1. Diagnosis: The first and most crucial step is accurate diagnosis. This requires identifying the specific transmission problem. Symptoms can include:
* Slipping gears: The car doesn't engage properly in a gear, or it slips out of gear.
* Hard shifting: Gears engage with a noticeable jolt or grind.
* Noisy transmission: Grinding, whining, humming, or other unusual noises from the transmission.
* Inability to shift: The car won't shift into certain gears.
* Leaking transmission fluid: Low fluid levels can lead to serious damage.
A mechanic will need to inspect the transmission, likely including:
* Fluid inspection: Checking the fluid level and condition for signs of contamination or burning.
* Road test: To observe shifting behavior under various conditions.
* Possibly a scan: To check for any transmission-related trouble codes.
* Manual inspection of linkage and components: In some cases this is done, or the transmission pan might need to be dropped to assess the condition of the transmission filter and fluid.
2. Repair Options: Depending on the diagnosis, repair options vary widely in cost and complexity:
* Fluid and filter change: This is the simplest and least expensive repair, addressing minor issues or preventative maintenance. However, it won't fix major internal problems.
* Repair of specific components: If a particular component (like a solenoid, shift cable, or seal) is faulty, it may be possible to replace it. This is less expensive than a full rebuild or replacement.
* Transmission rebuild: This involves disassembling the transmission, inspecting all components, replacing worn or damaged parts, and reassembling it. This is a labor-intensive and expensive process, requiring specialized tools and knowledge.
* Transmission replacement: In cases of severe damage or when rebuilding isn't economically feasible, replacing the transmission with a used or rebuilt unit is an option. This is typically the most expensive solution.
3. Repair Process (General Overview – NOT a DIY guide): A transmission rebuild involves:
* Removal of the transmission: This requires specialized tools and knowledge.
* Disassembly: Carefully taking apart the transmission to inspect all internal components (gears, clutches, synchronizers, etc.).
* Inspection and assessment: Determining which parts need replacing.
* Replacement of parts: Sourcing and installing new or remanufactured components.
* Reassembly: Carefully putting the transmission back together.
* Installation: Reinstalling the transmission in the vehicle.
* Testing and adjustment: Checking the functionality and making necessary adjustments.
Important Considerations:
* Cost: Repair costs can range from a few hundred dollars for a fluid change to several thousand for a rebuild or replacement.
* Expertise: Transmission repair is highly specialized work. Attempting a DIY repair without the proper skills and tools can lead to further damage and increased costs.
* Used vs. rebuilt transmissions: Used transmissions are cheaper but carry higher risk of premature failure. Rebuilt transmissions offer better reliability but are more expensive.
In summary: Do not attempt to repair a Honda Prelude transmission yourself unless you have extensive experience with automotive transmissions. Always consult a qualified mechanic for diagnosis and repair. Get multiple quotes if possible to compare prices and ensure you're getting a fair deal.
