I have a '99 dually with the manual 5-speed. I think that is the NV4500. Can anybody tell me what the gear ratios are for this trans.? I think 4th is 1:1 and 5th is overdrive, but I don't know what the ratio is. Thanx for any help.

 

1st is 5.61:1
2nd is 3.04:1
3rd is 1.67:1
4th is 1:1
OD is .78:1
R is 5.61:1

 

Thanx alot for the info!
