Engine and Transmission Replacement in Sun Valley, CA

It depends on the unit and your vehicle. A used transmission often runs $800–$2,500, a rebuilt one $1,800–$4,500, a remanufactured unit $2,500–$6,000, and a new OEM transmission $4,000–$12,000+, with labor on top. For a common vehicle, total replacement typically lands somewhere between $3,000 and $8,000. As an example, a transmission for a GMC Sierra 1500 generally falls in the mid-to-upper part of that range, depending on whether you go used, reman, or new. We'll give you an exact quote after assessing your vehicle.

A used or rebuilt engine generally runs $1,500–$4,500 installed, a new engine $3,000–$7,000+, and a crate engine $4,000–$12,000 or more for performance applications. Doing both engine and transmission together typically runs $4,000–$12,000+. The final number depends on the unit you choose, your vehicle, and how labor-intensive the install is — we'll give you a clear estimate up front.

Yes, but California has specific rules. The replacement engine must be the same model year or newer than your vehicle, must keep all its original emissions equipment, and must stay within the same weight class. There's an important distinction: a swapped engine (different from the original) requires a BAR Referee inspection and DMV notification, while a straight engine replacement with the same configuration does not. We work within these rules so your vehicle stays street-legal and registrable.

It depends on what was done. A swapped engine, one that differs from what the vehicle originally had, must pass an initial inspection at a BAR Referee station and get a Referee label before normal smog checks resume. A like-for-like engine replacement does not require the Referee.

Common signs include slipping out of gear, hard or delayed shifts, grinding or clunking noises, a burning smell, red fluid leaking underneath, and a check-engine light. Catching these early matters — a small issue caught now can sometimes be repaired, while ignoring it often turns a minor fix into a full replacement. If you notice these, it's worth getting it diagnosed promptly.

Often, yes. Especially on a vehicle you otherwise like and trust. If the cost of replacement is less than the value of the car, or less than what you'd spend replacing the whole vehicle, a swap makes financial sense. When the repair cost approaches the car's value, it's a closer call. We'll give you our honest read so you can decide with the real numbers in front of you.

A rebuild reuses your original unit with worn parts replaced; a replacement installs a different used, reman, or new unit. Rebuilds can be cheaper on common automatics, but a remanufactured unit is rebuilt to factory spec and dyno-tested, which can be more reliable. The right choice depends on your vehicle, your budget, and how long you plan to keep the car.

In many cases, replacing the engine is far cheaper than buying a comparable replacement vehicle, especially when the rest of your car is in good shape. A used or rebuilt engine at $1,500–$4,500 often costs a fraction of a newer vehicle. We'll help you weigh the replacement cost against your car's overall condition and value.

Usually not. Standard auto insurance covers damage from accidents and covered events, not mechanical wear or failure. So a worn-out transmission generally isn't covered. The exception is an extended warranty or mechanical breakdown coverage, which may cover part or all of it. If your failure resulted from a collision, that's a different situation.

It depends on the job and parts availability. A straightforward engine or transmission replacement might take a few days; a more complex swap, or one waiting on a sourced unit, can take longer. We order parts ahead, track the job internally, and give you a realistic timeline before we start, then hold to it.
