Subaru Transmissions

Intro

Following on from the successful list of Subaru Engines, I have compiled a short list of Transmissions from Subaru …

Do Note : I've used references from Wikipedia, AUSubaru + others on here to compile the list.

For ID purposes, there is usually a sticker or part number stamped on the box …

Index

I've broken them down into the following categories :

  • Auto Trany's
  • Manual Trany's
  • Other Trany's
  • Rear Diff's

Generally - I've shown the 'index' code for each type of box & what it went into from factory.
( There are too many variants to show 'em all )

Feel free to suggest any that I've missed or corrections to be made …

Notes : This is a work in progress
