Engine light on

2004 jeep grand cherokee laredo. the code says it is a malfunction in the 3rd and 4th gear. what do i do?

    Take it to a reliable trans shop. They can check it out and see if the problem is in a module or in the unit itself. If internal, there is nothing you can do with it unless you are an experienced rebuilder (but, if you were, you wouldn't be asking here!!)

    The code is specific to a system, in your case the third and fourth gear. Next step is to determine what is malfunctioning...could be the electronic controller, wiring problem (corrosion, broken wire etc) a shift solenoid or the actual hydraulics inside the transmission that may be suffering pressure loss from wear etc.Any good reputable transmission shop has the equipment necessary to do this testing.

Are you in Limp Mode? Is the Check Engine Light on?

Some ideas here including pulling fuses. You probably need an auto electrician though.

2004 jeep grand laredo MIL(malfunction indicator light)

Yes it can be caused by low quality fuel, and your gas cap not being installed properly. Best bet is the gas cap, so take it off and screw it back on. Then take your vehicle to autozone and hook up diagnostics to clear your MIL.
