1997 grand Cherokee limited jeep cuts off without warning why?
Check the PCM/Power Control Module/Computer. I had a 98 do the same thing to me. The PCM will be hot to the touch when the problem occurs.
The PCM is located on the passenger side firewall in the motor compartment, behind your radiator overflow bottle.
The most compatible and completely interchangeable transmission that can be used with a 1999 Jeep Grand Cherokee Limited is the 45RFE transmission. This is from a 2000 Jeep Grand Cherokee. Only this model year is compatible with the 1999 model year as the vehicles shared 127 of the exact same parts.
