Before I answer your question lets take a look at what an automatic transmission is.
Its a funny looking thing bolted to the rear of the engine and it "transmits" power from the engine to the wheels.
They operate with hydraulics. The RPM of the engine turns a pump which sends fluid thru a series of ball valves and springs which are "preloaded" and when the pressure of the fluid reaches the "preload" value of the spring it opens a ball valve and fluid flows thru a passageway and exerts pressure on a "paw" which in turn shifts the gears in the transmission.
Now an automatic transmission is a very delicate piece of machinery, much like a woman. You have to treat it with kidness and TLC and it'll be right there for you, kinda like the other day when me and my girl were out on a picnic and I popped out a surprise bottle of her favorite wine. She got all gigglely and said to me,(now hold onto your hat) she says, "you know what, you need to buy yourself a brand new Rifle. No special reason 'cept that you want one. Heck honey, I'll just wait for that engagement ring.". Sure enuff...thats what she said...sure as I am standin here in a cold bowl of warm water wearing nothing but my Scooby Doo boxers typing this.
Well I was just about to answer her when all the sudden this idiot come rippin buy us sliggin dirt and dust from here to yonder covering both of us with it. She jumped up all in a tissy and yelled that it was my fault for bringing her out in the woods when I should be in town with her buying her that engagement ring and plannin our wedding.
After about a half hour driving back home I figured that she had calmed down some so I asked her about the new rifle she said I could buy and got THAT look from her, you know, that sideways, eye cutting, wish you would just burst into flames and fall off the face of the earth look. Not a pleasent ride back home....oh yeah...what was your question? :smile:
Thanks bitmasher. I was just funnin with that post.
Brewman, Some vehicles do have an electronic shift control switch. It is used to change the shifting points when hauling a heavy load.
My '97 Toyota 4X4 with automatic had one. It gets its info,ie; RPM, speed, and various emissions sensor signals, from the ECM which also controls the EFI.
what it does is it stretches out the between shifts in the lower gears. This will allow your engine to gain some HP and torque from the higher RPM before the transmission shifts into the next gear. Mabe this is what you meant. Hope it helps.
Just please pay attention to where you go "ripping" and if you spot a nice couple picnicing then by all means...slow down for a moment till you get clear of them. :smile:
Rather than spend my hard earned pennies on those cool Shoot-N-See targets or even the preprinted targets at sporting goods stores, I save a few bucks for weekend plinking sessions by using paper plates as targets. A 100 count pack of paper plates costs less than a 10 count pack of preprinted targets.
If you are playing with something like a semi auto AK, or building a young shooters confidence with a 22 or shotgun, those big eight inch blanks are perfect for putting holes in all...
