2001 Corolla redline speeds for each gear (no tach)

[sureshot324]

I have a 2001 Corolla 5 speed with no tach. It really bothers me not to know where redline is since I'm always afraid of over reving it. Can someone tell me what speed this car redlines at for each of the 5 gears?

Redline is somewhere around 6,000 rpm.

If it's automatic, don't worry about it. The auto tranny will shift before you over rev it. If you have a manual tranny, that's another story.

Th 01 Corolla redlines at 6K exactly.
In the 4 speed auto, you can take it up to 6200 - 6300 RPMS.

I wouldn't take it much further than that.

LOL its clearly stated that its a 5 speed manual. I swear people just look at the title and post

You can shift by feel.

Don't forget the rev limiter which is there to prevent any engine damages.

If you really want to know the RPM I suggest getting a tach installed. For low RPM shifts I don't see a point but when shifting at high RPM I would.

I have no problem driving it by feel, it would just be nice to know where the redline is. A Corolla motor needs to be reved high to get good power, but I'm afraid to over rev it since I have no idea when I'm getting close to redline.

What I want to know, is what speed (mph or km/h) it hits redline (around 6000rpm) because that would give me a good indication of what my RPMs are just by looking at the speedo. I've thought about putting in a tach. I might consider it in the future but I'd really rather have the stock tach cluster, which unfortunatly would be much more expensive to install.

What rpm does the rev limiter kick in on an 01 Corolla?

i saw someone mention rev limiter. if you have an automatic trans and you're going 69mph, and you wanted to engine brake by shifting to L, that would damage the engine right? (manual says don't shift from D to L above 66mph)

Pretty sure you are more likely to damage the transmission.

Kinda depends. If you are going uphill you can hit redline without going very fast. Going downhill, you can get going very fast w/o revving the engine at all. Without a tach, I think you can only go by feel.

Do you you have an owners manual? It may state max speed for shifting, but that may not be rpm max.

oops i meant tranny

wow, people need to read the first post before they reply.

vibebreaker - it would either over rev the engine or just not shift at all and slow the engine down before actually shifting down. depends how the auto tranny is set up.

tigrpal - the rpms are always exactly the same at a certian engine speed, it's a gearing issue, the wheels spin at a certain ratio to the speed the engine is spinning determined by what gear you're in. it doesn't matter if you're going uphill or downhill
EDIT: on automatics this isn't the case, but he has a manual.

sureshot324 - wish I could help you, I know exactly why you would want to know this. but I don't have a 01 corolla :-P. I hope someone lets you know. you're probably aren't over revving it though, just shift when you feel the power start to drop off. a lot of times redline isn't the best place to shift anyway. I would recommend getting a stock corolla gauge cluster with a tach though, big aftermarket ones are hidious. sorry I can't help.

On a flat road, My 4 speed auto(which has the same internal engine parts) hits 6000 at 40 MPH in first gear on flat ground.

the 5 speed manual and 4 speed auto have different transmission, but the pistons, crankshaft, etc are the same. and I belivee that the strength of those is what determines a cars redline. the 1zzfe engine is safe to operate under 6k rpm without damage.

that is why I mentioned why my 4 speed auto redlined at what it did.

the redline might be the same (sometimes redline is determined by the tranny too) but the gearing in the auto tranny is totally different, so this isn't very helpful :-P

I just remembered that I stumbled upon a redline calculator a while ago where you have to put in the exact ratios of your tranny, I'll try to go find it again.

Ok here goes the formula for calculating your engine and vehicle speed:

Circumference of tire * RPM
------------------------------------ = vehicle speed
Gear ratio * Final drive ratio

For example for a car with a tire of 82" circumference, 2.9 1st gear ratio, and 3.97 final drive @ 1500 RPMs
82in * 1500 RPM
-------------------- = 10683.575 in per minute
2.9 * 3.97

Interesting. Anyone know where I can find the gear ratios and final drive of an 01 Corolla?

Both, when engine braking, shifting from D to L or 1 or 2 it may cause damage to the tranny. Depending on which gears to which gear, downshifting will bring the engine to a very high RPM and kaboom.
