What Transaxle Do I Have?

[911monty]

I just went thru this exercise while ordering parts (axle flange) on an recent output seal change I did. The first three letters are the model type and are critical to find the correct internal part. My trans is the CWA. Attached as an example is a page from the parts manual I searched.

Well This is the page I meant to post.

Here are two links to the relevant parts pages that are searchable.
Where did you find any markings on the gearbox that relate to :
CWA/DVY/EFD classification letter GDW/GFW ?
see post #3 above for locations:
" on the side of the gearbox case = +GF+WD 21561" What does this mean?

If you want to know if the gearbox has a LSD in it, turn one of the axle flanges, if the other one rotates in the same direction, then YES you have LSD, if it turns in the opposite direction then NO you have a open differential.

If you happen to need a LSD, give me a call. I have a excellent option for you. .

Happy to help,

Erik;
That is useful info because one of the 2 transmissions I have is missing the diff and output flanges.
2 options Porsche missed on the Boxster S - ventilated seats and a 'real' LSD.

Hey Gelbster sorry if I didn't understand but are you asking about the above questions?

To the OP, I'd have to go check but I believe the EFD on your trans signifies it as from a 2.7 liter and it has a different gear ratio than the 2.5 trans.

edit: Yep. Your EFD axle has 32 tooth ring gear and 9 tooth pinion for a 3.55 ratio. The CWA/ etc for the 2.5 have 35/9 for 3.88 ratio.
