I've had some electrical problems, specifically the electronic gear selector. I hope this isn't a blown transmission. Has anyone else experienced this with their Jeep?
IMHO, Jeep/Chrysler hasn't had a great rep for the transmissions within the past 20 years. In most instances, transmissions should last the entire lifetime of the vehicle when cared for properly. Checking fluid levels regularly, as well as following manufacturer service intervals make the difference. Keep in mind that transmission fluid should be changed just like your oil, but on a very different schedule.The Grand Cherokee being a model plagued with transmission problems especially if you have the four-wheel drive "Quadratrac" transfer-case package. I am not sure sure if this is a "maintenance free" (I hate that term) or "sealed for life transmission" and case. If it is, I feel very sorry for you because like many others, you have been mislead. Transmission fluid does in fact have a service life and the fluid certainly takes a beating. Not only does it lubricate your transmission as oil does for an engine, it acts as a coolant, and it is also a hydraulic fluid to assist automatic shifting in the case of automatic transmissions. Transmission fluid should be changed because old fluid loses viscosity and can become "dirty" due to natural surface oxidation of internal parts. Unfortunately, usually by the time a transmission starts "acting up" or starts making noise the damage is already done. If you have an automatic, the whole transmission will have to be redone or replaced. If it is a manual trans its possible certain components can be replaced. I have had a girlfriend and co-worker who both had these Jeeps with automatic and wound up ditching them because of tranny or xfer-case issues. One jeep started having trans problems at 70,000 miles. :-(

First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.

No, not with out a lot of work. Electronics are most likely different on the 2 also.
SOURCE: transmission will not shift, drives only in low
sound like over filled. drain out fluid change fluid and filter put the right amount in it.
SOURCE: noisy shifting
I'm wondering if what you are hearing is the driveshaft universal joints. If they are worn they will 'clunk' every time you put the vehicle in gear. Block all wheels to check, put vehicle in neutral, NOT running, crawl under and move the driveshaft back and forth while watching the front then rear u-joint. It should be obvious if there is 'slop' or 'play' in them, which would indicate they need to be replaced.
Testimonial: "thanks for the response. i will follow your advice "
