why has my nissan 2003 transmission failed

Question

when i drive, the gear does not transmit from the first level so the engine is noisywhen i am in motion. The caralso have poor idle problems.. goes high and low continously.

Answer 1

what code do you have? the transmission fluid should be replaced every 30k miles or so

if you have never replace the transmission fluid that is probably the number 1 cause of tranmission problems
