As it turns out, my mechanic (whom I trust and from whom I bought the car) admitted that despite replacing both the CV joints and tightened up everything under the car he cannot tell for sure what the source of the noise is. In other words, replacing the transmission may not do the trick! :(
Which leaves me still looking for a fix for this problem.
Any suggestion would help so I welcome any and all ideas, however much of a longshot they may be.
