Sticky: Difference between a 2003 300A and a 300B

[Blackened300a]

This topic has been asked a million times, I shall break this down and hopefully this will be the "go to" thread on this question that arises quite often.

300A's were the first issue of Marauders they were all black and had the following equipment...

Auto release fuel door
In-dash Clock
Map pockets in the front seats
Full size spare
Auto Release Parking brake
Windshield tint
Hood light
4R70W Transmission
Single engine knock sensor
Black Valve covers
2400 Stall convertor


Only options for the early 300A's were a trunk organizer, rear spoiler, and a 6 Disc CD changer.

300B's came out mid year and were offered in black, silver and dark blue pearl. They had less features then the 300A so they are considered "Decontented"

Differences on the 300B are...

Heated seats
Traction control
Manual fuel door
Mini Spare
Dot Matrix on upper portion of windshield
No map pockets
Clock in radio
No Hood Light

Options for the 2003 300B's and all 2004 Marauders were a 6 Disc CD changer, rear spoiler, sunroof, and trunk organizer.

Some mid production year Marauders have been found to have a little bit of the 300A and 300B features combined.

2004 Marauders were offered in black, silver, and dark torador red which replaced dark blue pearl. New additions for the 2004 were the 4R75W transmission with stronger internals and torque convertor with most likely the same stall speed of the 2003. The Black valve covers were dropped and plain aluminum were used instead. The 04 was also given dual knock sensors.
2004's were offered in 300A but all features were those of a 300B.

I thought the 4R75W was an '04 change?

[BruteForce]

You forgot to mention that the 300A is faster.

[Blackened300a]

You may be correct but 04 model years sold in 03 so I have no idea when the tranny swap came in.
If they changed over all that stuff mid year, I dont see why they wouldn't have put the different tranny in as well.

That is correct


All 300A's are Black
Most 300B's have an underhood light.
The 2004 has Aluminum colored valve covers.

The Dual knock sensors and the stall I believe were 04 only. Also 03 had the fading down tint on the top of the winshield and B's had a dot matrix.

All 2004 Marauders are 300A.... alphabet models start over each model year... and all 2004s have M79 in the VIN distinguishing them from the Grand Marquis.. M75... unlike 2003 when they were all M75..... RAM

Would the owner of a 2004 300A please come forward.

The full size spare was replaced for a mini spare when Traction control was offered. Thats covered in my original post

Hey you gota let new members start asking questions sometime

[lastdaze04]

being the newbie amongst y'all this brings up another question sure to bring up some controvery.
What's the difference between the 4R70W tranny and the 4R75W tranny besides the difference in stall converters. Which is better to beef up, which holds up under the pounding of a S/C motor blah blah blah....

[cyclopsram]

Don't forget the park brake automatic release when drive is engaged... I believe that went away in the 2003 300A/B transition...along with the non polished wheel and full size spare tire,..... all Canadian Marauders had traction control... and were in 2003... all 300B RAM

I don't want to disagree here but the 300A I just picked up today was built in Canada and does not have TC unless I am too stupid to see it. I know its not engaged cause... oh yeah I have had it sideways all day

I believe ALL Marauders were built in canada, I think he's speaking of the ones that stayed there?

Not built in Canada, built FOR Canada. You know, dash is in metric with kph, etc...

I may have forgotten something so feel free to chime in.
Maybe we can save useless threads about questions we answered a million times over.

My 300B has the underhood light, and a single knock sensor, I saw it while installing the blower. Black valve covers as well. The rest of your list I have as stated. Good job.
