Hi guys,

I've got a 02 imprezza ts and I have a 03 legacy gt tranny ( both trannys are manuals) can I use the gt tranny? Are the rear end ratios the same?

Also are the clutches the same push vs pull.

Any insight would be helpful as my 4 th gear is shot!????

Thanks!

Ratios might be different, but I think the GT and RS use the Same 3.90 ratio as the Impreza, but either or might also be 4.11

 

A call to Subaru with trans codes might clear it up

Google the trans codes as the GTs were not always consistent to my knowledge. There's a chart out there to look it all up if you do a search or two on here, it should turn up.

 

They will have the same style clutch.

Thanks bud,

Did call they have diff codes but I've also got a couple of subie techs that swear it will bolt right in and the rears are the same agh!

Here's the chart.

Thanks that's huge!

I'll check it out and I'll let you all know the end result!

Looks like you'll need to swap the rear diff and they both should be PUSH style, as are all Subie NON-turbo* clutches -both cable and hydro - hydraulic. * some turbo'd Subies are Push; some are Pull.

 

 

 Just look. If the clutch slave is mounted behind the fork, you have a pull-type. If it's mounted in front of the fork, you have a push-type. Another way to tell is to look around the fork. If there is a cap with a spot for an allen wrench, it's a pull-type. Otherwise, it's a push type, e.g. 

In general, If the slave pushes towards the firewall, it's a push type. If it pushes away, it's a pull type.

Matches the Tranny Chart linked by 'AdSub'

 

The trans code (on the bell housing - TY********) MAY tell you - if you can find a 'decoder', but not sure.

Thanks !

Great now I have to find a rear diff!????

Oh well gotta love the simplicity!

Thanks again

the GT rear is a 4.11 ratio.

and was /is a vlsd, locking diff.

 

so a rear diff from an outback or GT, 01 - 03, H4, manual trans will match and be locking.

a forester manual trans will match the raio, i do not know if it is locking.

 

but the rear diff from an impreza (not wrx) auto trans or lego L, brighton, or LS auto trans 00 - 03 will also work, just not locking.

for that matter, any rear diff from and auto trans car lego 95 - 99 with ej22 engine,

or any 93 - 97  auto trans impreza with ej22 or ej18.

 

lots to pick from.

sort by zip code, shipping will be expensive.

^....be aware that the BOLT pattern on the pinion flange (front for rear diff) changed around '95 - Legacy for sure, probably on Imprezas too- , so the drive shaft / line won't bolt up properly.
