George - The Platinum transaxle is lsd. However, it has 4.10 gearing.

I was told that I had a Verde transaxle in the car (the transaxle was changed-out by a previous owner at approximately 90K miles. The invoice for that work says "Milano Verde" on it), but I now doubt that. I doubt it for two main reasons. First of all, My car seems to have a stock GTV-6 speedometer sending unit, and I've been told that the GTV-6 Speedometer sender won't fit the Verde transaxle case. Secondly, the Verde has limited-slip differential, but when I have had my car on a lift and spun one of the rear wheels, it acts like a non- LSD rear end. So, my feeling is that if, indeed, my car has a rear-end out of a Milano, it's a Platinum model, not a Verde and unless the mechanic who did the work reworked the mount for the Speedo sender, it's not a Milano transaxle at all.
