    thundergod not sure when fluid was last changed.We just bought the jeep we changed the fuel filter today.We have told the dealer we bought it from about the issue and he said that we would change it for us in the coming weeks.But our concern with that is that it may do more damage when we do.

If the dealer has previous service history It would be good to look at it. If they are willing to do the service, are they taking care of it for a charge or in an effort to correct the problem? When buying from a private individual, they can sell you anything, in any condition. Dealers must offer a working item and stand behind it obviously not as long as a new car, but if just, means very recently, you should have certain rights. I suggest you do as they tell you and document what they did and why in case this does not turn out well.
Certainly hope it does!

    Before you get yourself into trouble, check your fluid level hot. If it's not full, top it off. There are several things you need to know about your transmission. shifting is controlled by the valve body (the mechanical brain center) this is done by regulation and directing of pressure to the appropriate parts that represent each gear. These parts rely upon hydraulic pressure to engage, and remain engaged without slipping. This job used to be done only by mechanical means. On today's vehicles, part of this job has been taken over by electronic shift modules that operate small solenoids attached to the valve body. (more precise, but more complicated and prone to failure) However, the problem you reported is usually traced back to pressure. On your throttle linkage, there is usually a cable that controls transmission pressure. If not adjusted correctly, it can cause early, late, harsh or "sloppy" shift points. If internal pressure is low, or bleeding off (due to wear of any internal seal), then regardless of that adjustment, shifting will not be normal. Depending upon where the seal is, it can cause pressure loss when hot, or cold. Where cold shifting becomes normal, the seal is located where a temperature increase can change internal clearance sufficiently to regain pressure. (inverse is true where slipping happens when warm not what you have) Internal pressure is determined by the condition of the pump and governor (small device with fly-weights that allow passages to open at certain pre-determined rpm) This can also determine when shift happens.
    Assuming everything inside the transmission is in good condition, all these controls and valves work well. If a small amount of varnish builds up on any of them, they can become sticky. Once warm, the stickyness goes away somewhat just like cold honey is stickier than it is warm. So, cold, it may hold a valve from moving properly. A partially plugged filter can also influence shift points by slightly lowering pressure. (why I asked when fluid was last changed) A fluid change will eliminate the filter problem and new fluid (which has a lot of cleaning agents in it) generally will dissolve any varnish, clearing up minor problems.By making any adjustments without knowing exactly what the real internal problem is, you can do more harm than good. If you have a chrysler based transmission the only band you can adjust is either the first / reverse band or the kick-down band (can't remember which) neither of which will change the shift point where second gear comes in. AW trasnsmissions have no external adjustments.
    Attempting to make adjustment may also give the dealer the option to refuse responsibility for the problem. You could make a slight cable adjustment to see if it helps, but remember your starting point, and be careful to not damage anything. As long as the unit is not sliping it's doubtful that any harm will come from driving, especially if you continue to "lift" to allow shift to happen.

The first thing you need to do is have the Front transmission band readjusted. The adjustment is done from the outside of the case. The front band is for 2nd gear.

    To Adjust the Front band (Kickdown band) the adjustment screw is o the drivers side halfway up the case near the bellhousing. Loosen the outside locknut while holding the inside screw. Loosen the locknut about 3 turns. Tighten the center screw to 120 inch pounds. Then back off the center screw 2 turns. Hold the center screw still and tighten the locknut. When I'm don't this I alway mark the center screw with white out to see how far I turn it and to make sure it does't move to much when tightening the locknut. The two turn aren't 100% critical. If it moves a little bit when tightening don't worry about it Just as long as it's close to 2 turns. 1/8 of a turn either way won't matter.

What are the symptoms of a speed sensor going bad on a 1997 jeep grand cherokee laredo 6 cyl.


Since alot of things rely on data from the speed sensor you will "usually" get an ABS alarm, little or no shifting,no indication of speed on the speedometer, and the check engine light. without the abs light and with a speed indicated I would lean toward a transmission problem

I have a 2000 Jeep Grand Cherokee. I just replaced the transmission fluid in it and the filter as well, using the recommended fluid because the transmission was having a hard time going from 1st to 2nd...


They way you replaced fluid is bad, you should of done a bg service, by dropping the pan theres still oldoil ,the converter is full and the lines and the cooler and inside trany, then when new fluid is added the cleaners in it loosen all the dirt and seend it through the trany, the bg flushes 100% of the old fluid so no mixing of old contiminated and new oil is taking place.

My 96 Jeep has trouble shifting from 2nd to 3rd gear.The rpms go up to 4500 then it shifts.


That sounds like the 1st thing to check is the transmission fluid.Start the car ,warm it up,now shift through all the gears and stop in (N).With the engine running,check the fluid level.Top up if needed.If you do,look for leaks.Hope this helps

2000 Jeep Grand Cherokee shifting problem from 2nd to 3rd


Check the kick down cable. If it sticks the transmission won't shift. I sprayed WD-40 on both the top and bottom connectors , and it worked like a charm. It's alot cheaper them spending 2000 on a new transmission you don't really need.

Check the condition of the tranny oil on the dipstick. If it's black and smelly, the tranny clutches might be worn out. Make sure you have enough fluid in there first. Check the fluid with the car engine running and the tranny in park. The level should be between the 2 marks.
