Transmission Adapter Plate & Swap Kits
When building a custom vehicle powertrain, one option is to swap out the transmission for a different type or model. To connect transmissions to engines that they were not designed for, transmission adapter plates are needed. Off-the-shelf engine to transmission adapters help make the conversion much easier than having to design and make custom transmission adapter plates. JEGS offers transmission adapter plates and swap kits from top brands like Quick Time Bellhousing, Trans Dapt, TCI, Lakewood, JEGS, and others. Automatic and manual transmission swap kits provide the plate and components you need to properly mate your engine to the transmission of choice. Browse our full line of transmission adapter plate and swap kits to help complete your custom engine and transmission setup.

For restomods or other custom vehicle projects, matching up a transmission to an engine for which it wasn't designed can be a real headache. That's where an engine to transmission adapter kit can come to your rescue. Sure, you can fabricate a transmission plate that would probably work, but a Chevy engine to transmission adapter (for instance) has everything you need for this conversion, making the swap a lot easier and headache-free.
There's more to this job than just the transmission plate, of course. You may need parts like the motor plate, a crankshaft spacer to match up to the torque converter (on pre-1997 Chevy drivetrains), shim kits and maybe even a crossmember. The adapter plate is machined from aluminum or steel and is designed to bolt to the back of the engine block, using the bolt pattern the engine was manufactured with. The other side of the adapter plate will have bolt holes laid out to match the bolt pattern of the transmission to ensure compatibility.
In some instances, using an adapter plate might mean removing the transmission's bellhousing and bolting up the adapter in its place. When properly installed, the adapter plate not only ensures that the engine and transmission are securely matched up, but it heads off any headaches with misalignment, balance issues and leaks.
If you're in need of an adapter plate or swap kit to facilitate your project, we've got what you need right here, from top brands like Lakewood, ICT, Hurst, Gearstar, JEGS and Quick Time. A high quality, precision manufactured adapter plate or swap kit can ensure a reliable connection between engine and transmission and can make your swap or installation go a lot smoother.

How Is Engine Connected to Transmission?
The connection between an engine and a transmission in an automotive setup is crucial for transferring power generated by the engine to the wheels. This connection is facilitated by a component known as a transmission adapter plate. Here's how it works:
- 1. Adapter Plate: A transmission adapter plate is a precisely machined piece of material, often made from aluminum or steel. It serves as an interface between the engine and the transmission.
- 2. Bolt-On Installation: The adapter plate is bolted onto the back of the engine block, where it matches the engine's bolt pattern.
- 3. Transmission Compatibility: The other side of the adapter plate is designed to match the bolt pattern of the transmission.
- 4. Secure Connection: By connecting the engine and transmission using the adapter plate, a secure and precise connection is established. This allows for the transfer of power from the engine to the transmission without misalignment or play.
It's essential to choose the right transmission adapter plate for your specific engine and transmission combination to ensure a proper fit and optimal performance.
What Is a Transmission Adapter?
A transmission adapter is a crucial component in engine and transmission swaps or conversions. It's designed to address compatibility issues that may arise when installing a different engine or transmission into a vehicle. Here are its key functions:
- 1. Compatibility: Transmission adapters are engineered to bridge the gap between an engine and a transmission with different bolt patterns or mounting configurations.
- 2. Precision Engineering: These adapters are precision-machined to ensure a perfect fit, maintaining the alignment and balance between the engine and transmission.
- 3. Flexibility: Transmission adapters come in various designs and thicknesses to accommodate different engine and transmission combinations.
- 4. Installation: Installing a transmission adapter often involves removing the existing bell housing and bolting the adapter in its place.
Overall, a transmission adapter plays a crucial role in simplifying engine and transmission swaps, making it possible to install non-OEM powertrain components into a vehicle.
How Much Does an Engine to Transmission Adapter Kit Cost?
The cost of an engine to transmission adapter kit can vary depending on several factors. These factors include the type of engine and transmission you're working with, the brand and quality of the kit, and any additional components or accessories included. On average, you can expect to pay anywhere from $100 to $500 or more for an adapter kit.
It's essential to choose a kit that matches your specific engine and transmission combination and provides the necessary hardware for a successful installation. Investing in a high-quality adapter kit ensures a reliable and precise connection between the engine and transmission.
