I am not expert on Trannys so forgive me, but is there anyway to merge gears 1 - 2?

engaged in two girls, I mean gears at once lol I actually missed typed that and decided to keep it in there, but ya


gear one and two?

anyone

What do you mean by "merge?" I've taken apart and rebuilt a few auto trans. so I might be able to help.

Omron

Thanks for replying

what i mean is this....


Steve Knickerbocker wrote that "Smooth shifting transmissions accomplish [smoother shifting] by being in two gears at once when shifting up. It's known as shift overlap. Shift kits reduce or eliminate the shift overlap and speed up actuation of the shift, hence the harder feel to the shift. A shift kit will reduce wear because you won't have the trans trying to be in two gears at once."

ooooh i think i know what your talking about, its in first gear with second already engaged to the transmission and semi on the clutch for seamless upshifts? is that it?

mgs_freak

So you're trying to make sure that you don't have one of those "smooth shifting" trans? Or are you trying to get a smoother shift? You're second post confused me. I thought you were trying to find a way to be in two gears, but the second post says, to me, that you're looking for a shift kit.

clarification?

I just went and read all the comments that Steve Knickerbocker wrote, and that's some trippy stuff man. I never got that in depth with the valve body, I just took it apart, replaced things with stock parts and put it back together. Good luck with whatever you're trying to accomplish.

Omron

sorry I mixed up my quote, I ment to quote something else,

what I am getting at is, away to force the tranny to ignore gear one, is there a possible way of doing this, maybe something programed into the ECU?

I know everything has to do with Load / Throttle / Ratios and other variables, but other then place the car in D2 or 2. is there a way to have the car not use gear one in regular drive?

if it sounds like a odd *** question, thats cause it is...

anyone know?

forget the shift kit thing, i didn't put it togteher right

mgs_freak

You could give Jaguar a call I guess. I think they're new auto trans don't shift into first unless you come to a complete stop.

Seriously though, I bet there's a way to do it. You'd most likely have to do something to the valve body (along the lines of blocking passages for fluid) that would force the transmission to go no lower than second gear.

I'm curious though, why don't you want first gear? You only get 4, I like to use all of 'em.

wow ok i'll give my two cents. if you want a harder shift, i was told to pack in the clutch plates, suposeably thats what was done to my friends accord and it cherps 2nd on spray.

mgs_freak

Not trying to offend you tim but automatic transmissions don't have clutch plates.

Omron

number one reason is fuel consumption reasons, number two reason is that anoying shift you get from 1 to 2, when your fluttering the gas a little, feels more like a thumph instead of a easy shift....

but it was just a question... but I am interested if it could be done

mgs_freak

It most likely can be done, but it's not worth the headache. Fuel useage will not decrease that much, if at all. You will accelerate slowly all the time until you get into the proper powerband. You could end up damaging your engine also. If you "lug" the engine, in other words, demand too much power with the tranny in the wrong gear, it is usually more damaging than overreving. Seriously.

If you want to save money (gas) don't pay someone to mess w/ the tranny, just keep feathering the throttle. At least that way, if you need to go fast, you can.

umm dude an auto tranny has clutch packs several plates put together

mgs_freak

Yes, I know they have clutch packs but if you pack them, it automatically engages that gear. The plates have very small and specific clearances.
