Miss shifting, kinda, Whats rong with me Options

[creis]

I've had my car for going on 2 years and yet I cant stop doing this, almost every time I hop on the freeway I accelarate at a rather fast pase 3rd, 4th, 5th and once I get to about 3k in 5th (60-65mph) I pull it out of 5th and try and drop it into 6th I catch myself before I slam into reverse spin out and flip off the road but still why. it makes no sence to me that I always go for a 6th gear when I know I dont have one. Is it me or does the 5sfe tranny gear ratio feel like it should have a 6th gear?

anyone else have a problem with this, and does anyone know of a swapable tranny that has a 6th gear, I know the salara trany bults up, but I thnk its just another 5spd.

[soulshadow]

All I can say is that your an idiot..lol..im one too.
Anyways, shifting into R will not happen cause the tranny stops you unless you really jam it into R and no 5 speed is good enough cause the 5S is a weak engine.

[creis]

yeah I know you cant just slide it into rev, i mean I stop before I try, and yeah the 5s is weak but a 6th gear would make a little diff in acc. obvilusly not gana guain hp with it.

I get the same feeling cuz in 5th at 65mph its like the engine is at 4k RPM and it feels like i should shift again... I think i'm gonna do an MR2 transmission someday and hopefully it will have taller gears..

MR2 tranny = Celica Tranny

Camry Tranny = Taller gears

ohh ok... I just keep hearing that the MR2 Tranny won't have so much drivetrane loss.. How well do camry tranny's fit?

MR2 has the exact same tranny as the GT with exception to the shift linkages and other MR related workings. The Camry has the same tranny, with different gearing and a longer final drive... It's more or less a direct swap...

umm or you could just learn to drive a 5 speed....lol

taller gears would mean you would stay lower in the rpm range. when that happens, you would have less power.

the tranny is geared perfectly for the 5sfe motor. it dosnt hurt anything if you are at 4-5k on the highway.

thats not necissarily true about less power....cause it depends where in the RPM range it drops you....

Unless you're turbo charged or supercharged with a sh!t load of torque(at LEAST 200+ ft lbs at the wheels)... taller gearing NEVER helps 4 bangers.

yep ...they make them short for a reason .

think of it this way... with taller gearing, your 2nd gear now feels like 3rd gear.... ouch

[playr158]

well if you get nitty gritty you could change 1 gear....or so
just depends...like i said
for the jettas we have a 5th gear conversion which actually helps us and puts us in a much better part of the power band and gains power...
(then again thats a different car and tranny but an example nun the less)

and honestly what power are you looking to gain in 5th gear anyways on a celica? cause there isn't any there to start haha
i'd like a 5th gear conversion on my celica just to drop the rpms about a grand and save some gas

[Silver94CelicaOw...]

I know the 5SFE tranny uses a .820 5th gear ratio, and the final drive is also rather high as well. I would love a 6th gear, this has often been a huge thing for me since im always doing highway driving and our cars dont cruise easily at around 80-85 MPH without being at pretty high revs and possibly wasting more gas....although you can also argue that engines are actually more efficient at higher RPM's, but thats whole different discussion.

Would it be feasable to get a company to make a longer 5th and maybe 4th gear for us? I'm sure theres a company that could do this.....even better, make a full cryo-treated gear set with a slightly longer 4th and 5th gear that will stand up easily to the abuse of swapped and turbo applications. Maybe this is too ambitious, but think of all the Celicas and MR2's using the S54 that would benefit from this.

[lagos]

you would just end up spending thousands of dollars on tranny upgrades just to save a few bucks in gas. the celica GT/STs are already great with fuel economy

[Silver94CelicaOw...]

Alright, some of you have probably heard of this place, but I just remembered of a place i heard about called Level 10 Performance Transmission Systems (www.levelten.com). But at any rate, they seem to do just such work specializing in Imports...and turns out its only a 20 minute drive from my house...lol.

Art, youre probably right about spending alot of money on an already well designed transmission for stock Celicas, however getting a good condition E153 tranny from a 10+ year old MR2 is getting tougher and tougher for higher horsepower applications like a motor swap. Level 10 does group buys, and it would be great to see if they could give a respectable deal on a cryotreated or "bulletproof" gear set for our S54's, and maybe a longer 5th gear for those who want a better cruising gear for their stock Celicas. Maybe over my christmas break I'll stop by their shop and see what they think.

Anybody else interested??

Maximum fuel efficiency occurs at peak horsepower.

[Bigmeanbulldog55]

I'd like to lower my gear ratio for better acceleration. I'd like it so the car maxed at about 100-105. You never need to go faster than that, even on the track. I drive interstate sometimes, so I think the best thing would be a 5 speed to 100mph, and then a sixth gear on top of that for interstate drive. Or, just stay off the interestate.

[playr158]

wow ummm i'm not goin to even respond to the kind of idiocracy of that last post....

but actually a gear conversion once made...isn't thousands of dollars art...and can be done for a reasonable price...

but corey i think you should check it out its a good idea and get a decent ball park instead of tossing out a random "thousands"

Wow, you have no clue about condition specific gearing. Happens all the time on race tracks, especially with motorcycles and engines that have "cassette" style gear boxes to facilitate such swaps easily at trackside. The basic idea is to keep the revs at peak horsepower for as much as the time as possible for a given course. Remember when cars were geared to make peak horsepower and thus get maximum fuel efficiency at 55mph? Of course speed limits have gone up since then so now we have a bunch of cars cruising around at the speed limit while on the downhill side of the horsepower curve. What Bigmeanbulldog55 is suggesting is a little out of the ordinary but not total idiocracy. It's mostly out of the ordinary because street drivers aren't going to invest the time and money into developing something like this. Street driving has far more variables than a fixed course that can be planned for. The acceleration would be better but it could possibly loose drivability. No real good way to tell without actually doing it.

Please do explain. What is wrong with wanting the car geared as low as possible? Smaller gears mean quicker changes and faster acceleration. Instead of shifting and dropping down to 3.5k, I'd stay at 4.3 or something around there. It's just like having a six speed transmission without the 6th gear. There's nothing wrong with that unless your wanting to drive at a constant high speed a good bit. Why do you think the Chevy and Ford guys are always putting new "gears" in the rear ends of their cars? Do a little research before you go referring to someone’s post at "idiocracy."
