This adapter kit allows you to attach a Jeep 4.0L i6 (1992-2006) Wrangler TJ, YJ, XJ transmission (AW4, AX15) to a BMW M57 turbo diesel engine (North American Models, 2.5L and 3.0L).
We supply you with everything needed to bolt your transmission to a BMW M57 diesel engine.
Automatic and manual transmissions work with our kits, unless otherwise stated. Please specify above what transmission type you plan to use.
PRODUCT FEATURES
Our kit has numerous features that set us apart from the competition.
PREMIUM BILLET ALLUMINUM ADAPTER PLATES. We do not skimp on quality, and only use high quality 6061 Aluminum billets. Our tempered 6061 is far superior to the cheap cast non-tempered aluminum adapter plates typically seen with cheaper adapter kits. Our billets undergo a tempering process of heat treating and artificial aging to achieve the perfect strength and toughness for our application.
EXTRA FIRE WALL CLEARANCE. Our 2.3 inch thick adapter moves the M57 engine forward 2.3 inches from the transmission bellhousing. The transmission remains in the original position, keeping the shifter in the factory position for most vehicle conversions.
HIGH PERFORMANCE CRANK ADAPTER. Our nitride case hardened alloy steel crank adapters are designed for high performance applications. Rated at 800 ft-lbs of torque, we set the bar high and make sure our parts are not the limiting factor in your build. Nitriding is a low temp, low distortion heat treating process that significantly improves fatigue strength of the metal. Crank adapters undergo significant stress cycles, making them a critical failure point. This is not where you want to cut corners on quality materials or design. Shockingly, our competitor's kits only offer aluminum or untreated steel crank adapters. Is it cheap and dirty, does it make the wheels turn at the end of the day, sure! Are they engineered to be the best? Not a chance!
2.0kW HIGH TORQUE STARTER MOTORS. The Toyota 4.7 V8 Denso style starter motor is now our go to starter motor for all our Diesel Swap kits. It has an OEM proven track record, compact design, and best of all it is readily available and very affordable to replace! These starter motors can be clocked to two or more positions to avoid any fitment issues in your engine bay.
MULTIPLE ENGINE CLOCKING POSITIONS. Our 2 plate system allows the engine to be clocked at 10°, and 20° (OEM Angle) for fine tuning engine clearances. The transmission stays stationary while the engine rotates towards the passenger frame rail.
This kit was specifically designed to replace the Jeep 4.0L i6 (1992-2006) engine. This kit makes the back of the BMW M57/N57 engine look like the engine block it is replacing. This means you can bolt any Jeep 4.0L (1992-2006) transmission to this adapter kit.
***1987-1991 4.0L engines will need a different pilot bushing, please order the 4.0L pre-1992 adapter kit if this applies to you.***

(2) Adapter plates, billet aluminum, 2 engine clocking positions.
(1) Crank adapter; nitride case hardened alloy steel for high performance applications (800ft-lbs torque). Pilot bearing pre-installed for manual kit.
(1) Starter motor:
-Toyota V8 high torque starter motor, Denso style compact 2.0kW
Installation hardware for bellhousing, crank adapter, and starter are included. No flywheel/flexplate bolts are included. You need to use OEM equivalent flywheel bolts.
OEM flywheel bolt size: 6 bolts, 1/2 - 20 x 0.875"
OEM flexplate bolt size: 6 bolts, 1/2 - 20 x 0.500"
HOW DOES THE ADAPTER WORK?
Our adapters make the back of the M57 engine physically resemble the back of the original engine it is replacing. No drilling or welding required, no custom flywheels, or shorted input shafts. Any transmission that originally bolted to your engine will work with this adapter kit.
WHY ARE THERE TWO ADAPTER PLATES?
Our two plate system allows you to clock/rotate the engine while keeping the transmission in the stock orientation. There are two different clocking positions: 10 degrees, or 20 degrees.
DO I NEED A FLYWHEEL OR FLEXPLATE?
Our TDI kits utilize the original flywheel or flexplate from the original engine being replaced. You will not need the BMW M57 flywheel, clutch, torque converter, or starter motor.
HOW ACCURATE IS THE TRANSMISSION ALIGNMENT?
We use our Aerospace Grade CMM to pull all the dimensions off the original engine. It allows us to precisely reverse engineer the bolt pattern down to 0.0001". Incorrect alignment will cause premature failure of the pilot and input shaft bearings, excessive clutch plate wear, and internal gear binding.
HOW EASY IS A DIESEL CONVERSION?
-It depends on which vehicle you want to convert and how much mechanical experience you have.
-If you approach the conversion in stages you can get the vehicle driving in less than 5 days.
-Stage 1, do your research first, and lay out all your required tasks.
-Stage 2, focus on getting the engine in and driving with very minimal changes to engine and wiring harness.
-Stage 3, after you confirm the engine runs and drives, start your performance upgrades, custom wiring harness, gauges, engine rebuilds, etc.. This method reduces the number of variables you introduce to the project, and significantly increases your conversion success. Too many people make too many changes right from the start or try to make it perfect the first time round. Take it slow, minimize the number of changes all at once, and you will have a successful conversion!
-You will need regular mechanic tools, engine hoist, welding machine, basic fabrication knowledge, some electrical knowledge, and beverages.
DOES TDCONVERSIONS DO CONVERSIONS ON CUSTOMER VEHICLES?
-Not currently. We sell the conversion kits to get your engine into the vehicle and bolted to the transmission.
DO AUTOMATIC TRANSMISSIONS WORK FOR CONVERSIONS?
-Yes an automatic transmission will work with our adapter kits.
-You will need a standalone TCM controller for your specific transmission. These controllers are highly tunable and have manual shift modes.
-Be aware of your torque converters stall speed and full lock RPM. You may need to purchase a new converter that better suits the M57.
