Hello
The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

Could be either or, or it could be neither. Is the "red light" a transmission temperature warning light? If so, the fluid is over heating and the heat sensor is turning the light on...Check fluid level and the condition of your fluid...if it's off colored and smells burnt, you better have it flushed, refilled and a new filter installed. Heat will kill a transmission faster than anything.
Check the transmission cooler, most montero's had a cooler installed on the front of the vehicle by the radiator...the cooling fins need to be clean, no bugs or debris so air flows through it. Have your vehicle scanned also, if you had a transmission code the computers memory will probably still have it stored, this will be helpful with further diagnosis.

Engine keeps dying after I turn it on.

I had the same problem when I did battery maintenance on my 1988 Montero Sport. The problem was explained to me, that the car's electronic pollution control computer data was erased when the battery is disconnected or the battery totally discharges. The car's computer uses this data to regulate idle speed and other engine factors. The solution given to me was to recheck the battery connections (make sure they are clean, and tighten down), start the vehicle, and just let it sit and idle for about 15 - 20 minutes (without racing the engine or driving the vehicle). This will rebuild and repopulate the car's computer engine data it needs to make adjustments. Hope this helps.
Mark.
