How to determine which transmission is in your LX *

**fnkychkn** · 10-07-2005, 10:08 PM

This information is found on the body code plate which is located in the engine compartment on the front right side shock tower mounting front panel. the first three digits on the bottom line are the transmission code.
DG6 = 42RLE
DGV = 42RLE with VLP (variable line pressure)
DGJ = NAG1

Is there one transmission for the Magnum RT that is better than the others?

only one transmission used with the RT 5.7L, and that's the NAG1.

Does that include the AWD models?

AWD models only available with NAG1.

as far as i know:
2005 2.7L & 3.5L RWD models use 42RLE trans.
2005 3.5L AWD models use NAG1 trans.
2005 5.7L RWD & AWD models use NAG1 trans.
2005 6.1L models use NAG1 trans.
2006 2.7L models could be equipped with either 42RLE or 42RLE with VLP trans.
early build 2006 3.5L RWD models could be equipped with either 42RLE or 42RLE with VLP trans.
late build 2006 3.5L RWD use NAG1 trans.
2006 3.5L AWD models use NAG1 trans.
2006 5.7L RWD & AWD models use NAG1 trans.
2006 6.1L models use NAG1 trans.

Thanks FC... Interesting that the AWD and RWD models have the same tranny... I would have thought a different model would be in order... but guess not.

same basic trans but i think the tail shaft/extension housing might be different. never had that close a look.

Does anyone know if the NAG1 is a direct bolt in/upgrade for the V6 cars? I assume it would be, Im just making sure. Does anyone know how much power these trannys can handle?

This brings up another question: Since the newest SXT models are said to be using the same transmission as the R/T, how can one be certain that the car does have whe NAG1 transmission?

Correction

2006 3.5L RWD Uses only NAG1 trans across the board. 42RLE is only with 2.7 from now on.

Another easy way to tell your 4speed from 5 speed is to look for the autostick shifter in the car. The 4 speeds have PRND3L the 5speed only has PRND

It can handle upto 420ftlbs of torque maybe even just a little over that for overhead protection.

What exactly is VLP? What is the benefit? Thanks fnky! You da' man!
