Have 1996 jeep grand cherokee larado with chrysler 318 engine and auto transmission, all the time four wheel drive with I believe to be a NP249 transfer case...have not used the low gear range for years....just never needed it....now went to use it and could hardly get shifter to move....finally got it to move to low position, but when put from neutral to drive, hear hear grinding in transfer case like it is not going all the way into gear...one time it did go into gear and it drove in low range and then I stopped and put in park and started again it would not go into gear again....is this a linkage adjustment problem or a transfer case problem....also the 4 low light on center console only came on the time it fully engaged and drove in low gear. Thanks for your help...my email is [email protected]

why not just read it all your self.

the dealer has a Database tells you what shipped with car.
then look here.
97 grand, ZJ
usa car?
what engine, must be guess that tool?
4.0L
or 5.2L
the trans matches the engine and matching PCM.
they cant be mixed up
42 and 44RE
if in Europe and a diesel now's be the time to fess up, no?
it has 3 shift solenoids in the transmission the TCM/PCM does all shifting. auto.


here is the jeep aparts page in the 42

jeep has one of the best, online parts support of any car made
check it out.
for sure full drawing to find part and match up, numbers.

The best support site I have found for Dodge is here, Allpar Dodge Chrysler Plymouth Jeep and related cars minivans and trucks Look in the tech sections and you may find the answer or you can type in a question. Contrary to what one user posted, I have no affiliation with this website beyond having used it myself. Allpar Dodge Chrysler Plymouth Jeep and related cars minivans and trucks

Cars are like that. I think they like driving people crazy. I\'ve been driven crazy by my Sentra for three months now.
Has the fuel pressure been checked? I wonder if your fuel pressure regulator has failed (the diaphragm inside will rupture and suck extra gas in through the vacuum hose attached to the regulator-could be the cause of backfiring). Something to check, anyway.

Not sure but mine was about the same speed and it was a bad u joint in the front

Try neutral. or in drive, but just crawling. Give light pressure to the stick and sort of let it just fall into 4x4

it sounds like your automatic transmission quit his job. How much miles are on the clock? If more than 150.000 and you pulled trailers, climb mountains etc. this will be the first choice. Let the engine idle, push the brakes and check if the car will go in any gear. If this will happen only in reverse gear, your auto trans need to be replaces. You can use a rebuilt auto trans.

Sounds like the splines on your transfer case gear are ground down

Hopefully this will answer your question.

The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor. The structure was stiffened by PorscheEngineering for sharper steering and lighter weight. The spare tire wasrelocated from the side of the cargo compartment to under the floor togreat relief of owners. The two heavy pushrod V8 engines were replaced by chrysler's first clean sheet V8 since the 60's (SOHC aluminium heads, plastic intake), Chrysler's then-new PowerTech. Although this engine produced less torquethan both previous V8s, it was lighter and got much better fuel economyand provided similar on road performance figures (the 23 gallon fueltank was replaced with one of a 20.5 gallon capacity). The Inline 6engine was also updated in 1999. 10 horsepower (7.5 kW) was added byredesigning the intake manifold. The manual transmission was dropped with this model.
While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, thiswas the first Jeep following the 1987 Chrysler buyout to receive awider bolt pattern — 5 x 5. The 5 x 5 bolt pattern (also 5 x 127 mm),although common to GM rear wheel drive vehicles and light dutytrucks/vans, has spread beyond its use with GM (and Ford with their 1973 to 1978 LTDs and Lincolns). Chrysler first used the 5 x 5 pattern on full-size half-ton Dodge Ram pickups and Dodge Ramcharger SUVs in 1986.
A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive II.With three viscous clutches, it was one of only a few four wheel drivesystems at the time with triple locking differentals, joining thecontemporary Mercedes Gelandewagen, Mercedes Unimog and Magna SteyrPinzgauer, and the only one of the four with fully automatic operation,although the axle differentials could not be manually locked like inthe other three vehicles.
The 45RFE and 545RFE automatic transmission in the WJ was notable. It included three planetary gearsets rather than the two normally used in a four-speed automatic. Thisgave it six theoretical speeds, and it would have been the firstsix-speed transmission ever produced in volume, but it was programmedto only use five of these ratios. Four were used for upshifts, with adifferent second gear for downshifts. Although five of the six ratioswere used, Chrysler decided to call it a "4-speed automatic". In 2001,the programming was changed to make use of all six ratios. Rather thanhave six forward gears, the transmission was programmed to act as afive-speed with the alternate second gear for downshifts. The RPM at70 miles per hour (110 km/h) on a 545RFE is 2000 rpm, 200 rpm less thanthe 45RFE programming. 1999 and 2000 model year WJ owners can havetheir 45RFE transmission's programming flashed to enable the extra gearas both transmissions are physically the same. The 42RE 4-speedautomatic remained the transmission for the Inline 6 engine. It was notchanged from the previous model Grand Cherokee's.

Any all wheel drive will give less fuel miles.(compared to ones you engage as needed) The Chrysler v8 is a time proven engine, pretty much a copycat of a chevy with some changes to make it their own. Overall, I haven't heard any really bad stuff about them. If you look at the problems on this site, there seem to be fewer jeep probs than all other vehicles. (even though some problems are really weird!!!)
What you really need to see is the vehicles history to make sure it's been maintained and has not been back to a shop for the same thing over and over.
Good luck!

Is it all wheel drive? I believe it's telling you it's in four wheel drive or the sen is going bad in the all wheel drive
