203 versus the mighty 205 well well well I'll tell you what i know thru experience i have a 460 powered Nissan patrol far from stock it is used for rock climbing hill climbs outback challengers ect i first used a 203 as every body conned me saying good tough box, if you treat your 4by like a girl then their great if you want a serious transfer then the 205 is the way to go,
You can have possibly four different ones just depending. They are NP203, NP205, NP208, and
The 1973 Dodge Power Wagon typically comes equipped with a part-time transfer case, specifically the NP203 or NP205, depending on the specific model and configuration. The NP203 is a chain-driven transfer case with a full-time four-wheel drive option, while the NP205 is a more robust, gear-driven model known for its durability. These transfer cases allow for versatility in off-road conditions and can engage four-wheel drive as needed.
10w40 motor oil 4 qts
NP203 (full time version)
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.
12 ton blazer? Wow. I think you meant 1/2 ton, at least that's what mine is.
Yes, there are 4WD automatic transmission transfer cases with a left drop that can be adapted to a 1976 Dodge 440 engine, typically found in vehicles like the Dodge Ramcharger or certain older 4WD trucks. The most common options include the NP203 and NP205 transfer cases. However, you may need specific adapters and modifications to ensure compatibility, so consulting with a specialist or doing further research on aftermarket solutions is advisable.
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.
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.
The designation is cast into the case. You'll need to crawl under there and take a look.
"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.
The shift pattern for the transfer case on a 1989 Jeep Wrangler typically includes options for 2WD, 4WD High (4H), and 4WD Low (4L). The transfer case lever is usually shifted from 2H to 4H while the vehicle is in motion at low speeds, and 4L is engaged when the vehicle is stopped or moving very slowly. The exact configuration may vary slightly based on whether the Wrangler is equipped with the NP231 or NP205 transfer case. Always refer to the owner's manual for specific instructions and recommendations.
