Howdy, folks, I plan to have my A140e trans (factory 5s 4-speed auto) fully built by IPT in the next few months, and while they're in there it would be a good time to swap the final drive gears to the shortest ones available, which as far as I know is 3.94. Does anybody know how I can verify what the final drive ratio in my current trans is? I want to gather all the parts in advance, but I don't want to buy 3.94 gears if I already have them, of course. I'd ask my dealer, but they have been pretty clueless about this stuff in the past.

thanks for any help.

Anybody???
