaging the clutch)

E36graduate · 07-29-2011, 02:50 AM

you gotta time it just right for it to work smoothly......every bmw i have owned, e36, 2x e46 and this one does it too......however I havent driven your car so I don't really know.

skys the limit · 08-02-2011, 05:24 PM

Always funny to hear ppl try to give advice from just reading things on another thread. Cdv won't fix hard shift 1st to 2nd

the_doctor · 08-03-2011, 01:06 AM

I'm not a mechanic, but I think you just need to shift it at the "sweet spot". I.e. when you go into 2nd gear at a certain speed, there's a certain rpm level that will allow the gear shift to just "slip" into gear without much effort. From a personal experience, if I'm revving high in 1st gear and trying to go into 2nd, I'd have to wait perhaps 0.25 or 0.5 of a second after I depress my clutch and going through neutral, before it "slides" easily into 2nd.

To find out what the "sweet spot" feels like, you can do this on an empty road / parking lot: at a low speed (say at 10 km/h), go into neutral with the clutch depressed (no gas), try shifting into 1st gear without much effort. The gear shift will eventually "slip" into gear as your car slows down - it will feel almost effortless. Same feeling really as compared to shifting with double-declutching. The gear shift will "slip" into the desired gear if the revs are matched correctly.

I hope this makes sense.

Chrisred · 08-03-2011, 11:42 AM

Guess we have to find the sweet spot on WOT. I find when I hit around 6500 rpm it gets harder. In gonna do a comparison at different rpm within 6000 to 6600rpm. This sucks cause it delays us in 1/4 mile. It takes about a second to fully change gear with all that notchy-ness

CJ421 · 08-03-2011, 12:10 PM

There's a big gap in the gear ratios between 1>2, so you just have to be patient and let the revs fall when shifting.

I find when I shift out of 1st at 3.5-4kRPM, the revs fall predictably and I can engage 2nd with little effort and not much waiting in between. If I short shift it at 2.5-3k, the revs don't fall right and I get a push forward.

The CDV mod won't help the gear ratio gap but it sure does smooth out shifting in general. Well worth doing.

+1

If I shift before tach goes below 2K rpm, the shift seems a lot smoother. If I shift above 3.5-4K rpm and don't depress the accelerator until shifted and clutch released and above 2K rpm, it is very smooth.

CobraMarty · 08-07-2011, 06:56 PM

Same for me. Tomorrow mine is going in for UUC short shifter and Redline trans fluid. Hopefully this will make a big difference.

Nah it won't change anything. Been there done that. But I have xi. So maybe its rougher.

redlinedbimmer · 08-08-2011, 08:29 AM

zhp knob has made the biggest difference for me

irfan · 08-09-2011, 05:07 PM

xdrive here... nothing unusual about the 1-2 shift for me.
