help!!! Isuzu NPR

1993 Isuzu NPR- Sometimes it won't shift out of low gear and at times it won't shift into gear. What could be wrong?

Clutch cable or hydraulic? Might need to be bled or adjusted. Might also be a tranny problem. But check the clutch first.

Actually you didn't say if it was auto or not and I think those ones are. Get the tranny checked in that case. might be something as dumb as low fluid.

thanks it is an auto
