My grang cherokee2002 us spec, while driving trnz changes fine but when cick down or full excelrate and RPM reaches 4.5 or 5 engine is loosing power and getting noisy and RPM not going more, while gear on...


You are hitting the rev limiter top range, which cuts off your ignition.

I have a 2001 Grand Cherokee and the problem drives me crazy, but it is the way the car is designed- as soon as you hit the rev limit, it shuts down ignition and your jeep will "buck" - a real pain when you are trying to accelerate into traffic!

You have the 4.0L straight six engine, yes?

If so, please take my advice and learn to live with the minor annoyance of the rev limiter- that engine is IMHO the best Chrysler ever made (nearly "bulletproof"!) and it was so reliable you cannot even get it in a jeep now! For decades, that engine was used in welders, tractors, generators...and yes, jeeps... and it is a favorite among mechanics for its durability!

I have a 99 jeep grand cherokee ltd, 4.0 L, 6cyl, auto, 4wd, 87000 miles. My problem is that on the first start of the day and when the engine is cold, the transmission wont shift from 2nd to 3rd until...


I'd begin by having the trans fluid changed and making sure there isn't an excessive amount of debris in the pan (there is always some but should not be obviously a lot) You may have a slight varnish buildup inside that becomes less sticky as the internal temp rises.

02 jeep grand cher. stays in 1st gear till 4500 rpm's before changing. I replaced the transmission speed sensor and it was fine for about 3 weeks then started it again. Would a shift solenoid sensor help...


Which trans do you have??? The 4.7 has the 45RFE and the 4.0 has the 42RE. If you have the 42RE, try replacing the connector on the output speed sensor. I have seen intermittent problems with the connectors as they get older leading to falling into low gear and not shifting up

2002 jeep grand cherokee auto trasn is not changing gears


Personally, I'd drop the trans pan and give a look...but, best advice I can give you is to get to a REPUTABLE trans shop ASAP and not drive it unless its an emergency 'till then (more you drive, more damage you will do) The way a transmission is assembled, makes just about anything impossible without teardown.
And yes...only one filter in there.
