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.

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.

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.

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.

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?

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.
