1995 Jeep wrangler with sick automatic transmission by lewz
Feb 20, 2008 (6:09 pm)

My 1995 4 cylinder jeep with a three speed automatic transmission (132,000 miles) has a problem with down shifting from the high gear. I have replaced the filter and added a conditioner for automatic transmissions and did get better up shifts but still have this nagging down shifting problem. As the jeep slows down it begins to shudder and occasionally stalls since it wants to stay in 3rd gear.
 
Does anyone know if this is caused by a solenoid valve sticking ? If so thats an easy fix for me. If not its time for a rebuild.
 
Problem is more prevelant during cold weather.

Hello all,
 
Here is the update for the 1992 Wrangler with the "whining" sound. As of today, the rear differential has been completely rebuilt and driven for more than 1,500 miles. The "whining" noise has gone away as far as I can tell. According to the mechanic who works on off-road vehicles, the previous shop (a general transmission shop) who had done a kit rebuild on the rear differential (wrangler had ~185,000 on it at that time) did not do the job correctly which is why it only lasted 40,000 miles. I took it back to the off-road shop for a 1,000 mile check after the rebuild and the rear differential looked great.

2000 jeep wrangler driver by jphill33

hello,
i drive a 2000 jeep wrangler se sport 4.0L 4x4. i'm a student working on my BS degree in nursing. one day i took my jeep out to enjoy some mud. a week later i noticed that the jeep wasn't driving just right so i took it in to have the clutch looked at and i replaced it. however, the problem wasn't fixed. i'm a novice with mechanical issues so i asked a friend for advice. i took the jeep to a transmission shop and the problem was clear. i fluided the transmission with water/mud. so i had the transmission rebuilt for 1,200 dollars. a year and a half later which is the present, my second gear is grinding bad when i shift into it. i took the jeep back to the transmission shop and the shop owner informed me that the gear was bad. he said that jeep is aware of this common issue in the 2000 jeep wrangler and that it would be extremely expensive to fix the tranny. he said i could either put in a rebuilt 2nd gear that might not last a year, or completely replace the tranny and drive shaft. well i dont have a lot of money since im in school. so i decided to just shift from 1st to 3rd until i can afford to fix the problem. now 3rd gear is starting to drink just slightly ever once in a while. i'm concerned that this will only get worse. someone please help me. i love my jeep and i would hate to sell it, just because i cant spend the money to fix it. and it sounds like if i fix it i will continue to have issues later down the road.
thank you for listening,
josh

Can't get it in gear by jeepgirl25

I just picked up my 2008 Sahara - automatic - last week. Since then, several times after I start the engine and try to put it in drive or reverse, the shifter won't move. I can't get the button to push in to move it. After trying it a few times, it eventually goes, but I fear the day it doesn't. Anyone else have this problem? Ideas?

You either don't have your foot pressed hard enough on the brake pedal, or adjustment is needed to the brake/transmission interlink.
Try more right leg pressure first.

My 07 does the same thing. I'm not sure but I think it might have something to do with the hill holding feature. After you put your foot on the brake pedal it sometimes "takes a sec" to settle to the bottom of the brake travel. The shifter release is tied to a switch that must be fully pushed down. Give it a sec and then the shifter should go. Mine was a little worse after I had my recall fixed for the hill holder. Hope that helps.

No power to front with Quadra Track II by dmenchen
Mar 11, 2008 (2:02 pm)

I have a 99 Grand Cherokee that is not getting any power to the front axle. Additionally, the power that is going to the rear is only going to one wheel. If the jeep is in snow or ice it will just spin one of its rear wheels. This is totally opposite of what the drivetrain should do. Can you suggest a possible problem to look at? Would a lack of or wrong lubricant in the transfer case / viscous couplers do this? I had the oil changed and the differential fluids changed some time back. Thanks...

Ok lets start here.Your grand should be select trac. I hope Quadra trac is in the 70's , Don't get upset I'm just trying to get things straight and correct me if I'm wrong but if I'm not mistaken they only made select trac. for the 4.0l and the v8's were all time 4wd as far as I know. Now from what I know and I own a 99 grand 4.0l w/ 242 transfer case and had mine apart last year for a noise lets start here. I hope this is what you have if not let me know but in full time 4wd the front wheels should spin. If not lets go to the front axle and check from there back if you can jack up the whole car and block or have someone hold 1 front tire and watch your front driveshaft it should spin if not you have axle issues like spider gears or something, if that is the case you know it's in the axle. If that all works try putting it in 4wd full time and with 1 front wheel held or solid you should not be able to turn the other (tranny in park or gear if stick) if a wheel turns see what is turning underneath the car ie driveshaft. If drive shaft is turning sounds like a broken chain in transfer case. But I replaced mine and still had my noise only to find it to be a cv joint on my driveshaft and found that jeep had may types used on the grands that year start there and and you need more info let me know and we'll go from there. Thanks Jeremy Owner (jeeps n more 4x4)

Jeremy, Thanks for getting back to me.
My 99 Grand Cherokee is a 6 Cyl 4L and the console says it is Quadra Track II. It is full time 4WD with the left hand lever having 4H N 4L options. It snowed this weekend in Ohio which was my first chance in a couple of years to take the Jeep into low traction situation. I got stuck immediatly. It made no difference if I was in 4H or 4L. I am very puzzled as to why I didn't even get "posi - track" at the rear axle. A couple of years ago I had the guys at the oil change shop change the oil in the transfer case and (I think) the differentials (possibly not). It may not have worked since then... Thank you for your help.

That is something that can happen. Unless the differential is locked or you have a limited slip differential, this can happen. Normally the torque is distributed to the wheel with less traction or force against it. Seems backwards, but that is what it does offroad until the locker is engaged and equal torque is sent to both sides of the differential.
 
That is one reason our 2000 WJ Grand Cherokee had the Quadra Drive II, to help minimize that.
 
As far as your front axle goes, are you SURE you're getting it completely into 4hi or 4lo? Those levers can be a pain to get to where you need them to be and our 2000 was not easy to put in 4lo. Another dumb question, you sure your t-case has the front driveshaft installed? It can be removed with no ill effects in 2wd mode, but w/o it you won't be able to get power to the front in 4wd.
 
Improper fluids COULD cause the problem, but it would be a more long term thing. I use Redline fluids in my transmission, Mobil 1 in the transfer case, and a synthetic in my diffs (for my 97 Wrangler). Unless you need that specific additive for the Quadra Drive, you should be okay. I just don't know enough about those additives (I don't need em on mine since I have ARB lockers).
