Nissan offers 3 transmissions for the Fronty. The FS5R30A (5sp manual), FS6R31A (6sp manual), and RE5R05A (5sp auto). The 6sp is only avail behind the 4.0L VQ, the 5sp is only behind the 2.5L. The auto is behind both.Not to high jack thread, but I have a related question. Is the 5 speed auto used with the 2.5 the same as the one used with the V6? Or is it weaker?
