transmission replacements

"For those contemplating parking their own SVX in the home garage, there are only a few mechanical problems to look out for - transmission wear, noisy wheel bearings and warped discs. It is said that adding a fluid cooler extends transmission life but, in any case, transmission replacements aren't too expensive. It appears that the auto transmission that comes attached to JDM import Liberty twin-turbo motors is very nearly the same as the SVX's and potentially interchangeable - these are often available very cheaply, since most people transplanting a twin-turbo motor usually ditch the auto trans. Note that we've also seen complete JDM SVX half-cuts for $4500."

Is that true? Anyone knows about it?
