05-g56 in an 09

[Kent Kuykendall]

Is there any difference becides gear ration in sixth gear in the 05 g56 and 09 g56's?

From my understanding, there are no other differences other than the final gear ratio. If you are going from the 09 to 05 it might take some getting used. My early 06 tows like a dream but is wound tight on the interstate.

5th is the only gear that is the same.

1-4th at 5. 6% taller, 6th is 6. 3% taller.

1st 6. 29 vs 5. 94
2nd 3. 48 vs 3. 28
3rd 2. 10 vs 1. 98
4th 1. 38 vs 1. 31
5th 1. 00 vs 1. 00
6th 0. 79 vs 0. 74

My '07 has the lower gears. With the 34" tires,it's probably the only thing keeping my clutch healthy.

My dad has an 06 with the lower gears and tows a lot, probably 70% of his miles or more. He is at 80K on the stock clutch, 70K of which are with the Smarty Jr. .



It's amazing how well that . 79OD tows.

you can buy a g56 reman from dodge with a 5 year 100K warentee up to the year 05 but the newer ones you can buy new but only with a 12/36 if i'm not mistaken. I am almost always towing I would most likely like the lower gears.

 

[Regcabguy]

Yeah,I got one of the first Smarty Sr's released 4. 5 yrs ago approx. I'm only using sw#1 with the constant camper load. Gotta milk this dmf for awhile as home improvements are happening lately. That OFE is what I'll get.

With 285-70-17's my rpms were about 2200@65. Pretty brutal. The 285-75-17's calmed it down a bit.

Stock tires with the "AD" is about 2100, stock tires with "AE" is about 1970 at 65 mph.

5. 9's were only offered with 3. 73's and the G56, 08+ could get 3. 42 or 3. 73.

The G-56 only comes w/3. 73's



I believe in the pickup. With my trannny's high final drive it mimics 4. 10's.

 

[KLauber]

I get about 1775 RPM at 65mph.
