Hello, my engine light was on for a VERY LONG time and everytime I got it checked no one could tell me what the problem was because things always checked out fine. The "code" says its a loose gas cap or something, but it wasnt that. My 300M also was having A HARD TIME STARTING UP for about 8 months and leaking coolant for about a month. I finally found a mechanic who knew what he was doing; 1. Leaking Radiator 2. Coolant found in #2 or #3 cylinder. The cause of this was a busted HEAD GASKET. If your 300M has trouble starting and the Engine light stays on have a mechanic check your engine for a busted head gasket and see if all your cylinders are firing correctly. I had to pay $2600 for a new Head Gasket, Radiator and all new hoses plus labor. CRYING!!!!!!!!!!
I have a 2001 300M 130K - very well kept. Stuff happens...

The Transmission Relay is in the Power Distribution Box. It's one of the 3 smaller identical relays underneath the row of 7 larger identical relays. It's the top one immediately below the larger relays. Between the Park Lamp(Larger Relay) & Fuel Pump (Smaller Relay).
Fuse #14 is also for the Transmission Relay.

Many times on Chrysler products, one or both of the speed sensors screwed into the front of the transmission will fail, and cause the tcm to go to limp mode. Also make sure you have power to the tcm. Someone with a scanner can check these for you, or the speed sensors are less than 20 bucks each, replace them both and cross your fingers. If the transmission has internal problems, the tcm will sense this and go into limp-mode as well.

The 700 is the limp mode, as I recall. One or both of the sensors are failing, and they are not too expensive to replace. Once replaced, then using the OBD tool, you can delete the fault codes and then be able to shift into all the gears.
I have written about this solution in other blogged questions, and so have others. Under the car, on the Driver side of the transmission are two electric sensors. They lay horizontally on the trans just behind where your foot would go on the accelerator and under the floorboard. The electricl clip sockets pull out with thumb pressure on each socket. DO NOT pull on the wires EVER. Unplug each socket, and replace one at a time. Use a 1" deep well socket and unscrew them from the side of the trans casing. Do one at a time starting with the one on the left, the Input side,; Then the output side.
The reason why I replace them both is that they are cheap- about $20 apiece- and REALLY: do you want to go under there twice for twenty bucks? If so, then just replace the one on the LEFT- the Input sensor. You then MUST RESET THE CODES with the OBD tool for the transmission side of the tool, then GO!

P0700 is a general fault code for the transmission. P1776 is a fault code for the low/reverse solenoid inside the transmission. Since your problem is only present while the A/C is on, it is most likely electrical. Check your battery charge and your alternator performance FIRST, as either of these can cause this problem. Check the wiring to the solenoid, which is located at the front of the transmission. Finally, change the transmission control relay located inside the power distribution box ("fuse box") under the hood.
