i need the gear ratios of the dodge 6-speed. it's in an '01 2500 cummins if that makes any difference.

thanks

1st 5.63
2nd 3.38
3rd 2.04
4th 1.39
5th 1.00
6th .73
R 5.63

thank you

you don't happen to know the reverse gear ratio on the allison 1000 do you

The ratio's posted are for a NV5600 6sp which is found in the 2003+ trucks. Are you saying that the 2001 truck has a NV5600? If not, then the ratios may be different than what is posted.

they should be the same gear ratios between the various years. afaik, all nv5600's are the same ratios
