What is the oil capacity for NP205 transfer case?

The NP205 Transfer case takes 2.5qts. There has been quite a bit of discussion concerning the type of oil (gear vs ATF) from 1980 on. It's suspected that the change to Dexron I later on was for fuel economy. They're virtually indestructible so any type of oil is good; unless it's mated to the NV4500. Use the same oil as the trans in case of a seal breach.

Does a stock 1977 dodge power wagon have all time four wheel drive or is it suppossed to have hub locks on the wheels?

A stock half-ton 1977 Dodge Power Wagon should have an NP203 transfer case and a Spicer model 44 front axle. The NP203 is a full-time transfer case with a locking differential in it to allow for a selection between "four-wheel drive" and "all-wheel drive". In other words it would send equal power to the front and rear axles, or divide power between the two axles based on driving conditions. The Spicer 44 front axle is not suppose to have manual locking hubs on it due to the fact that the NP203 transfer case is always sending power to the front axle.


Will a 1972 Chevy Blazer transfer case fit a 700R4 or 4L60E transmission?

No. The 72 Chevy more than likely came with a np203. You will need one of the following to mate with a 700r4 or 4l60e: np208, np231, or np241.

I have an Np203 transfer case and I want a better gear ratio to get my RPMs down what can you use in its place It is in a 76 blazer?

"remember if you change gear ratio in transfer, you will have to match gear ratios in front and rear differentials" The above answer is incorrect. I Front & rear Axle (differential) must be the same as each other, but the gearing in the transfer case can be any gear ratio you would like. All transfer cases are 1:1 ratio when in "high" range. While in low, the gearing is usually between the 2:1 (NP203, NP205, Dana 20) to 2.7:1 (Dana 18, NP231, Dana 300, NP241, NP208) range, while custom transfercases (Atlas/Stak) come in 3:1 all the way up to 5:1 range. The initial question doesn't make sense/is contradictory to me. If you are talking about lowering your RPMs while driving on the street or at Highway speeds, your transfer case is not the answer (it should be 1:1). You either will need to change the transmission to one with an Overdrive (.8/.75:1), or change the gearing in your differentials. When changing the gearing in your differentials, the higher the number the lower the gearing (more power, but higher RPMs at freeway speed), the lower the number the higher the gearing (less power, but lower RPMs at freeway speed). Now if your talking about a better gear ratio while offroading, that is the other end of the spectrum. You would want lower gears (higher numbers) in your differentials or swap out your NP203 for a lowered geared transfercase.


What does the vent tube from the NP205 transfer case from a 1979 Dodge Ramcharger connect to in the engine compartment?

nothing, it should be as high as possible in the engine bay-- it's just a vent. Hopefully it stays above the water line should you get in deep water
