You know the scenario. You are driving the S hard out of 2nd and then 3nd when your brain farts and you wind up back in 1st and chills run down your spine because your car screames like you are whipping a cat. How bad is this for our cars/tranny/engine/joints/etc.?

 

how do you wind up back in 1st from shifting to 2nd?

 

I think he means the 2nd to 3rd shift

Right where the cylinders are making holes in the bonnet

Depends on what rpm you shifted back to 1st after 2nd gear...

 

At the limiter!

 

My car has 457s and a short throw shifter. The gear box is more mechanical in feel as well as much tighter. It takes more thrust to travel the shorter throw. I never did this with stock config. I know it can't be good but does the electronic limiter protect the car well in this instance? What about the drivetrain as a whole. I don't think I hurt my car but I imagine this would contribute to wear tremendously.

 

If you shifted from 2nd back to 1st instead of 3rd at the rev limiter I presume you had a serious mechanical overrev and the rev limiter will not have kicked in because the wheels that are turning and linked to the drivetrain will force your engine to go up in revs way beyond redline, no mather what Did you engage the clutch asap? Did the back wheels spin? There are more technical people over here that will tell you what tests to run on your engine... Good luck anyway, hope everything turns out ok!

 

Thanks. The back wheels did spin but not much and yes, I immediately corected into third. It seemed like the limiter did not kick. The clitch grabbed fully and did not slip because it was a quick shift. The car is running fine but I will never do that again.

 

How fast were you going when you slipped it into 1st gear?

 

9000rpm, he shifted from 2nd back into 1st instead of 3rd at the limiter in 2nd

 

You have to understand what the rev limiter does. It cuts off fuel once you get to it (just slightly over 9000 rpm for AP1). It does NOT prevent a MECHANICAL over-rev. You are NOT protected in such a scenario. Your rear wheels will drive the engine well beyond the rev limiter.
If you were at 9000 rpm in 2nd and somehow managed to slam it into first, you may have propelled you engine speed to as high as 13,500 rpm. The engine is "OK" up to about 10,500 rpm for a very brief moment, however, it is suseptible to "how quickly" it got there. An over-rev generally catapults the rpms up in a very rapid fashion and even though it may not have gone much over the critical threshold, it may have accelerated up there quickly enough to cause some valve damage - damage which may not become evident for some time.

Rather than "supposing" you do this or that, how about just telling us exactly what happened, giving details as to which gear you were in at what rpm and approx. what speed and what gear you ended up in and what exactly you did and for how long?
