I think this is one of the better discussions on the Lexus transmissions, and I hate to dumb it down with less technical issues, but what exactly is the problem(s) with the Lexus transmission, particularly in the AWD? I've read many of the posts on this site concerning issues of overheating, faulty filters, slippage, etc. But what has caused all of this? Lexus, of all car builders, must have known how to properly build a transmission. How did all of this happen?
And specifically for Cardona6569, you mentioned several products for slipping and overheating transmissions (e.g. TransX, Slick 50, and Towkool). Can you elaborate a little more on these products, and where could I get them? My transmission always hesitates in the morning, when the tranny is cool. It won't shift from 2nd 3rd gear until RPMs climb above 3,000. But other than that, I don't seem to have any problems with the tranny. Which product would you recommend??
Thanks.
