Description:

The Nifty Shifter JR V1 is a Passthrough Manual Shift Controller designed for the Jeep AW-4 Automatic Transmission. This Plug-&-Play controller attaches to the Transmission Computer to give you Manual Control at the flip of a switch and shift it any way you like!

In Auto Mode, your transmission will shift normally, allowing for a permanent and painless install.

In Manual Mode, the user takes full manual control with a couple of shifter types! The Nifty Shifter can use custom switches/joysticks or the Factory PRND31 Shifter to select and hold each gear for a clean and functional solution!

The provided ribbon cable allows you to wire up any kind of switch, button, joystick, or contact you wish for your custom controlling needs. Selection Switches on the controller let you easily configure the shifter settings on the go.

Available Inputs:

– Gears 1, 2, 3, 4

– Torque Converter Lock Up

– Auto/Manual mode

– Overdrive Mode (Factory Shifter mode only, allows 2,3,4 instead of 1,2,3)

– Manual Bypass Mode (Gearbox mode only, allows gear switch to also activate manual mode)

Selection Switch configurations:

Shifter Type Switch:

Factory Shifter mode

– Uses the vehicles shifter to manually select gears (Requires working NSS)

– Minimal install required, Engine Braking available in every gear

Gearbox mode

– Uses separate inputs like a 4-speed manual transmission

– Custom setup required but gives you more control

– If optional Jumpers are set, can accept a RADesigns Rail Shifter instead

Torque Converter Mode:

Selects how the TC is controlled

– Off is Normal mode (Auto: TCU, Manual: Switch)

– On is Factory mode (TCU always controls TC, can still activate with manual tc switch)

Optional Screen:

– LED Single-Digit display shows Current Gear and TC Lock

– Optional ACC Switch can be wired to any ribbon cable input for a Ready-To-Run setup

– Designed as a self-sufficient module, so technically this could be wired directly to the TCU without a Nifty Shifter

In the Box:

– Nifty Shifter JR shift controller

– Ribbon Cable for switch wiring

– Optional Gear Display

– Instruction Manual

Notes about the AW-4 Transmission:

The Aisin Warner AW-4 4-Speed Auto Trans has 4 available gears to pick from with 4th being overdrive, as well as an electronically controlled Torque Converter Lock-up. Available Gears and Engine Braking are MECHANICALLY LIMITED and depends on the Factory Shifter Position.

Engine Braking is useful for controlled descent down hills and slowing down without using the brakes. Without Engine Braking, the engine will free spin like a bicycle if the transmission is spinning faster then it. This means you could shift into 1st on the highway and your engine would just sit at an idle, while revving it would never spin fast enough to push the transmission, just as shifting a mountain bike to 1st would require pedaling ridiculously fast to keep pushing the bike. If the factory shifter was put into D1-2 on the highway though, Engine Braking would be active and you’d be having a really bad day.

The Throttle Valve Cable connected to the Throttle Body controls shift pressure so the harder the pedal is pushed, the harder the transmission is shifted. Making sure this is properly adjusted will provide a better shifting experience.
