code readers really dont give much info. teh trans computer is where you need to be not the pcm the pcm codes are minimal where if you access trans comp. u'll get a lot better answers to the problem. i was trolling around ebay and found some really nice afordable scanners like monitor4000 these will let you read cvi's do clutch tests and much more. the snappy mt2500 is also awsome to own. i personally have a snappy solus and love it. but i putter around with other stuff besides mopar so i need something more universal.
hopefully this op doesnt have a hissy fit about telling him he needs to get it scanned or needs the right tools!

 

And before you do everithing, just in case, unplug the main big cable on trany, with bolt on center, and look if they are comletley dry, and out of any moisture. On my van's trany moisture was causing LIMP mode, in that big plug, so i did blow with compressed air, and error code P0700 gone for good. I have learn error code P0700 is only for short in solenoid pack, or in wireing to them, or in plugs, on trany or TCM, that's all. Only shorted wire can cause LIMP mode.

But about the rest of it. i have feeling that's is the clutch discks are worn out.

 

Happy to report that I picked up a reman solenoid on ebay and put it in today. Seems to have solved the problem. I took the van out for about a 10 mile ride and did not experience and skipping or hesitiation whatsover. Yay. Prior to that it wouldn't even move in the driveway.

However, the van is what it is and the service engine light is burning brightly so the problems are far from over... but at least it is 'driveable' again after 5 weeks! (at least for now...)

 

PO303 is the code still locked in. So I will take Master Techs earlier suggestion and replace the # 3 sparkplug and wire to see if that clears 303.

 

just wondering... were the 3 transmissions you put in it new, or from a junk yard? also, what atf fluid are you using? dodge calls for atf +3 in these years, but that is now replaced by atf+4 in all. i know the neon transmissions can suffer severely from using the wrong type of atf fluid.

i dont necessarily think changing fluid will fix your problems here, but im just wondering about the frequency of your transmission woes.

you might read this for more on the importance of atf fluid in newer chryslers.

 

I doubt that that the neon transmissions will suffer severely with the 'wrong' fluid. I've installed shift kits into the 31th transmissions and the maker of the kit recommends using type F. Well the units I did for some turbo neons have held up fine with Type F. I did nothing else to the trans other than the shift kit.

 

The a604/41TE is not the same as a 31TE. You need to use the correct trans fluid. Chrysler has a TSB on this. The onlu fluid that has proven to work in these transmissions besides ATF+4 is AMS Oil. ALL others will cause problems.

It seems redicules but you will find this documented everywhere. Early on Chrysler even told owners that Dextron was OK and even had it stamped on some dipsticks. But they changed quickly to only specify ATF+3 (early) and ATF+4 (late) and then now specify only ATF+4.

 

there aint no 31te trans 31th yep. i use nuthing but dex in all my trannies and aint never had one go bad ever. my intrepid has 212,000 miles trans fluid last changed at 120,000 and she's had only dex in her. i dont care about all the hype, to me its all bs and i'm gonna just keep doing my cars with dex it works just fine and i can prove it.

 

i guess you're luck is better than mine. what year is the intrepid? i dont the model no., but the 95-99 neon and sebring autos are junk, and are known for going bad long before the rest of the car. in this day and age, its pretty much impossible to find a used one that is any good. the neon i used to have went through its original, and a used one out of a totaled car with about 80'000 on it. i always serviced them on time and used the right fluid, but they just fell apart. i finally bought a new one from advance auto for $1'100, and it held up. but i do live in WV, the mountain state, so the trans gets worked pretty hard, especially if you compare the terrain to most other states.

 

That's weird, the internals of the 3speed neon trans is exactly the same as the K-car/Omni, Minivan etc. I have some agreement about the 'right' fluid. if it was really all that great, why a do they fail so much? I rarely have problems with FWD GM cars or any imports. Also, seems knd of strange to spend $1100 for a transmission on a Neon compared to other posts you have?
