For me, the best 2nd gear bark came with my old GN with a stock trans, sonnax super servo, and with the TV cable set back a notch or two to increase line pressure. When the trans was swapped with a built trans and converter, shifts were quick and firm but the 2nd gear chirp was gone. Instead, it just continued to shred the tires in 2nd if I stayed into it. Same with the trans I have now in my Limited. Shifts quick and firm and is much better than a stock trans but it doesn't have that hard 2nd gear bark.
