Engine/Transmission (1998.5 - 2002) NV5600 shift at idle problem

[SKneeland]

its probably your clutch master cylinder



mine got so bad i had to start it while in gear



cut the old one out, new one is a two-piece master/slave assembly

I used AMSOIL Manual Synchromesh Transmission Fluid 5W-30 to solve the problem.
