TRE - Taller 5th Gear
 

Wondering if anyone has any experience with the TRE taller 5th gear. Readin' a little about the TRE Exchange and a taller 5th gear is an option. Does anyone have any suggestions? I am mainly wondering on gas mpg and driving down the highway without going 3000rpm at 55-60mph.

Re: TRE - Taller 5th Gear
 

Yeah, it'd help with that. It'll be kinda doggy at lower rpm though. Cars with lots of torque usually have really tall overdrives like the Viper and Corvette. The Viper is at 1200 rpm at 60 mph in 6th gear.

Re: TRE - Taller 5th Gear
 

I believe 95talonracer was having one put in (hope I remember that right). You might ask him if he's running it yet.

Re: TRE - Taller 5th Gear
 

well, for whatever reason talonracer95 was banned, and hasnt been allowed back on even since his ban was up. He did get that TRE 5th installed, and has the TRE tranny on the car.

Re: TRE - Taller 5th Gear
 

Wouldnt a taller 5th gear be bad for drag?

Re: TRE - Taller 5th Gear
 

You really don't ever go into 5th gear when drag racing a DSM. Even the very fast guys don't have to with the help of high revlimiters and larger diameter tires. The stock 5th gear is perfect for acceleration though, if you are do have to go into it on high mph highway pulls. Some cars when you go into 5th, it more of a cruising/gas mileage gear and the car falls out of the spooled up turbo powerband. A long 5th gear would probably be useful for a Bonneville salt flat car and for better gas mileage/less noise on the highway.

Re: TRE - Taller 5th Gear
 

Would a taller gear affect the gearing in our rear pumpkin on a AWD?

Re: TRE - Taller 5th Gear
 

Alright, thanks guys. I wont be going with a taller 5th. Just wondering because I was wondering if it was any better on the car (highway speeds/mpg).

Re: TRE - Taller 5th Gear
 

No. This only changes 5th gear, not the front diff/rear diff ratios.

Re: TRE - Taller 5th Gear
 

I might do it at some point. The engine is just spinning too fast at 80+mph. It's wasteful when the engine is torquey enough to do it at slower revs.

Re: TRE - Taller 5th Gear
 

Hey I did get the taller 5th gear and I would suggest it to anyone. They say the estimate gas mileage is like 30MPG. It cuts the rpm down in 5th gear so it wont rev as high in 5th either. Let me know what you choose to do.

Re: TRE - Taller 5th Gear
 

I decided against getting a taller 5th. Went ahead and ordered the Stage 2 Exchange though. My Dodge Intrepid is going to real shit so I went ahead and bought a trans from TRE.

I called the local shop and they want 360$ for R&R on my trans. :eek: That's with telling them I already pulled the battery/box and intake and all the stuff thats in the way out. All they have to do is remove axles and DS and drop it. Is that too much for R&R? Should I keep looking?

Re: TRE - Taller 5th Gear
 

I would get the 5th gear man its cheap and you will save alot of gas.

Re: TRE - Taller 5th Gear
 

Bring your car to one of the local sponsor shops (one has much lower labor rates than pretty much any place in the Cities) and I'm sure they can do your tranny removal/installation for a decent price.

The taller 5th gear is a great idea, it'll improve MPG and save wear and tear on your engine.

Re: TRE - Taller 5th Gear
 

What is the RPM difference with the TRE 5th gear while crusing at around 70mph on the freeway?

Re: TRE - Taller 5th Gear
 

I thought they used to say it was 10%. I would love to dig for facts, but I have dialup.

Re: TRE - Taller 5th Gear
 

It says that it is around an 8% taller 5th gear so to my understanding at 3000 rpm of a normal 5th gear this one will rev at 2760RPM. An average of 27-30 MPG. Its worth it. It is only $150. If you were to drive 100 miles a day and got 22 MPG now, then if you got the taller 5th gear you would get say 29 MPG average. That is 7 MPG more. You would save roughly $6 a day. That means in 25 days of driving you will pay for the gear itself and after that you are just saving even more money for additional parts for your car and not gas.

Re: TRE - Taller 5th Gear
 

If you want to save gas, get a Prius. You can even get VFAQ tips from Tom Stangl for them now. The old DSM'rs have gone to the gay side.

Re: TRE - Taller 5th Gear
 

I don't think your gas mileage is going to go up 7mpg. I currently get 27mpg with the AWD Talon. I would consider 1-2 mpg a decent gain. The car vibrates pretty bad at 80mph with the RPMs at 3500+.

Re: TRE - Taller 5th Gear
 

although I dont expect 30 MPG, any increase would be awesome, the larger problem is the high RPMs on the freeway, its loud and annoying.

Anyone who is having their tranny cracked open would be wise to opt for the taller 5th gear.

Under TRE's "Genuine Mitsu Parts" page, they list the gear itself for $220, If it is a mitsu part, shouldnt it be available through brookdale mitsu?

Its about 1/3 way down the page.

Re: TRE - Taller 5th Gear
 

I live no where near the TC area brother. I live in the boonies, 1 mile from SD border. I would love to bring it into a Sponsor shop but I can't truck it down. I was just hoping to get an estimate of what someone else has had theirs done for. They wanted 360$ for the R&R. I gotta save my money. I'm trying to build a reliable DSM..

Re: TRE - Taller 5th Gear
 

Do it yourself then, its really not too tough, just take it slow and label everything.

Re: TRE - Taller 5th Gear
 

How much are they doing for you. Are they just pulling the tranny ad doing the work, or are they reinstalling it to.

If they just do the pull off and rebuild that is about 3 hours. If they put it all back together it is more like 5 or 6.

Re: TRE - Taller 5th Gear
 

They're just pulling the old one out, putting the new one in along with a clutch and flywheel, I'm supplying the New trans and the fluids.

I did alot of the work myself, disconnected all the hoses, wires, sensors, everything but the axles and the DS. Thats where I got stuck and confused and I do not have the tools to do it. I gave up.

I dont know..

Re: TRE - Taller 5th Gear
 

^ and the Clutch and Flywheel.

Re: TRE - Taller 5th Gear
 

The drive shaft comes off with the T-case, just 17mm bolts and the same size is used on the suspension (if it's a 1g, you don't say).

Re: TRE - Taller 5th Gear
 

Most shops don't want to work on a car that someone already started working on and aren't going to offer a discount when a car comes in half torn apart.

Re: TRE - Taller 5th Gear
 

Going from 3000 to 2760 would never yeild 7 mpg increase. I cannot imagine that it would really affect your milage more than 1 mpg, thats only a 250 rpm difference at 3000 rpms. Completely not worth it IMO.

Re: TRE - Taller 5th Gear
 

I think it depends on how the car is setup. If it is made for high revs and dogs in the lower RPM then no, but if it is a 2.3L stroker then a taller gear would be ideal.
It also wouldn't be worth it if the car is making stock HP i would think. I would think the engineers would have put the 5th gear in the most efficient range. In this club though most cars are making good HP so that would throw off the calculations.

I would love to see a data log of a before and after the gear installation to see how the car is running. To measure by tank there are a lot of variables. I have had my car running in the 27 all the way down to 21 on highway depending how I am driving:D

Re: TRE - Taller 5th Gear
 

We don't like doing it either. It becomes the "who is responsible for what" argument.

Re: TRE - Taller 5th Gear
 

I hear ya. But damn my working enviroment blows. Unfinished garage with soil for a floor.. I dont know, You guys are making me want to drop it myself now. I haven't a clue on how to get the front axles out of the transmission..(?)

I just got it all back on the ground ready to roll onto a truck and now I'm about to go tear it all apart and try to pull it out again.. Wheres the DSM transmission removal for dummies book when you need it?

What I've done;

Raise on stands, took front wheels off, took out pass. side inner fender/fender, disconnected Speed gear, disconnected wiring from trans, removed batt./box, removed intake piping, removed shift cables, trans-to-block bolts, I think I got everything but the DS and the front axles, thats where I'm stuck, I havent a clue on that nor have ever done that before. I am willing to learn but damn.. None of my buddys ever did this extensive of work so getting help is hard.

Heres what I think I have left to do from where I left off before I put the wheels back on;

Support engine, support trans, disconnect DS, disconnect l/r front axles(?), removed trans mounts (1 ?), then drop it and put the new one in? The new trans aint here yet so I got time but cheese n' rice brothers im confused..

Re: TRE - Taller 5th Gear
 

What year is the car? You don't have to support the engine if it's a 1G.

Re: TRE - Taller 5th Gear
 

Sorry, it is a 1g. 93tsi.

I forgot to add I also took out the exhaust.

Re: TRE - Taller 5th Gear
 

Tested my new 5th gear at 70MPH today and it revs ay 2650 even. Alot nicer drive at that speed then before.

Re: TRE - Taller 5th Gear
 

Are you AWD?

Re: TRE - Taller 5th Gear
 

That's quite a drop if it's AWD.

Re: TRE - Taller 5th Gear
 

My advice is no good, please delete.

Re: TRE - Taller 5th Gear
 

No it is fwd but same results for awd according to tre. This gear is awsome. It just coasts now instead of wining out. Well i guess it isnt that dramatic but still. For 150 it is all worth is on everything.

Re: TRE - Taller 5th Gear
 

FWDs are geared longer than AWDs to begin with. I am at almost 4000RPMs if I try to cruise at 80mph.

Re: TRE - Taller 5th Gear
 

I have had this TRE tranny in now and put over 1000 miles on it. It is great so far and the 5th gear seams to help quite a bit being that it revs out less on the road just driving along.

Has anyone else gone this route as well yet?
