Gear ratio Q....
I just bought a 2006 Dodge 2500 Cummins Diesel quad cab with a 6 speed manual tranny.
I looked and looked, but cannot find what my gear/axle ratio is. Where would I look to find that info??? I believe there are a couple of options.... 4.1 and 3.73 ????? Any help greatly appreciated.[coffee] |
Yup, those are the ratio options for a 3rd gen.....
If you post in the 3rd gen engine and drivetrain section you will likely get more hits.....not being a 3rd gen junkie, I'm not not sure where the build sheet/sticker is located. FWIW, on a 2nd gen and depending on the year, it is on the under side of the hood near the latch or inside the glove box door. |
Glove box door.
|
I thought that all Getrag 6-speeds have 3.73's from factory?
|
we've discovered that DC quit putting the option sticker in the glove box door.
|
Yes, if its a 2006 with 6spd , then its a 3.73 rear end. The 4.10's are not available for a G56 truck.
|
STOCK03. The G56 is NOT A GETRAG.
|
So it has the 3.73???
That is the best combo for good gas mileage correct?? What is a "getrag"???? What is a G56??? Sorry, I am new to these terms LOL![duhhh] Thanks for the help! :D |

What is a "getrag"???? What is a G56??? The Getrag was used in the older Dodge Cummins trucks. Not sure if it was in First Gen or Second Gen. |
Due to the G56'S lower overdrive, the 3.73 is the only option, it is effectivley like having the NV5600 with 4.10's
|
Getrag is a first gen 5 speed and not too strong from what I hear.
NV4500 is a second gen. 5 speed (replaced the get rag) NV5600 is second and third gen. 6 speed G56 is the newest third gen. 6 speed with a lower (higher numericly) overdrive ratio and also a lower first gear ratio (IIRC) Hope this helps. |

Excellent info! Thanks for posting that! I was getting lost with all the #'s jargon!! LOL!! :D[duhhh]

Too bad they had to use 3.73 only with the G56 just because of the OD. All the other gears will be higher overall ratio and farther apart instead of a lower granny and closer splits of a 4.10. Craig
