Could be a number of reasons... air line which actuates the range selector might not be working, could be a bad shaft in the transmission.... you'd have to give a more thorough diagnosis in order to narrow it down. We'd need to know if the range selector switch will even flip up or not, and what happens when you try to shift into high range. If you've had the transmission serviced recently (especially if you've tried to DIY it), that would be pertinent to know.
We have repaired air lines 4 times with the final time we replaced those lines. We also replaced shifter. When I try to shift into high range, just get a severe grinding and have exhausted any ideas?
No you can not, it is a different transmission. The 18 speed has a splitter for the lower range as well as high range.
9 speed doesn't have a gear splitter, just the range selector.

The ideal RPM range depends on your engine, and the speed depends on your transmission gear ratios, rear end gear ratio, and tire revolutions per mile.
Yes, there's a transmission filter.
50W if synthetic, 80W is mineral.
The Nissan stanza has a 4-speed auto transmission. It shifting is electronically-operated . The transmission computer box is located in the center console. It is next to the ECM box.
Either a proprietary Mack 18 speed or an Eaton-Fuller 18 speed. Various models of the Eaton-Fuller were available, from 1600 torque to 2100 torque.
I've never heard of an Eaton Fuller 12 speed, nor am I able to find any references to one via Google. I've driven Eaton Fuller 8LL, 9 speed, 10 speed, 13 speed, and 18 speed transmissions - could you be thinking of one of these? IIRC, Volvo marketed a proprietary 12 speed transmission, and Meritor offered a 12 speed automatic, but not Eaton Fuller.
Depends on the final drive ratio.
................2...............4---------------6/7...............10/11 1..............3...............5---------------8/9------------12/13 ................low range......................high range with splitter on each gear
No, 10 speed does not convert over. You would need to get a truck with either a 13 speed, or a 9C transmission (which is convertible).
