The synchros are going out on the tranny
Depending on the transmission type, the neutral safety could be located in several places on the transmission. If the switch is bad, the Rodeo could either start in any gear, or not start at all.
80/90 gear lube
Could be in the trany sensor/gear or the speedo itself
I am not a transmission expert just a Rodeo Sport owner and this is the problem we had and to fix our problem it was the (Battery) not enough power going to computer to transmission which detected a short in the electrical to the transmission and to save the computer the car it shuts down the transmission, so get a new battery before taking it to transmission expert, might not cost as much as our experiment to detect the problem by the hour charge.
Yeah just make sure you have it in neutral. I've heard of people leaving a manual transmission in gear and trying that and actually blowing up the transmission.
You have to remove the timing belt to get at it if it's a v-6 Not an easy task If it's a four cyl you need a special tool to hold the pump gear or you will have to take the chain apart
There is no overdrive, per se, but a mode switch called "Power Mode" that doubles as an overdrive, allowing more RPMs per gear.
U/S=up shift...if you have a manual transmission, you'll find that you won't see it come on once you get to 5th gear. Below 5th, it's tell you when you reach recommended shift points.

I have the same problem with my 98 Isuzu Rodeo. If you haven't already, replace the Idle air control valve. I have the same problem with my 98 Isuzu Rodeo. If you haven't already, replace the Idle air control valve.
