Jeep Grand Cherokee ECMs, PCMs, and TCMs for Sale

Powertrain Control Module for the Jeep Grand Cherokee?

The Jeep Grand Cherokee is something you can drive to work one day, and take off-roading the next. Its powertrain needs to handle the stop-and-go monotony of rush-hour plus the chaos of a full-on mud bog.

And you should expect nothing less from your ECM.

We carry engine and transmission computers for most North American Grand Cherokee vehicles, 1996-2009. We have plug-and-play ECMs in stock for all different engines, from the 4.0L I6 to the 6.1L HEMI.

1st Generation Grand Cherokee?

The 1st generation Grand Cherokee was available with either a 4.0L I6 engine or a 5.2L V8 engine. Each engine requires a different computer: An ECM for 1998 4.0L I6 will not work with a 5.2L V8 engine of the same year. We carry computers for vehicle model years 1996-1998 with an average price of $260.

Before you place your order, please call us to confirm you have the right computer for your vehicle. Have your VIN or the OEM part number for your ECM handy-we'll need it for reference.

2nd Generation Grand Cherokee?

The 2nd generation Grand Cherokee was produced from 1999-2004. It was available in North America with a 4.0L Inline 6 engine and a 4.7L V8 engine. Both powertrains require separate computers for controlling the engine and transmission.

Both versions of the Grand Cherokee use the same computers for the same vehicle model year: An ECM for a 2003 4.0L I6 will also work with a 2003 4.7L V8. The same is true for transmission controllers (TCM) as well.

We have ECMs in stock for all vehicle model years, 1999-2004, with an average price of $360. We also carry TCMs for model years 1999-2003 with an average price of $260.

3rd Generation Grand Cherokee

The 3rd generation Grand Cherokee was produced from 2005 to 2010 and came available with four different powertrains: 3.7L V6, 4.7L V8, 5.7L V8 HEMI and 6.1L V8 HEMI SRT8.

3.7L V6 & 4.7L V8 Engines?

Grand Cherokees with 3.7L and 4.7L engines of the same year use the same engine computer: A 2007 3.7L Grand Cherokee ECM will also work with a 2007 4.7L Grand Cherokee. We carry ECMs for model years 2005-2009.

Our ECMs start at $240, up to $360.

5.7L V8 HEMI & 6.1L V8 HEMI SRT8

Grand Cherokees with 5.7L and 6.1L V8 engines of the same year use the same engine computer: A 2007 5.7L Grand Cherokee ECM will also work with a 2007 6.1L Grand Cherokee. We carry ECMs for model years 2005-2009.

Our 5.7L plug-and-play ECMs range from $640 up to $700.
