I looked but could not find what i was looking for. I have a 06 6spd G56 tachs to high old news right. Well i would like to swap out for a NV5600 is that the right number? I know its in the older DODGEs 3RD,GENs, If so what am i looken at and would it tach lower?
I would like to tach, below 2k at 70mph!

THANKs I know im a for asking.

 

Maybe I’m wrong, but I think the 6th gear ratio in the 6.7-2007 trucks with the G56 have a higher ratio?

I also saw some rumors about taller gears coming available from the aftermarket.

I guess you could put in a NV, however those transmissions and their parts are hard to find.

Taller tires will drop a few RPMs too. (I didn’t want those because it seems they are harder on the front suspension and in some cases get you the DW)

In my case I bought the Gear Vendors OD unit. I couldn’t handle driving 55, or screaming unloaded at 2300 RPMs down the freeway for hours. In OD it drops 500 RPMs.

I’m happy with my GV, however it is expensive so had gears been available I might have jumped on them instead.

 

I guess you all ready have the bigger tires, didn't read your signature.

 

Lift it 2" more, 37s, and swap in a nv4500

 

Im game on any good ideas right now like you said driving 55mph when 70mph is posted!I would like to buy one GEARVENDER but thats big money! What is the other TRANs,CALLED in the 3rd gens?

 

The other trans in the 3rd gens are the NV5600

 

I would wait till someone starts making parts for the NV5600 before I would swap heard there where guys waiting months for NV56 parts, with out their trucks too

I would just wait for some after market gears
I love my G-unit since I changed to 315's(tires) I think it is perfect now.

 

How much lower does NV5600 tach, copaired to G56? Say your runing 70 mph.

 

2000 RPM is 80MPH for me

 

I don't know why anybody would be having trouble looking for parts for an NV5600. Standard Transmission & Gear have tons of them. I'm sure other places like TransGear would have them as well. I've not heard of any shortages of parts. I just rebuilt my NV 4500 but was considering swapping for the NV 5600 and they were ready to ship one straight out to me. A buddy of mine just rebuilt his NV 5600 and said he had his parts in pretty quick.

 

There are modifications to be made if you try to use the NV5600 in place of the G56. I'm not 100 % sure of what all it takes, but a guy that pulls locally busted 2 G56's so he retro'd a NV 5600 in it's place.

 

Ramble, what are you taching now at 70, I was looking to put on 35's for this same reason. Did it not help?
