4l69e must start in first to get going but no fourth

basic mechanic knowledge will not get this fixed. go to a tranny shop let them know what the codes are they will be able to fix it faster and correctly without further problems.

Being a 91, take it back. But this really depends on who you had build it. Shade tree guy, your probably going to eat it. Garage, take it back and make them fix it.

Of course you can, you may need a few tools such as a spark plug socket with a flex attached and a few extensions 3/8 drive but other then that it would be just like any other car. Take your time doing one at a time and wha-la you are done.
First grab the back of the boot and twist a little left and right to break the natural adhersion between the plug and wire then slide the heat shield back and pull off wire, change plug and reinstall with dilectic grease

My first instinct is to tell you those symptoms are BIG in nature and spell DOOM.. however if you are a glass half full person and dont mind trying a few things.. you have options.. IF YOU CAN turn a wrench and think.. you can get it DONE, : )

yes... are you mechanical? you can start by changing the tranny filter and fluids ( twice).. once drive it 1500 miles on the first cycle at most and new filter and fluid again... ( I did a ton of reading to get to this.. I no longer use the audo tranny fluid at 24 bucks a quart.) I now use the MOBILE ONE ATF synthetic (equivalent to the audo expected quality) 7 bucks a quart. I am on the second vehicle to take it and in both cases i didnt like how the tranny shifted and when two fluid cycles and new filters were passed through each.. I am happy with the results and still driving my 2001 A6 4.2.. Happy Happy happy.


FYI.. if you are not a fixer.. and you have to take it in.. "THEY" will not have interest in the games we play in the shade of the summer mechanic trees.. lol You will be expected to pay for a rebuilt tranny and labor. sorry.


Although.. its likely by the time your tranny starts slipping and we humans notice it.. its likely damaged.

I have read some people having a pressure regulator solenoid that is not getting electrical connection and the code makes then think its a solenoid failure.. ( consider cleaning the transmission wire connections and wiggle some wires down there.) if you have a code that points to that... then do the wiggling etc.


TAKE NOTE:
alternate story line.. There is a chance the symptoms you are describing at related to the car going into LIMP mode.. if so find what the engine error codes mean and fix / reset those first.

your going to ave to get under the SUV, look for the connectors going to the transmission, sounds like one of them is not pushed in all the way, or insted of pullling off the connector the correct way the yanked it by the wires, if you have an "Auto Zone" near by you can stop by there and they can read the codes for you for free, if you need to read the BCM codes you can rent the tool for free, or sometimes they will let you take it in front of the store to use it from 30sec or so. will at least point you in a direction.

check your local jeep forums. try Project jk. com or just search jeep forums and your location on google. Most enthuist are shade tree machs. and from experince are more than happy to help wrench on another jeep. good luck and good wheelin

Unfortunately this is not a job for someone that has to ask this question! Automatic transmissions are not something a shade tree mechanic should attempt to rebuild!

So your choices are to replace the automatic transmission with a rebuilt or new one or to take it to a transmission shop to have them work on it. I highly do NOT recommend the chain transmission shops like Amco, because they have a habit of telling client they need a complete rebuild when they really only need the belts tightened. Talk to friends and relatives and get recommendations on your local transmission shops and call the Better Business Bureau to check out the recommendations.

I am not a diesel mechanic, a tractor mechanic, or a shade tree mechanic. But, it sounds to me like it is time for a new clutch pack. Anyone with reasonable knowledge of simple mechanics can do this job at a much cheaper price than a professional diesel or tractor mechanic, but it can be a heavy duty job. I would weigh the differences in downtime of my equipment and the ability of my shade tree mechanic.

Well, defective low oil sensors is common. What are some of the codes you are getting? You have a soft 3-4 shift?
