I just wanted to reply AirMoore here wtihout hijacking the computersoc's thread NYS Thruway any further
:shock: Oh my Goodness! I'm sorry if my post provoked you so much, I hope it's nothing serious ops: :roll:Originally Posted by AirMoore
Although if what you replied here is what you consider short, I can imagine why the website didn't like your original one :wink:
I believe it's got a lot to do with what you were refering to, specifically the part where you are talking about transmission explosion. I was just trying to clarify what conditions would have to be fullfiled inorder for a tranny to explode. I would also like to add that for a tranny to explode you would really need a tremendous amount of force, such as en engine producing a 1000 or more hp, a set of huge slich tires and a drag racing style cluch.Originally Posted by AirMoore
And yes, if by "other DTS componet failure" you mean tires or clutch slipping (which are the first parts to "fail"), you are proving my point
Again I don't think I misunderstood you, maybe I wasn't precise enough in my analogy, and I apologize for that. I wanted to describe the situation where the car is being driven up the hill on a snowed in road and it starts to slide downhills. First the driver is, naturally, try to brake, the car keeps sliding so he let's go of the brake (at that point wheels start rolling backwards) and then he releases the clutch and applies the throttle (at which point the wheels quickly start sppining forward). I didn't stress this before becouse I didn't know what is the exact reason why you thought the gearbox would fail (and that makes this less than precise analogy anyway, as in this case wheels going in one direction at 60 mph and then moving in the other 10 - 20, while in analogy it's the other way around). What seems to be bothering you here, as much as I can understand, is wheels turning in one direction and then suddenly in the opposite direction. The friction between tire and snow deppends on the tires of course (size, thread pattern, compound, all season or winter....) as well as the surface, but assuming that you've already started losing control, means that the friction coefficient is low. And as you say the constant pressure is not the problem, but the shock is, I drew the conclusion as stated above. If that is so, you could expect the gearbox to explode/fail in the situation like when you have car jacked up, wheels spinning freely, start the engine and spinn the wheels to a velocity equivalent of 60 mph then shift in reverse and heve them spinning in the opposite direction instantly. And what is another thing that, I'm sure, is making you judge this methode like you did is what I said about releasing the clutch in my first post and agiain I appologize if it gave anyone wrong ideas. What I assumed that person driving a car equiped with a manual knows how to operate the clutch and wouldn't take the word "dump" literally. I wanted to say clutch needs to be released fast and not just "dumped" like if you move your foot of a fully depressed pedal to the left and let it "pop" back into position or something similar. On a manual car amount of stress applied to the drivetrain is proportional to drivers skill in operating it (particularly the cluch) and if he/she has basic knowledge and a little practise they shoud be able to do this without cousing any significant stress on th drivetrain. Clutch is expendable part of the car that wears out just like the brake pads (which are made of a very similar material) and is meant to be controllably slipped by drivers, I'm sure that anyone who knows how to drive a manual is aware of that, at least subconsciously, becouse they have to do it every day. And iven if a driver dumped the clutch violently, chances that the gearbox fails are relatively low, and it would take many of such stunts to destroy it.Originally Posted by AirMoore
Ok, I mentioned the driving school to stress how much combined abuse is transmission able to withstand and that is real: at least a dozen students goes "through" each car, averaging 30 hours, and overall such incidents happen 3 - 4 times an hour (on average again) and include all of the above and many more like releasing the clutch to early, before teath gave completely engaged, and yes it happens often that a student shifts in a first gear by mistake while driving at various speeds including high speeds like 60 - 80 mph. It may not happen every day but it certainly does.Originally Posted by AirMoore
Now about engine wear, I don't believe that you are damaging the engine significantly as you are trying to clame. Engine is certainly built strong enough to take abuse of stalling as well as skyrocketing the rpm's and in fact all driving students here are tought to brake car with the engine instead with breakes whenever posible by downshifting. Of course it's not recomended to shift in first gear while doing 80 or so (not trying to say that it's not bad for the engine to do thi but I still believe clutch and tranny would take more stress from this than the engine) , but I can say that I haven't heard of engine failure becouse of it, and cars in driving schools here literally take that kind of abuse dozens of times every year.
And again thanks for proving my point , thats pretty much what I said in the first place: tranny wouldn't explode or fail instantly, and the tires and the clutch would be first to "fail" and bleed off energy. As for major failures, unless you are stuck with a very poor tranny or one just about to fail, you would need to pull this stopping procedure hundreds or thousands (if you are using the clutch properly and slip it manually to reduce the shock) of times before the tranny would fail.Originally Posted by AirMoore
And please read my post thoroughly, I never said this was actually beneficiall for the tranny. :idea:
So now you say you are familiar with this and you've already seen it done by your friend?? And he is good at it, meaning he's got a lot of practise?? I take the transmission didn't explode or fail every time he tried it :wink: Or even after many attempts :? Doesn't that defeat your own point? I'm aware you admitted of exagerating in your last post, but I dont know how much. Did you, by exageration, mean that tranny would explode but the bellhousing/transmission shield prevented gears from flying through the cockpit windows/hood, or that meybe you would have just squirmed in your seat expecting an explosion but nothing happened? :? :?Originally Posted by AirMoore
Anyway if you think you have a better method you should have just said so insted of attacking mine, especially if you've already seen that mine works, and we could heve been discussing the differences, but I'll leave that for later, this post is getting awfully long already. :roll:
I can say I agree with you here, my points were (as can be seen from my previous posts in the other thread) is that it would take A LOT of such abuse to significantly reduce the lifespan of your tranny AND as your friend says this is something to do when "all is lost", and it's pretty unbelievable that you would loose control of your car and stop this way hunderds of times, how much would take to damage the drivetrain would. And even if that is exactly what happened, I thing a price of a new tranny is negligable compared what you'd be paying if you crashed your car a hundred times :wink: :wink:Originally Posted by AirMoore
In the end I just want to apologize for such a long post(s), I didn't mean to write any more than my original post but as others was getting in depth and technical, I had to try to clear things up a little. Hope noone is offended, we are all on the same side here :wink:
