The Autosports Engineering LS to Jaguar 8HP conversion kit adapts a Jaguar or Land Rover ZF 8HP45 or 8HP70 eight-speed automatic transmission to any Gen 3, Gen 4, or Gen 5 GM LS or LT engine. The kit includes a billet torque converter flex plate that fully replaces the weak stamped-steel OEM LS/LT flex plate and a billet engine-to-transmission adapter plate with an integrated dust shield.
The flex plate in this kit is a full replacement for the factory LS/LT unit — not a converter spacer that leaves the stock stamped plate in service. On a high-torque swap the OEM plate is the weak link long before the transmission is. CNC machined from heat-treated billet 6061-T6 aluminum and engraved.
The Jaguar 8HP uses a single-diameter torque converter pilot, so no pilot adapter is required with this kit.
The Jaguar 8HP45 and Jaguar 8HP70 share the same four-bolt torque converter, which is unique to the Jaguar application. Because the converter bolt pattern is common across both, one kit covers both transmissions. This is not the same as the older Dodge 8HP45, which uses a different converter and is not supported.
The engine side is a bolt-on and the stock LS starter works unmodified. No converter bolt access window needs to be trimmed into the Jaguar bellhousing.
Running a used transmission? Fluid and filter should be changed before it goes in the car. Budget for a ZF service kit alongside this adapter.
What GM engines does this LS to Jaguar 8HP conversion kit fit?
All Gen 3 LS 4.8L, 5.3L and 6.0L except early long-crank 5.3L and 6.0L engines; all Gen 4 LS 4.8L, 5.3L, 6.0L, 6.2L and 7.0L including 8-bolt and 9-bolt crank variants by special order; all Gen 5 LT engines; and Gen 5 LV1 and LV3 4.3L direct injected V6 engines.
Which ZF 8HP transmissions does this adapter kit work with?
Jaguar F-Type 3.0L V6 2013 to 2020 and 5.0L V8 2014 to 2020 on the 8HP70, Jaguar X250 XF and XJ 2015 to 2019 on the 8HP45, Jaguar XF 3.0L V6 2013 to 2020 and 5.0L V8 2014 to 2020, Jaguar XJ 3.0L V6 2013 to 2020, and Land Rover Range Rover Sport 5.0L V8 2014 to 2017 and 3.0L V6 2014 to 2019 on the 8HP70.
Does this kit fit both the Jaguar 8HP45 and the 8HP70?
Yes. The Jaguar 8HP45 and Jaguar 8HP70 share the same four-bolt torque converter, which is unique to the Jaguar application, so one kit covers both.
Will this work with a Dodge or Ram 8HP transmission?
No. The older Dodge 8HP45 uses a different torque converter and is not supported. For Mopar and Ram 8HP70, 8HP75, 8HP90 and 8HP95 transmissions, use the LS LT Dodge Mopar 8HP conversion kit instead.
Do I need to modify my starter or the transmission bellhousing?
The engine side is a bolt-on and the stock LS starter works unmodified. No converter bolt access window needs to be trimmed into the Jaguar bellhousing.
Do I need a pilot adapter for the torque converter?
No. The Jaguar 8HP uses a single-diameter torque converter pilot, so no pilot adapter is required.
Do I need to reuse my stock flex plate?
No. The billet flex plate in this kit replaces the factory LS/LT unit entirely.
What flywheel bolts does this use?
Standard-length OEM GM or ARP manual transmission flywheel bolts, 6 or 8 depending on your crank. Bolts are not included — use ARP for anything making real power, torqued to ARP spec with thread locker and ARP lube under the head.
Will this work with an aftermarket oil pan?
Yes. The adapter plate uses all seven fasteners with a factory GM cast oil pan for maximum rigidity, or five fasteners with a fabricated steel pan. Both configurations are supported by the included hardware.
Does this include the transmission, torque converter, or controller?
No. This is the mechanical adapter package only — adapter plate, flex plate, and hardware. You will source the 8HP, converter, controller, driveshaft adapter, and mount separately. The 8HP is electronically controlled and will not shift without a standalone transmission controller.
