Does clutch feel ok? Grinding in reverse usually indicates a clutch problem.

Grinding sound

Is the knocking sound when the car is moving or sitting still as well? Does the grinding sound happen just as you put the car into reverse or does it keep grinding?
These transmissions are very problematic, especially if they are not properly maintained. The most likely candidates are a cracked flywheel or a broken drum inside the transmission. Either way, it sounds like the transmission will have to be removed to pinpoint the problem.

I have a 1999 Pontiac Sunfire. Transmission is going out I think. When I put it into reverse it's sometimes goes into reverse and sometimes doesn't but I hear a loud knock. fluid is right and not...

putting it into a gear and hearing a knock indicates that the engine mounts or transmission mounts are broken
naturally if you put it in neutral it will not move as that what neutral is
perhaps the neutral position needs adjusting as it may still be in drive
have the fault codes read to determine any sensor/servo/solenoid faults before spending big money on a transmission

Auto transmision grinds in reverse, put in dr grinding stops but doesn't move

sounds like it is time to get the transmission rebuilt. usually when they go out you will only have reverse. It sounds like the oil pump has exploded inside the trans. sorry for the bad news

4x4 low range will not disengage.

You need to put the vehicle in Neutral, foot on brake, and then turn the Selector to the other 2 positions that you want.

If you have done this and the vehicle does not change gears, try shifting into Reverse and moving the vehicle slightly, then try the Neutral procedures again.

If this still fails to work, the problem is a mechanical component. There is an Electric Servo which uses a single feed wire from the dash Selector. The feed wire carries 3 different Voltages which moves the Servo 3 different positions. The Selector on the dash has the resistors and if bad will not send the correct Voltage to the Servo. The Voltage can be measured at the feed wire.

The other possibility is the Servo is stuck. This is why my second recommendation was to shift to Reverse, which was an attempt to unload pressure on the Servo stem, to free it.

I hope my solution is helpful in solving your problem.

Grinding when in reverse and tries bogging down at lights

stop shifting so hard. your reverse gear is the same exact gear as your first, so if you shift hard and grind that gear a little then reverse will be harder to get into. you probably need your transmission rebuilt the harder your engine has to work the more its going to bogg down
