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
