Shifting Into First Not Possible...

Hard to do on my G37S

Being that 1st gear is your main gear because its the one thats always being used out from a complete stop, theres no good reason to subject the transmission to this type of downshifts, But again it's yours to do what you want with, it's your transmission, but if you start Posting with I'm having Transmission problems or my 1st gear took a dump will at least know why....

Cjanik · 03-15-2010, 07:48 AM

yes there is "sort of" a physical limitation, to avoid from shifting into 1st gear while you have second on redline and attempting to go into 3rd.

once you slow down enough, then the limitation will go away and you can slip it into 1st, but this is so slow that there's almost no reason to do so. if your already moving but want a faster start in 2nd, hold the clutch in and feather it out while reving the RPM high.

never never never try to force the car into any gear. if it wont go smooth, then you can possibly bend/damage something by force.

Could be a lockout, similar to reverse where the transmission will lock out the gate while moving to avoid an accident in addition to blowing up your transmission. Otherwise, take it to the dealer because if there is not lockout your car should be able to be shifted into 1st. Of course, as other said, it's not something you'd want to do unless you are going very slow.

I don't see the use for 1st gear while moving.

and it being hard to push into first gear is normal as far as I know

Clio couldn't do it.
megane coupe couldn't do it
megane CC
master.

no single car I have driven shifts easily into first gear while moving.

sure I can force it. but if I DARE do that with the master it starts making noises.

the bad breaking cogs noise.

I am sure that it is on purpose.

I mean going from 2nd to first from 3000 RPM would result in near redline revs.

not good for the transmission

true, i dont see myself downshifting into 1st from 3K in 2nd in my z....but in my honda fit, different story. i need to get my vtack dosage every time.

prichardson · 03-15-2010, 04:01 PM

Looking at the gear ratios, 3000 RPM means you're going about 28 MPH. Downshifting to first at that speed means your RMPs need to jump to just a bit under 5000 RPM. I echo what most people are saying here - that's a tall order for your syncomesh.

Jeffblue · 03-15-2010, 05:10 PM

I haven't gotten my Z yet, I have never owned my own MT car, only driven those of friends, and i know never to shift into first while moving at any sort of significant speed. definitely not if i'm at 3k in 2nd.

Vegasboricua · 03-15-2010, 05:18 PM

Totally bad idea to shift into 1st gear...especially at that speed. The 2nd gear is very good. I pretty much been in a dead stop in second and never had a problem. I usually dont shift into first unless im at a light. At stop signs I keep it at 2nd because ill still be rolling very lightly

spitfire9200 · 03-15-2010, 05:22 PM

Yeah I have never, ever heard of anyone shifting from 2nd to 1st at 3k RPMs.

I only go into first if i'm going about 3 mph or stopped. 2nd gear in this car has enough torque to keep the car going without stalling until you hit like 1 mph

tonybui · 03-15-2010, 06:06 PM

I was once going like a little bit over 5 mph and i couldn't get into 1st. I felt something pushed it out and I didn't force it since

wishihadnav · 03-15-2010, 07:09 PM

lol..its possible and the dealors gonna tell you the same thing all of us did.. dont do it.

I mean for a 40k car, shouldn't it have a smooth shift? Has anyone else have this experience? It is really frustrating me.

I am going to take it to the dealer very soon. I just hit 1k, so I need my first oil change anyway.

Why are you downshifting into first? That's insane.
