Most rebuilds take three to five days, depending on parts availability and the complexity of your specific transmission. Rush service is sometimes available for an additional fee.
If the rest of your vehicle is in good shape and the repair cost is under half the vehicle’s value, rebuilding usually makes sense. We walk through your options honestly.
Low or contaminated fluid is the number one killer. Regular service intervals and catching leaks early can prevent most catastrophic failures and extend transmission life significantly.
