Re: 83 4x4 4spd

The trans is a sm465 and I am guessing the t-case is a np205.
The np208 t- case was in the 1/2 ton trucks.
The np205 is cast iron and the np208 is aluminium.

Gun control, the theory that 110lb. women have the "right" to fistfight with 210lb. rapists.

The reason animal rights activists are more passionate about fur than leather is because it's safer to harrass rich women than bikers...

Re: 83 4x4 4spd

465-208 I own an 83 1/2 ton and this is what is in it. not bad though. Its not as strong as the 205 but it has a lower-low range gear then the 205.

2-1 in the 205 and 2.6 or 2.8-1 in the 208 (i dont remember)

The output shafts in the trannys are different 4WD vs. 2WD.

Re: 83 4x4 4spd

I don`t know what trans you want,but get a 4wd version or a complete t-case/trans combo if you`re changing t-cases,too.
