In 1994, the Grand Cherokee used a four-speed automatic transmission. The engine choice determined the exact unit: 4.0-liter inline-six models used the 42RE automatic, while 5.2-liter V8 models used the 46RE automatic. A factory manual option was not offered that year.
Understanding these pairings helps owners and buyers identify replacement parts and confirm the original equipment. The rest of this report outlines the two main transmissions, how to verify which one your vehicle carries, and practical maintenance notes.
Transmission options by engine
4.0-liter inline-six with a 42RE automatic
The 4.0 L engine in the 1994 Grand Cherokee typically paired with Chrysler's 42RE four-speed automatic transmission, a common setup for this powertrain in the era. The 42RE uses electronic controls and offers overdrive for highway efficiency.
5.2-liter V8 with a 46RE automatic
Models equipped with the 5.2 L V8 generally used the 46RE four-speed automatic, a heavier-duty variant designed to handle the V8's torque. This transmission is part of Chrysler's RE family and also features overdrive and electronic control.
Both configurations deliver four forward gears and similar overall drive characteristics, with the difference mainly in torque handling and gear ratio tuning.
How to verify the transmission on your vehicle
To confirm which transmission your specific 1994 Grand Cherokee has, use these identification steps.
- Inspect the transmission itself for a model code. Look for markings such as 42RE or 46RE stamped on the case or on a tag near the bell housing or pan.
- Check the Vehicle Identification Number (VIN) and build sheet to see the original equipment, which will indicate the engine-transmission pairing.
- Consult the owner’s manual, factory brochure, or a Jeep service bulletin for the 1994 model year for official wiring and trans specifications.
- If you can't locate a code, have a qualified shop perform a quick transmission identification test or read the transmission control module to confirm the software/firmware linked to the control unit.
Correctly identifying the transmission helps with parts compatibility, service intervals, and potential upgrades or repairs.
Summary
The 1994 Jeep Grand Cherokee used a four-speed automatic transmission across its lineup, with the 4.0-liter inline-six paired to a 42RE and the 5.2-liter V8 paired to a 46RE. A factory manual option was not offered in that year; verifying the exact unit on a given vehicle is best done via the transmission code, VIN build sheet, or a trusted mechanic.
