wow I didn't think it would be that much. Ya it's definitely not overtightened then. The noise is a whiney type of metal grinding noise.. It's most noticeable in 5th but it also does it in 4th however it's only while accelerating. My G-52 did the same thing in 3-5th, I figured the bearings were just starting to go out but now I'm not so sure.. Do these transmissions usually make noise?? I haven't noticed it in the past few years of owning my toyotas but maybe I just missed it??
