Question Taller 5th gear for 04 FXT 5M?

Re-posted from Forester41 forum - no joy there...

My dealer needs to open up my tranny (again) to replace synchros... I'm thinking of changing 5th gear at the same time - I'd like to drop 500 to 700 RPMs. Does anyone know if this is possible and where I'd get the gear?

the 5th gear set is independent from the others, so any 5th gear set with a similar hub/syncro design would work. i think all 5th syncros are the same too, but i would stick with 99 or newer. just find the model that has the ratio you want, get the vin#, go to subaru parts and buy a 5th gear set.

Interesting thought, especially with today's gas prices.

Any real world experiences with someone doing this?

I think you're out of luck with this one. The gearing in the FXT is the same as the WRX, and that's probably the tallest 5th you'll find. Your only options are either taller tires or a new final drive, but that will change the gearing in every gear, not just 5th.

I don't recall my old bug eye being over 3k at 70MPH? But it's been a while too, and I've been pampered by a 4l60E in a suburban for over two years.

Transmissions are the same, the final drive is different. The wrx is 3.90 and the fxt is 4.444. Someone will correct me if i'm wrong. Alos I think you are out of luck unless you change your final drive to wrx ratios (3.90) to drop those rpms down but this will also effect every other gear aswell.

Our USDM 5th gears on our 5spd Subarus are among the the lowest gearing there is.
put in a WRX tranny and rear diff and you'll be fine. Then the WRX guy would LOVE your tranny!

According to Unabomber's FAQ, the FXT 5th is .780, compared to .738 for the WRX.

I don't know if they are interchangeable, however.
From the FAQ:
Quote:
How much are brand new, fully assembled 2005 OEM transmissions?
Ratios verified via SOA on 11/19/04 and all prices are retail with no discounts:
WRX transmission 32000AG970 $3111.92
3.454 (1st) 1.947 (2nd) 1.366 (3rd) 0.972 (4th) 0.738 (5th) WRX FD 3.90
(Front 3.9 center 1.1 rear 3.54)

FXT transmission 32000AG820 $3111.92
3.454 (1st) 2.062 (2nd) 1.448 (3rd) 1.088 (4th) 0.780 (5th) FXT FD 4.444
(Front 4.44 center 1.0 rear 4.44)
With all the busted/swapped WRX transmissions, it shouldn't be too hard to find a fifth gear out there cheap. The risk is the cost to pull the transmission apart.

FXT manual trannies are the same gearing! Only different final drive.

the cost should be 4 hours or less at any shop, as 5th gear r+r is an in the car repair, you just remove the extension housing (transfer section) from the trans and there 5th is staring at you. i have a spare 5th gear set from a 02 wrx if anyone is willing to give this a try.

not sure about the ratios, seems to be several opinions...time to check the service manuals.

The ratio's are NOT the same, look at the above post closely. The ratio's look different to me, also the Final drive is not going to make the ratio's in the trans. any different(meaning 1-4)

Thank you for the above post. Cliff notes version: FXT gear ratios = WRX gear ratios. FXT FD ratio = 4.44
WRX FD ratio = 3.9
