Tranny stuck in limp mode

It is gearbox problem,could be oil level issue,please check level first.

What is he limp mode. you have not got enough fluid are u checking it warm and in park car has to be running to check tranny only, DO NOT OVERFILL IT LESS IS BETTER THAN OVER.

Replace the transmission control module

Its more likely the tranny shift solenoids or the power wire going to the tranny. If the tranny loses its ignition feed (12Volts) it will default into limp home mode. This means neither shift solenoid has power and will be in the off position. When both shift solenoids are in the off position this is normally third gear. It will be very labored taking off from a stop being in third gear, but will allow you to still move (thus limp home). Astro vans were not known for it, however full size pickups with the same engine and tranny, would experience a bad ignition switch. It would disable the tranny circuit and no power would get to it, same symptoms. If it sometimes works it won't be a bad fuse, best to have it diagnosed at a reliable transmission shop to verify. Its not as expensive as a tranny overhaul.

this can be from a couple of things....fill it with gas drive it for 5 miles. replace the gas cap! the last thig is that the trans need rebuilding; the seals are not working properly and will not allow the fluid to flow which does not allow for proper shifting. i changed fluid and trans filter but only got 600 mile before I had to rebuild it $1300.00

The town and country vans are know for transmission problems and it would not be stuck in 2nd gear if it was in limp mode. Limp mode typically controls the engine. I have seen people do a transmission flush/filter and add lucas to temporary fix the problem. There is also a good chance that the transmission has a solenoid problem preventing it from shifting into any other gears but second. Hope this helps!

I need a little mor info. But the reason for the being stuck in 2nd gear is because when something goes wrong with the tranny. it goes into "LIMP" mode wich keeps the trans. from shifting out of 2nd when you are going forward. It does sound like your trans. is gone out though.

try diconnecting switch to test switch . Scan Pcm for trans codes . If codes present repair them. Otherwise tranny shop reqd

I expect you are having internal issues within the tranny. There are valves within in that, from time to time, may fail. Soory to say but from this vantage point I suspect you'll need to drp the tranny and rebuild or replace with another used/rebuild.

I hope this may have asisted you,

Have u checked w/ scan tool for codes? If not, have garage, dealer, or parts store (free service at most parts stores) check for stored codes, and as u know, Chrysler is known for their c_rappy trannys,. I just had mine rebuilt at 125k (I changed the fluid and filter every 30k, but still failure). Limp mode is to protect from further damage, so something is going on. If no stored codes, drop the trans pan, check for metal in pan and on magnet, color of fluid, burnt odor? Let me know what u find. good luck
