1. Look for the identification tag:
* Transmission Case: The transmission itself might have an identification tag cast into the case. This tag will usually have a code that corresponds to the specific transmission type (e.g., M5OD, etc.). This is the most reliable method, but it can be difficult to access depending on the vehicle's condition and undercarriage protection. You might need a flashlight and possibly a mirror to get a good look.
* Engine Compartment: Check the engine compartment for a sticker or plate showing the vehicle's specifications. This might include the transmission type.
2. Check the owner's manual: If you have the original owner's manual, it will clearly state the transmission type.
3. Check the Vehicle Identification Number (VIN): While the VIN itself doesn't directly state the transmission, you can use it to look up the vehicle's specifications on sites dedicated to vehicle history reports (like Carfax or AutoCheck). These reports often detail the transmission.
4. Examine the transmission shifter:
* Number of gears: Count the number of forward gears. A 5-speed manual will have five, while a 3-speed automatic will have three positions (P-R-N-D-L). The number of gears is a strong clue, but not always definitive because there were some variations in both manual and automatic transmissions.
* Shifter pattern: The pattern of the shifter can provide hints. A 5-speed manual typically has an "H" pattern or a similar configuration. A 3-speed automatic has a typical pattern with Park, Reverse, Neutral, Drive and Low.
Common Transmission Types in 1986 Ford Ranger 4x4:
The most likely transmission types for a 1986 Ford Ranger 4x4 are:
* Manual Transmissions: M5OD (5-speed manual) was common. There might have been some variations or earlier 4-speed units, though less likely.
* Automatic Transmissions: A 3-speed automatic transmission was likely.
Important Note: Without being able to physically see the transmission or access the vehicle's documentation, it's impossible to definitively state which transmission is in your specific 1986 Ford Ranger 4x4. Use the methods above to identify it. If you can provide a picture of the shifter and any visible markings on the transmission, it may be possible to give you a more precise answer.
