Transaxle final drive ratios
ZF made the transaxles for Alfetta's, GTV-6's and Milanos. I recently put a Twin Spark in my Alfetta and the transaxle is geared so low that I'm spinning 4,000 at 80 mph. I have 195/60/14 Bridgestones on it. Yes, theyare slightly lower profile than the stock tires. Which transaxle has the tallest rear end ratio? Thanks!

Milano Verdes came with a 3.55:1 ratio, and 1982-83 GTV6s came with a 3.42:1 ratio. Both of those are very tall and should provide the relaxed cruising you are looking for, although only the Verde box will have LSD standard.

Are the LSDs identical? Is it possible/practical to put the Verde LSD into a 4.1:1 ratio box from a Silver or Gold? That would make it a bit easier to outfit the Verde with the 'preferred' setup.

The LSD unit itself is identical. Properly setting up the pinion is not trivial. I know of a few people who have done this, both very experienced mechanics with specialized tools. Even they didn't get it right the first time.

LSD into another LDS box should be quite easy in comparison.

how do you tell the Verde from the Platinum LSD. I have one of each I believe but do not know how to tell them apart.
