[98-4dr]

I have a 98 Sentra SE. While driving the other day, I pulled out of the driveway and gave about half throttle and about 50 yards into first gear, the motor revved freely and tached out. I shifted into second and nothing. The clutch cable is fine and it appears that the clutch and pressure plate are fine because I still have normal pedal pressure.Also, it shifts into all the gears fine, just no power to the wheels. I think it could be either the input shaft being sheared or possibly the left drive axle (98 and 99 sentras did not come with LSD's). NEED HELP!

will a tranny out of a 93 SER work seeing how they are both SR20's? What about Axle lengths seeing how the 93 had a LSD?

Thanks!!!!!!!!!!!!!!!!!!!!!!!!
