The choice between repairing an existing automatic transmission and installing a contract (used) automatic transmission depends on several factors:
Repair of existing automatic transmission
* Advantages:
* Retaining the original transmission that may best suit the specific vehicle.
* Possibility of eliminating specific faults, which may be more cost-effective than replacing the entire transmission.
* Sometimes you can find highly qualified mechanics to repair automatic transmissions.
* Flaws:
* Repairs can be expensive, especially if large components need to be replaced.
*Repair time may be long.
* No warranty on refurbished gearbox.
Contract automatic transmission
* Advantages:
* Usually cheaper than repair, especially for large and complex transmissions.
*Replacement usually takes less time.
*If you are on a limited budget this may be the only option.
* Most contract automatic transmissions come with a warranty.
* Flaws:
*Difficult to find gearbox in good condition.
*May require modification to fit specific vehicle.
*Mileage and service history of contract transmission may not be known.
Factors to consider:
*Cost: Repair costs may vary depending on the type of fault and the need to replace major components. The cost of a contract transmission depends on its condition, mileage and availability.
* Time: Repairs can take several weeks, while installing a contract transmission usually takes several days.
* Warranty: Rebuilt automatic transmissions rarely come with a warranty, while most contract transmissions come with a warranty (usually 3 to 12 months).
* Mechanic’s qualifications: The qualifications of a mechanic to repair automatic transmissions are of great importance. Experienced and reputable mechanics can provide better repairs and increase the likelihood of successful repairs.
* Service History: If the vehicle’s service history is available, it can provide information about potential problems with the automatic transmission and help in making decisions about repair or replacement.
Result:
In general, if your budget allows, having your existing automatic transmission repaired by an experienced mechanic is the preferred option. However, if the budget is limited or repairs are too expensive, installing a contract automatic transmission may be a reasonable solution.
