you blipped it and didn't really heat up the main and rod bearings. if youre a believer in breaking in the engine it wasn't the worst thing to happen.

as far as over rev, how fast were you going? then we can figure out if you were in the RPM range for damage.

^^^THIS... Break in is not just for your motor, it also includes the transmission and rear differential. If your engine is running ok, no problem. I have seen a few threads of people doing this and it bent some valves.

As long as you didn't mechanically rev (as explained above its not saved by the computer) it way beyond capacity you are ok. How is t running any leaks and new noises?

Exactly!!
I hate to admit it, but I managed to shift 3-2, at redline while in 3rd - on the dragstrip in my 4th Gen SS. Horrible experience! The force would have put me through the front windshield if I hadn't been wearing the shoulder belt! The result was smacked valves and a mess of bent pushrods.

From that day on, I started shifting from 3rd to 4th backhanded by rotating the palm of my hand 180 degrees so it's facing the passenger door instead of the driver door. You don't "grip" the shifter using this technique, but rather you"push" the shifter into 4th with the palm of your hand. There is a natural motion pushing away from gate for 2nd gear when you do it like is, thus avoiding the dreaded 3-2 misshift when trying to upshift into 4th. It's just as quick a shift to make this way and it's easy to use on road courses as well, anticipating an upshift from 3rd to 4th. Try it. It works.

Best regards,

Yeah it's ruined I'll give you 2500$ for it

Yup. 100%. Ranger has some really good instruction videos that explain this exactly. It's all shifter technique.

Found this:


Good instruction/explanation of this - how to shift from 3rd to 4th at 2:20.
Also good tips for the 2-3 upshift...

I can't believe some people still think that a Rev limiter will stop a mechanical over Rev. That's truly sad from any man who calls himself a "car guy". Especially one who drives a stick.

I still do this out of habit on every 3-4 shift even when I'm not racing. It becomes 2nd nature after a while.

Lol..... DEFINITELY not true.

The reason the transmission was invented was so a car could go faster than the engine can rev. A rev limiter can only shut fuel off. You jam the transmission into a lower gear than the engine can turn for the speed the car is moving the engine WILL over rev.

LMAO. I'll give you $3000. Seriously though, you're probably OK up to redline or even a little over. It's when you zing it well past redline that you're in for trouble.

You know, I've often wondered in this day of rev matching, hill assist, and solenoid lockouts, why not put a lockout on each gate and simply lock out the ones that would result in an over-rev based on your current speed? Seems like that'd be an easy thing to do! I realize there could be times when you want to pre-shift into a gear while slowing so you'll be ready to release the clutch at the lower speed, but it could at least be an option.

I concur,if it happened multiple times you'd be in trouble but should be okay with one or two occurrences at the most.So I guess 2500 won't get it

[Drags1998]

Fastball, I suppose your right!! What I should have said is: Except for 1 choosing the the wrong gear by mistake you could not hurt it!!!! I have NEVER {including 12years of drag racing w/manual trans} chosen the WRONG gear. Its hard on a forum to have everyone on the same wavelength!! I know that driving talent varies between people and I should have thought of that. So, I stand corrected!!!

That's actually a really great idea. I'm surprised no one has come up with that.
