What Transaxle Do I Have?

[MDAY69]

I found the stamp on the underside of the transaxle just behind the axle shafts, but it is stamped "EFD 0849". Does this mean anything to anyone?

This got me curious enough to pull my G86 out of the back of the garage and take a look. I could not find G86xxxx.... anywhere. I did find an "EFD 16011",
then I looked in my Service Manual 'Group 3, Transmission, Manual Transmission' and figured it's a G86/01 made on January 16th 2001.



Yours is a G86/01 from April 8th 1999. (...and bell housing, EFD10020: Feb 10th 2000)

That is very interesting information. Thanks for your efforts. At least I now have something to go on.

Thank you for the helpful diagram. There are numbers and codes scattered all over the 6 speed transmission.They are hard to see on the car but I have 2 on the bench now so have a little guide to what may be significant numbers from mine.This may help others know where to look.Some of these may be part(Getrag?) numbers.
First - I found nothing on top of the Bellhousing -as shown in the diagram above so perhaps that applies only to older or 5 speed gearboxes??.
1.Underneath the trans , just behind the axle shafts ,on the same side as the shifter,just by the lower counterweight = G86201031713. This is the important #
2. also on the shifter side just beneath the axle shaft = Getrag Made in Germany 256.0.0102.91
On the opposite side
3. on the side of the gearbox case = +GF+WD 21561
4. underneath the axle shaft = 4571.1..1./02
5. by the clutch bellhousing = 292.0.0168.90
This is from the newer of the 2 transmissions I have on the bench.
If anyone can decipher all these numbers ,it would be interesting.
And as far as I have read , the Boxster S did not have LSD, not even an option but could be retrofit - see link below:No not even option # M224 ?

JFP will correct any mistakes I hope:-) because I am not an expert on these transmissions.

.

The S model section of the manual shows the model info is on the bottom, behind the output shafts. (as described above)

Decoding:
G8620 -Transmission type (6 speed)
1 -Index for version (1= normal differential, NO OTHER Index is given).
031713 -Serial number.

This helps others find the easily located number and ignore the rest of the cryptic numbers all over the transmission . Underneath the car on jackstands ,this could be a tedious exercise otherwise.
