With the vehicle on level ground, chock the wheels, and put the transmission in neutral. Before I replace this park neutral safety switch, also known as transmission range switch, I'm going to spray it with some brake parts cleaner because ours is very dirty and greasy and it'll help me see what's going on.
Disconnect the electrical connector from the switch by pressing in the lock tab and pulling the connector off. It's a little tricky with the 4-wheel drive, the front drive shaft here. I've got this unlocked. It's a little tight in there. I'm going to take a flat-bladed screwdriver and just help pry it off, just very gently until I get it free. There it goes. Okay. Place that aside.
I'm going to use a 15mm wrench and some groove jaw pliers to counterhold the arm. Okay. With that loosened, I’ll switch to a ratcheting wrench. Remove the nut. Then remove the arm. It's a little bit stuck. I'm going to use a flat-bladed screwdriver to pry it off. Okay. This arm is keyed, so it's only going to go on one way. We can place that aside for now.
There is a small mark on the neutral safety switch showing where neutral is. This is why we put the transmission in neutral before taking the lever off. If the lever moves while you're trying to remove it – I'm going to take a little brake parts cleaner and try to clean it off so you can see it better. It's real greasy, but we'll clean it off. If this shaft moves, you can take a 12mm wrench and move it back so the line lines up there. Just like that. That means the transmission is in neutral. I want to remove this switch with the transmission in neutral. Make sure that that line on the black part lines up with the line on the white part.
Now that we have this lined up, remove the 8mm bolts on either side. I want to make sure that these are going to come free using an 8mm wrench. They're free, so I'm going to switch to an 8mm socket and ratchet. With these loose, I'm just going to use my fingers to bring them out the rest of the way. I'm going to reach up, pull the switch off of the transmission selector shaft. If it's difficult to remove, use a large flat-bladed screwdriver or a small pry bar and gently pry it off working all the sides. You need to pry the park neutral safety switch until it becomes free from the transmission selector shaft.
I'm going to use a wire brush to knock off some of the corrosion. This will make installation of the new part easier. You can use brake parts cleaner to clean up any more of the grime.
When installing the new part, line up the keyways in the white plastic with the keyways in the transmission selector shaft. Make sure that this black line on the park neutral safety switch is lined up with the white line on the ring here. That means it's in neutral. This one we actually have to adjust a bit. Adjust it this way, and that's lined up right there, and now I can install the bolts.
Reinstall the 8mm bolts, getting them started by hand. I'll use my 8mm socket and ratchet. Get the other side down. Be careful while you're installing these to not rotate the switch. As I feel these get tight, I'm just going to stop.
We're going to install the shifter control arm. It is keyed to slide over this. You may need to move it a little bit to get it started. Then reinstall the nut using a 15mm ratcheting wrench. Tighten it down. I’ll counterhold the arm with my hand. Hold onto the lever with my hand and then give this a nice tug to tighten it. Reconnect the connector, and the job is complete.

how does this switch unplug?
Press the locking tabs on the wire plug as you pull it away from the old switch.a good spray of wd40 first helps.count the number of pins on plug to ensure you get the right switch. good luck Edgar.
