Trouble downshifting to 1st

edub370 · 02-23-2013, 03:27 PM

Guys.... It's called first gear lockout. Many cars, ecoboxes included, that don't let u downshift to first until a certain (and very low) mph. And u should never be shifting into first while rolling anyways

. After 10mph, 2nd gear has all the power u would ever need. Only shift into first at a complete stop.

I'm guessing what's happening, is you're trying to get ahead of yourself and throw it into first before fully stopped. Which combined with a car with a super finicky mt (i.e. 370z) then u will have problems. As stated a bunch of times before in this forum, u cannot rush or "force" this trans to do anything.

There is nothing wrong with the mt in a 370Z for those that know how to use it. I'm in that category with many others in here. I agree with you that you will have a problem trying to down shift into first above a certain speed. I like to do this though in my vette and Z to lock up the rear wheels momentarily. But that's me and it's no worse than doing a burnout when it comes to wear and tear on the drivetrain.

Dude why are u doing that?? Why do u think car manufacturers make transmissions that don't allow that? just cuz its fun to do? If u shift into first at anything other than stop, u are driving a manual wrong.

Listen, i love the 370. Clearly, i bought one. but I'm also not delusional. If u think this MT couldn't use a little work (a corvette isn't exactly the industry standard in tranismissions either) then u are drinking the kool-aid a little too much. go drive ANY manual... try sticking it in first at 15mph then report back,

And burnouts don't kill synchros. jamming into first at speed does.

Dude, driving it 'wrong' huh? Didn't know you were an automotive authority on how to drive a manual. But I'll drive my manuals the way I want. Been doin' it for 40 years. Funny, never had a manual fail yet. Back on topic. Gear oil doesn't jam gears as the op is describing and the mt is pretty stout for the Z and shifts good if your an 'authority', lol, like me. Oh, ten easy steps. That's for girls, dude. Can't you tell the difference? Report back when you do.

I have to ask too...why do you want to shift into 1st at anything above walking pace? Makes no sense. Maybe on the race track, but with the right gearing not even necessary there.

Idk what u want me to say? Ok so u have been driving a manual wrong got 40 years? Funny that u say that article is "for girls". I asked my girlfriend just now, "babe, when do u downshift into first?" She responded, "only at a stop light. Is this a trick question?" Funny that even my girlfriend knows better. And secondly i find it odd that u think girls can't drive manuals. Save that sexist crap for another forum.

I want u to tell me what logical reason u have for shifting into first at speed. Cuz I'm pretty sure chirping your tires on a downshift isn't one

ok man chill out unless you are a pro

im not downshifting to first while im going 15 - 20 miles per our, not even 10 or 5. im holding in the clutch while barely moving almost at a complete stop. even when im sitting there at a stop sign (not moving) sometimes it has trouble going into first unless i work it a little bit. thanks for sharing how to drive a stick also, i had NO idea how to until now.

I have no idea how to drive a stick either. i just move the lil knob around in the middle till something happens or it crunches (idk is that bad). that combined with blindly stabbing at the 3 little mystery peddles has seemed to work out so far
