Hi there although i'm new i've been reading these forums for some time and find it a very good read i was just wondering if a gearbox i,ve just bought will fit mine i have a 04uk wrx with a ty754vn5aa and i've bought a 2004-05 ty754vn6aa it on its way to me, and do i need anything to fit it [ i.e shafts, new mounts etc] thanx.

when you put a diffrent coded gear box on you probably will need the rear diff to match the ratios, needs cheaking anyway i would of thought

 

I'm guessing that'll fit, but it's a 6-speed box instead of 5.

 

Try this, The SPDA - Transmission Chart

Then you need to call Welcome to the API website

 

The 6AA is a UK box the same as the 5AA so you should not have any rear diff issues they are both 3.54 it is from the early 2.5lt WRX's. You will need new drive shafts as this box does not have the stub shafts coming out of the box as in the other 754 and 752 boxes. This box requires the male ended shafts. Pic below of the 7AA but the shafts on the 6AA are the same.



This is the best of the 5 speed boxes and the strongest one so far.They have been holding up well with cars producing over 400lbs ft, it has been reengineered as can be seen from the casing which is significantly wider around the drive shaft output area. Good choice of replacement. You may struggle to get shafts though I did it took nearly 3 months to get a set at a decent price and then found the box I had was a 7AA which uses a pull clutch set up - bummer. Hope this helps

 

thanx, i've now seen the same code as mine for sale in a local yard so if i get a decent offer for mine i will buy the correct 1, so heres a chance for 1 of you guys with more bhp than i've seen horses to get a strong box thats only covered around 30k, i only own a standard wrx so not really needed thanx. send me your number if your intersted thanx. ty754vn6aa
