    similar problem, except Jeep periodically loses power, RMP drops to zero for a few seconds, the power returns and Jeep continues to run. It is scary, especially on the freeway! Is this the same problem?

Jack up your Cherokee and look underneath for a wiring harness that leads to a sensor that is between the engine and trans. This is your crank sensor. Pull it out and check the condition. Mainly look at the wiring harness to the sensor. These Jeeps have a habit of breaking and your Jeep with just turn off going down the road. These wiring harnesses are available at the dealer and are fairly inexpensive.

I have a 95 jeep grand Cherokee 4.0 6 cylinder and I need a new tranny but I have one from a 99 grand Cherokee. Will the 99 tranny work in the 95?

A salvage yard would have the interchange books to tell you for sure. The newer trans may have more electronics.

In my 2009 jeep grand Cherokee there is no 4 Ed shifter. Is pressing the "ESP" button engaging the 4wheel drive?

On the Jeep models, ESP means electronic stability program which is the same as traction control.
There are 3 different versions of four wheel drive on Jeep Grand Cherokees with the base version being all wheel drive.
Your owners manual should tell you which version you have and how it operates.

2004 Jeep Grand Cherokee. Keeps stalling, engine

P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

I have a 1999 jeep grand Cherokee Laredo that just shuts off while driving. I took it to a mechanic and he replaced the PCM and I also changed out the Crankshaft Position Sensor. Now the Mechanic is...

Sounds like you have a "parts replacer" not a technician. What kind of testing was done? Or. is he just guessing and charging you for that? What's wrong with the harness that was not wrong since "99? Unless it was crushed or cut or burned, the only problem with a harness generally is that where each wire enters the pin at it's end, sometimes that connection will deteriorate, and the pin will show no voltage. It may be time consuming to find the pin(s) but knowing the symptoms eliminate a lot of them.
When found, usually the connection can easily be restored or pin can be changed. I don't enjoy that work but have done it many times, always with good results.

I had a problem with my Jeep doing the same thing. It turned out to be the Crank shaft senor. It would just turn off even on the highway at 60mph.
If you can change it yourself you will save a lot of money.
