Ok...I had to pull out my Skyline bible to set the record straight.
M-Atx (4 spd Auto) = 250gt, 250GTm
5M-Atx (5spd Auto) = 300GT, 250GT Four, 350GT Coupe & Sedan
CVT-8 = Only 350GT8 sedan
6Spd Manual = 350GT sedan & Coupe
Reference (Hyper Rev Vol 89)
I've got a 300gt and 350gt sedan, both are 5spd Autos. I assume Easy Tiger has the 4Spd Auto in the 250gt.
