Question about Cars & Trucks
I was towing a boat on the interstate and heard a loud screeching sound/grinding sound and thought i blew out a tire on the trailer. Immediately pull over and find nothing wrong with trailer so i inspect the undercarriage and engine bay, but saw nothing visibly wrong as well as no noise. Continued driving and probably got about 15 miles and noticed something that sounded like some kind of metal slapping the spokes on a wheel coming from directly under the center console. It would speed up as i sped up and vice versa. No warning lights on the dash and the Transmission temp was normal. Pulled over again, nothing. An hour or so later it got really loud, more like a screeching/grinding noise. This continued for another 20 minutes before i got back to my shop and we checked fluid levels and inspected the undercarriage thoroughly. The Transmission was bone dry. I have added transmission fluid but the noise is the same. My instincts tell me that the transmission is done for, but the truck is DRIVING NORMALLY! No change in performance... just the noise. Ill be bringing it in to the dealership soon but id really like to know what you might think it is.
Check all the back plates at the back of the wheels Stones can get stuck in there and rub the discs as you move along, if the wheel is removed you will see a plate that keeps stones and dirt of the irear part of the brake disk.or rotor .

SOURCE: grinding noise while driving.
a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline
b) pebbles stuck between the disc shield and the disk
c) dried out wheel bearings
d) worn Universal Joints in the drive shafts
e) worn A/C pump
f) worn alternator
g) worn water pump
Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.

You didn't specify if your vehicle is 2- or 4-wheel drive.
If 4 wheel, you may have a failing contstant velocity joint which, when having developed worn spots in the cage can cause the noise you describe.
Typically, turning the wheel back and forth can cause the noise to become less or more loud and often the combination of a specific speed and driving a certain curve radius can cause the noise to nearly disappear or become more pronounced.

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.
