I came across a few references about corolla fifth gear swapping, but couldn't find any threads on it. ( Ya, I know... newbie right!) I will be driving it back and forth to school about 200+ mi. a day, 90% highway. (80 mph average = high r's right!?!) From what little I caught, this would be a very cost effective mod!! (mpg's/rpm's) If this can't be done, can anyone recommend any other cheep alternatives for this?
I bought a 01 about two months ago, (going back to school in style!!) and drove it about two weeks, before putting it up for mods. (first round any way. lol) Pre-kitty gut, (thanks for the "heads-up" posts!!) injen CAI (thanks littlerocketspyder), (mongo's, and rear wind screen, self made. sorry, single parent student), Infinity system 7541a amp w/ 2- 6020cs (pair in doors, pair in center console sides) 3.5"'s (center ch. console), and a 8" polk momo in a F.G., side fired, U.D. box. :rockon:
Look for the fiber glass U.D. sub box, to be released on SC, SOON! It seems alot of you are looking for one, and seems this is where I can do my part! Besides, I Don't want to join the party empty handed. :popcornsmiley:

I have done this on my car and Daspyda's. It drops the revs to the same level as the 2zz 6 speed.

You need a 2003 corolla 5th gear and a 5th driven gear. The swap can be done while the transmission is still in the car by removing 3 engine mounts lowering the trans side of the driveline and pulling the tail housing cover.. HOWEVER getting 5th driven gear off is not easy and requires special toolage.

would you mind specifying what kind of special tools? gear removal tool i assume? so basically swap the parts correct? nothing else needed, don't have to drill anything, and everything goes back fine and just drive away correct?

Thanks LR

do you know how much these gears usually go for?

I'm really interested in this as well. I would kill to get the RPMs down on the highway. Out in west Texas where I do most of my driving the speed limit is 80 on the interstate. It really sucks running over 4 grand most of the day.

It is a specal service tool from toyota. A regular gear puller wont work at they are too thick. :( I made one from some heavy angle iron....

There are no tricks to it. Just changing gears.

It is not the removal but the installation, how are you installing the input shaft gear without supporting the bellhousing side of the input shaft? That input shaft has a plastic cage on the input bearing how are you pressing on the gear without putting stress on the needle bearing cage. Also why won't a 98-2002 gear set fit, is it just 03 only?

Thanks for the info!!
OK, a little beyond my capabilities!! But it sounded cheap to have it done at a trany shop from what I caught. ($200-300) How much would the parts cost used, and would anyone have them, or know where to get them? This really is more than worth it for my needs!!!

The driven gear is a press on the free gear is ont he bearing.

The trick is to boil water put the gear in the water then install it asap. It goes on without much pressure. Fwiw there are snap rings that hold the bearings inplace on the shaft. They can't move beyond the snap ring and as long as the gear is hot (expanded reducing the interfeence fit to almost nothing) youw ill have no issues. :)

The 03 has a talled gearing iirc. Been a while since I did the research on this one.

I'm really interested in this type of mod. Would any transmission shop be able to make the gear swap (5th)? Also, do you simply go to Mr. T to buy/order the part/ gear? Roughly how much do you think the swap would cost and what specific parts/ part numbers are needed? Lastly, since the 5th gear is taller than the existing 5th gear, is there a significant loss of acceleration in 5th gear compared to the existing 5th gear? Is there a large gap between 4th and 5th in terms of acceleration? Sorry for all the questions, but I'm really interested in this, but don't want to spend $2500 for a 5 speed transmission.

Parts will be a few hundred tops. Go to toyota and order a 2003 corolla 5th gear and 5th driven gear. That's it. It is only about 400 rpm at 80 mph not much different at all in acceleration.

Finding a shop that will do it in the car may be challenging.

WoW why would you spend 2500 for a 5 speed transmission? You could do a 6 speed for about 1k..... That would also get you the same lower crusing gear but 5 gears that are deeper for better acceleration. FWIW This is THE best acceleration mod you can do for the 1zz n/a IMHO. How about 20% more pullin 4th gear?

Actually, I miswrote- I meant $2500 for the MWR 6 speed as advertised on their website. I wanted to keep this economical as possible.

The special tool to fit the 5th gear can be found here http://toyota.spx.com/detail.aspx?id=275&g=16 . Not sure of the price. You have to consider the expense of the special tool against how many times you are going to use it. Scince you probably only going to use it once, is it really worth it? Littlerockets method is probably your best option. If you're feeling adventerous, do like I did and make your own.

And that is crazy as well. You can pick up a low mileage 6-speed for under $1k. I've bought two, the second was only $750.

I looked it up on Mr. T and the REPLACER,GEAR is $24.64 MSRP but a buy price of $30.00 If it make my life easier the $30.00 is well worth the cost and time savings. Thanks for the parts number..

Yeah figure 700-800 for a 6 speed and 200 for a shaft and you have more performance and more fuel mileage.

Thanks for the info rocketman.I think I heated mine in an oven but still remember having to tap in on with a driver, maybe I just didn't get it hot enough. I also quit doing the research on the gear set when I went 2zz/6 speed. I thought the 98-2002 gear set would fit and it had the right tooth count so it may be the same part number until 03. I do remember pricing the parts at Toyota and they were right at 200 bucks about 2 years ago. This would be a perfect mod to do when getting a new clutch. By far the cheapest way to get a lower rpm top gear for the highway.

anyone know the part numbers for these gears or just tell the parts counter guy the gear names?

I just called Carson Toyota they found the part # right away. 3600 RPMs @ 80MPH hear I come:)

Does anyone have a pic of the transaxle with the cover removed to show these two gears? Or a schematic you could mark up to identify them and show their location relative to the casing?

Are they immediately behind this cover, or is there more digging than that?
Thanks!
