Jeep Cherokee XJ 1998 I have use this car for the last 10 years no issues with the transmission and have check the fluid level and it's in good condition and at good level. While driving in D up to whatever speed above 20 mph and lift my foot from the gas the revolutions goes down to 700 like if it was in neutral, as soon as I step in the gas it will smoothly accelerate like nothing happened. Thoughts?

As I said in your last question, there are very few reasons you need to go near it. A good auto electrician with a professional grade scan tool computer can diagnose the ECM for faults in about 20 to 30 minutes. It is not a job for 'let's try changing this'. If it is bad, a new one needs a tech to install as it has to be programmed with the VIN Number and mileage and set up.

Your dealership is spinning you a year to get you to pay for a new transmission. Tell you husband to get back underneath and look for pulled or damaged wires from the bumper job.

Or call a transmission specialist. This is an electrical fault.

chapter 14, fuel
page 20 is tank, in fact its all there, and 100% FREE,
no engine stated, and fuel system is not the same.
page 17 cover pump, in tank.

P1784 low reverse pressure switch sense circuit.
Start by checking fluid level and condition. then check electrical connections. if all ok, probably solenoid in the valve body assembly.

P1767 Transmission Relay Always On. Transmission Range Sensor Circuit Malfunction (PRNDL Input)

Start with the simple and Check your fuses and transmission fluid level, if the level is good and the condition of the fluid is good. There may be an issue with your solenoid or your transmission pump. You can check your pump buy checking your transmission fluid level with the engine not running and take note where the level is. Then start the engine and check the fluid level again, if the level has gone down. The your pump is good, if it does not go down. Then your pump has gone bad and your going to have to rebuilt the transmission or replace the pump.

You better of replacing the whole transmission of the pump has gone bad, since the low transmission fluid pressure would have worn out most for your clutches throughout the transmission.

Thank you for using Fixya and hope is just a simple Solenoid that has gone bad or a wire harness that has shorted out.

Not a lot of info to go on,but check the fluid levels if things are a bit harsh.It's usually the problem.Look for leaks.Hope this helps

You might have some sticking calipers. Also check the transmission fuild level and transfer case fluid level.

here can find two documents:
- Jeep XJ Cooling-System Section 7
- Jeep XJ Cooling-System Section 7a

Also, the other sections about Jeep XJ Cherokee Service Manual

Hope thats help (remember rated this). Good luck.

To change the transmission fluid you drop the transmission pan should be about 16 bolts. Once that is off you will see the filter. Buy the kit from a local auto parts store and look to see what the filter looks like. Check your transmission fluid once you drain to see metallic look in it if so i would suggest a transmission flush.

Good luck!!!

If the Jeep sat for 3 years, u may have brake issues, which is why it won't move when u put it in gear. The brakes may be dragging, or partially seized. U can jack up one wheel at a time, block all other wheels so it won't fall and kill u, w/ trans in neutral try to spin the wheels by hand. If u can't or there is a lot of effort needed, check out the brakes. Calipers and brake cylinders may need to be replaced, and u should also flush out the brake fluid, or your new calipers and brake cylinders will eventually corrode and seize again.
Where is the knocking sound coming from. the engine?
