Precision replacements for Toyota & Lexus engines and transmissions — done the right way, with factory‑correct procedures and specialist‑level expertise.
When a major component like an engine or transmission fails, you need a shop that understands Toyota and Lexus vehicles inside and out. At Mayo Automotive, we follow strict OEM guidelines, use verified components, and perform every step with dealership‑grade accuracy.
We provide complete engine replacement services for Toyota and Lexus models, including naturally aspirated, turbocharged, and hybrid powertrains. Our process includes:

New gaskets, seals, and critical hardware

Whether it’s an automatic, CVT, hybrid transaxle, or 4WD/ AWD drivetrain, we handle Toyota and Lexus transmission replacements with the precision these systems require. Our service includes:
OEM‑spec fluid and torque specs
Replacement of mounts, seals, and filters (where applicable)
Relearning and adaptation procedures

Warranty options available
We restore smooth shifting, proper drivability, and long‑term reliability.
We use OEM components or high‑quality aftermarket parts based on your needs. Every gasket, mount, sensor, and fastener is replaced or inspected to ensure the engine or transmission is installed to factory standards. Our focus is long‑term reliability and restoring your vehicle to the performance Toyota and Lexus are known for.
Our technicians handle the entire process — from removing the failed engine or transmission to installing and integrating the new unit with factory‑correct precision. Every system is aligned, torqued, wired, calibrated, and verified to ensure a seamless, reliable installation.
Modern Toyota and Lexus vehicles rely heavily on precise electronic control. When the engine or transmission is replaced, updated, or showing performance issues, the ECU and TCU must be programmed and calibrated correctly — otherwise drivability, shifting, fuel trims, and system communication can suffer.
At Mayo Automotive, we use factory‑level Toyota/Lexus diagnostic equipment to perform:
ECU & TCU programming and software updates
Immobilizer and key matching (when required)
Engine and transmission adaptation resets
Live‑data analysis and system verification
Calibration of sensors, throttle body, VVT, and shift logic
Hybrid system communication checks
Every module is programmed, synced, and verified to ensure your engine and transmission operate exactly as Toyota and Lexus engineered them to.
Every engine and transmission replacement at Mayo Automotive is backed by a comprehensive parts and labor warranty. We use OEM or premium components and follow factory‑correct procedures, so we stand behind the quality of our work.
Our warranty covers:
Defects in parts (OEM or premium aftermarket)
Labor associated with the repair or replacement
Proper installation, calibration, and system integration
Peace‑of‑mind support from a Toyota/Lexus specialist
