I'm new here am will post an intro soon but I did have a question about my new truck. It's 100% stock cept for the SCT TSX I just bought for it. It has 130k and has the Auto tranny. With the programmer, I played with tunes. Mainly Performance and Street. I actually then ran it at our local track and ran a 14.99 spinning well into 3rd. It has left a posi patch but it's extremely rare to spin both tires. Earlier, I posted it up for trade for a posi but then learned that the door tag does show the ID. It's listed as :C1 which then shows a 3.73L The "L" Stand for Limited slip/posi. do the clutch packs go out on this after time? I also found two tags on the rear end cover.

One shows: L7310 5 3A15,
the other shows: 15w140 synth only.

The center section shows: V 423 F


Do I have a posi?
