Im sorry I can see how that would confuse you. It went in the shop to repair body work at about 20k miles they said there were no mechanical issues when this happened. From my story though you can see they were wrong or this was a fluke.
I've never heard of "limp mode" but yeah I gues so. The shop I took it to was Jack Wilson Chevrolet as they have the best reputation in dealing with body work and such. The local Dodge dealership toatally agreed, and there five star here in St. Augusitne.
I think it was some kind of insurance scheme or cover up honestly. I think they overlooked this and tried to pass it off on a warranty issue. The body work was all my fault[:'(].
Yeah T-dub take it from me man what im talking about is my first vehicle. I saved hard my senior year and when I graduated I bought my 03' Ram single cab 4x4 Slt Hemi. All with my own hard earned money. Then subsequently put it in the shop a couple of times almost got a D.U.I, got a reckless driving charge, blew a couple of trannys and grew up.

(all in the first couple years)
Do what you want with your money man it's yours just remember that you still want to have it years later. Words from a 23 year old hard a** worker. Peace... P.S. I learned my lesson the only way I know how, HANDS ON, or the hard way

But I do appreciate everything I have in this world and feel very lucky to be positive about my short comings. Live life to the fullest be safe and buckle up brother.
So the first time might have been from an accident from a body shop? Was it the Chevrolet dealer who replaced the transmission when it went? I have a feeling I might know what went wrong. It could have been a case of using Dexron instead of ATF+4. If that is the case, that explains everything.
Jeremiah, you are correct. "Limp mode" locks the gear in second so then you can get to safety. It generally takes place when the transmission is going out; however, it can also be the case that a particular sensor has gone out in the transmission. This happened in my uncle's '99 Plymouth Breeze. It went out around 47K, and all that he had to do was replace the sensor and it was fine. How many miles did you have on it when you replaced it and which engine did it have the 3.0L or the 3.3L? The older A604s were more prone to failure so this is not surprising.
jdb840, so you actually blew the engine on a detonation problem? Was the Supercharger partially to blame for this or was this one of those intake gasket issues? That is not unusual for those transmissions from what I have seen, but the 3800 is normally a very good engine that will last a lot better than that.
