This is a general overview, and specifics will vary depending on your Ranger's engine and transmission type:
1. Preparation:
* Safety First: Disconnect the negative battery cable. Support the vehicle securely on jack stands. Never work under a vehicle supported only by a jack.
* Gather Tools: You'll need a variety of tools including sockets, wrenches (metric and possibly SAE), a transmission jack, a torque wrench, pry bars, and possibly a clutch alignment tool. Consult your repair manual for a comprehensive list.
* Fluid Drainage: Drain the transmission fluid completely.
* Disconnect Components: Disconnect the driveshaft(s), shift linkage, speedometer cable, electrical connectors, and any other components connected to the transmission. Take pictures as you go to help with reassembly.
2. Removing the Transmission:
* Support the Transmission: Use a transmission jack to support the transmission's weight. This is crucial to prevent damage and injury.
* Remove the Bellhousing Bolts: Carefully remove the bolts attaching the transmission to the engine.
* Separate the Transmission and Engine: Slowly and carefully lower the transmission using the transmission jack. There might be some resistance; use pry bars carefully and avoid damaging components. You may need to maneuver the transmission to clear the engine and bellhousing.
* Remove the Transmission: Once clear, carefully move the transmission out from under the vehicle.
3. Post-Removal:
* Inspect Components: Inspect the clutch (if applicable), flywheel, and input shaft for any wear or damage.
* Clean: Clean any mating surfaces thoroughly.
Important Considerations:
* Clutch: If you have a manual transmission, the clutch will need to be removed and replaced or inspected for wear. This adds considerable complexity to the job.
* Torque Specifications: Follow the torque specifications in your repair manual precisely to prevent damage.
* Alignment: If reinstalling a manual transmission, you'll likely need a clutch alignment tool to ensure proper alignment of the clutch disc and input shaft.
* Professional Help: If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic. This is a complex procedure and mistakes can be costly.
This is a highly simplified overview. Always consult a repair manual specific to your 1988 Ford Ranger for detailed instructions and torque specifications. Improperly completing this job can cause significant damage to your vehicle and potentially lead to injury. If you are unsure about any step, seek professional help.
