Transmission Repair at NewGen Auto Repair
Signs of a transmission problem include engine RPM flaring between gears, a delay when you shift into drive or reverse, harsh or late shifts, a burning smell or red fluid under the car.
The first step is always checking the fluid level and condition and reading the codes — some problems are fixed with a fluid service, a sensor or a solenoid instead of a whole transmission.
Mechanical repairs come with our 24-month / 24,000-mile warranty on parts and labor†. Extended warranty claims welcome.

How do I know if my transmission is slipping?
The engine revs up but the car doesn't speed up as it should, shifts feel delayed or harsh, or the car jerks between gears. Read more in our article on transmission slipping signs.
Do I always need a new transmission?
No. Many problems come from low or old fluid, a sensor or a solenoid. We diagnose before recommending replacement.
Is transmission repair covered by my extended warranty?
Often yes — internal transmission parts are usually covered. Bring your contract and we'll handle the claim.

*Deductible assistance of up to $1,000 is available only on insurance claims where your insurance company has approved a repair amount of $8,000 or more and the repair is performed in accordance with that insurer-approved estimate (California Penal Code § 551(b)). We never increase a repair estimate to cover a deductible. Not available on customer-pay repairs. Ask us for details before your repair begins.
**Free computer diagnostic scan: we read and explain your vehicle's trouble codes at no charge, no purchase required. If the problem needs in-depth testing (labor), we give you a written estimate and get your approval before any paid work, as California law requires.
†Warranty: limited lifetime warranty on our collision, body and paint workmanship for as long as you own the vehicle; 24 months / 24,000 miles (whichever comes first) on mechanical repairs, parts and labor. Not covered: normal wear, new damage, abuse or neglect, rust or chips from road debris, and customer-supplied parts. Warranty terms are written on your invoice.
‡Accident towing: you pay nothing out of pocket when you have collision coverage or the other driver is at fault — we pay the tow and bill the insurance company. If no insurance covers the tow, we tell you the price before the truck is sent.
