Comprehensive Master Automotive Services
From complete automatic transmission overhauls and custom truck lifts to BG chemical treatments and precision mechanical diagnostics at our Perris, CA facility.
Transmission Service & Rebuilds
Our flagship specialty. Whether you have slipping gears, harsh shifts, torque converter shudder, or delayed reverse engagement, our master transmission specialists diagnose hydraulic pressures, valve body operation, and electronic shift solenoids before recommending rebuilds or fluid flush services.
Mechanical Services
Full-spectrum mechanical auto repair for domestic, Asian, and European vehicles. From cooling system overhauls and thermostat failures to electrical starting/charging issues and engine head gaskets, our technicians diagnose the root cause with pinpoint accuracy.
Precision Tune-Ups
A proper modern tune-up involves much more than swapping plugs. We evaluate air induction, clean throttle bodies, check manifold vacuum, test oxygen sensors, and reset fuel trims to eliminate hesitation and restore factory-smooth idle.
Fuel Injector Service
Clogged or leaking fuel injectors cause uneven cylinder delivery, misfires, poor gas mileage, and catalytic converter damage. We perform direct on-rail cleaning and ultrasonic bench testing to restore atomized spray patterns.
Oil Change Service
The lifeblood of your engine. Every oil service at Master Transmission Technician uses high-lubricity synthetic oil meeting exact manufacturer specifications, plus a thorough 24-point chassis, fluid, and belt inspection.
Brake Flush Service
Brake fluid is hygroscopic and naturally absorbs moisture from the air over time, lowering its boiling point and corroding sensitive ABS valving. Our pressure flush extracts old oxidized fluid and injects fresh high-boiling DOT 3/4 fluid throughout the entire hydraulic system.
Spark Plug Coils & Ignition
Modern engines rely on individual coil-on-plug packs that endure intense thermal cycling. A failing coil creates cylinder misfires (P0300 codes) that shake the car. We test each coil under load and install long-life laser-iridium spark plugs.
Brake Replacement
Dependable stopping power for cars, SUVs, and heavy-duty trucks. We install low-dust ceramic pads and premium rust-inhibited vented/slotted rotors, followed by slide pin lubrication and anti-rattle hardware installation.
Strut Replacements & Shocks
Worn struts compromise braking distances and stability in emergency maneuvers. We install complete pre-assembled strut units featuring new springs, mounts, and dampening cartridges, restoring that firm, factory-new road feel.
Truck Lifts & Leveling Kits
From leveling the factory rake on half-ton pickups to installing comprehensive 6" to 8" suspension lift systems on heavy-duty diesel trucks. We engineer correct driveline angles, install extended brake lines, and calibrate steering components for highway manners.
BG Oil Treatment & Engine Protection
Modern direct-injection and turbocharged engines operate at higher cylinder temperatures, causing oil breakdown and carbon buildup. BG MOA® fortifies all brands of engine oil, preventing piston ring sticking, oxidation, and oil consumption under extreme towing or desert heat.
4x4 System Service
Keep your four-wheel drive ready for mountain climbs or desert trails. We service manual and electronic transfer cases, inspect shift motor actuators, service CV axles, and replace worn universal joints to prevent catastrophic driveline failure.
Differential Services
Differentials endure brutal torque loads. We remove differential covers to inspect tooth contact patterns on the ring and pinion gears, clear metal filings from magnetic drain plugs, install fresh gaskets, and fill with high-grade synthetic gear lube plus LSD friction modifier.
Authorized BG Protection & Certified Warranty Work
Every transmission rebuild, brake replacement, and BG fluid flush is performed using professional-grade tools and parts meeting or exceeding OEM tolerances.

Frequently Asked Questions
Everything you need to know about our transmission diagnostics, BG care, warranties, and shop visits in Perris, CA.
Common symptoms include delayed engagement (when shifting into Drive or Reverse takes 2–4 seconds before engaging), high-rev flaring where the engine revs up before shifting, harsh clunking gear transitions, transmission temperature warning lights, or a burnt smell resembling dark maple syrup. If you notice any of these, bring it in immediately—catching hydraulic pressure loss early often saves the transmission from requiring a full rebuild.
