Hi there! I've just gotten a 1996 Ford Ranger 2.3l with 240k miles about a week ago, I got it by trading one of my flat screen TV's.
When inspecting the truck for the first time, it ran good, I took the trade and drove 120 miles back to where I live. It drove great, no issues it running at all.
A week later, I changed the engine oil and filter (Mobil-1 Synthetic 5w-30), I took it out and as I was going down the freeway ramp (I was in 3rd gear about 6k-8k RPM), I suddenly heard a popping noise and sounded like it popped out of gear so I quickly shifted into 4th gear and took the upcoming exit.
After taking the exit, I could not shift into 1st, 2nd or 3rd gear and was only limited to 4th, 5th and reverse. I drove about 4 miles home in 4th gear.
Now when I got home, I tried through all the gears and reversing, the truck is slow when letting out the clutch in 4th and 5th and a strong smell of something burning (possibly clutch). When I put the truck in neutral and I let go of the clutch, it seems as if the truck is still in some gear...
Before this happened, I've also noticed a rattling noise when putting the truck in 1st and 2nd gear even when the clutch is engaged. The engine still runs great! Will start up no problem to this day.
I am not sure if I did something wrong while changing the oil and filter, this is the first Ford truck that I've owned and did many other oil changes on my other vehicles. I will take pictures of the drain plug where i drained the engine oil. (I put 4 quarts in). I'm 80% sure that I did not drain the tranny fluid lol.
Please reply to this thread if anyone has any information or help on this topic! Thank you!!
tldr; Got the truck, went down freeway ramp in 3rd gear about 3-4k RPM, truck popped out of gear, will no longer shift into 1st, 2nd and 3rd gear. Truck seems to be in a gear even when put into neutral.
