whats the difference between gearbox codes for newage boxes?

mine is TY754VN2AA

but I have seen TY754VN6AA, TY754VN5AA, TY754VN4AA, TN754VN1AA, TY754VG7AA etc etc

are they the same gearbox, but off different year cars?

mine is a 2001 bug, and I think I may have broke it

cheers!

Google the numbers there is a PDF file about on web which states what gearbox is for what.

There are 5 basic versions
4 in 6 speed and looks like all shared the 5speed but updated for 2.5ltr models ISH

6sp UK/Euro non dccd 2002-2004
6sp UK/Euro dccd 2005 onwards

6sp JDM non dccd 2001-2003
6sp JDM dccd 2003 onwards
Then some of these versions have helical front LSD and others have suretrac Front LSD

5sp 2.0ltr
5sp 2.5ltr

IIRC the WRX 5speed has no front LSD

Although past that will be the year the box was made.


JDM has different ratios as 8krpm compared to. UK euro 7krpm

Iirc IMHO

Type in google "subaru gearbox codes"

It will give you link to a PDF table of all gearboxes

Yours is a 2001 WRX 5speed by the look of it
