208 question

[Jthomas]

It came off my 700r4, I want to put it on a th400. Will it even work? Will it mount different to the frame? What do I need to do?

[Crazymays77]

it might just have to get a diff adapter for it

Idk too much about drive train. What addapter do I need?

[betterbeaters]

it wont work wrong spline a 208 off a 700r4 will hook to a 350th but not a 400th. but one off a 465 4 speed will work on a 400th

Could I just get another output spline?
Or would it just be cheaper and easier to get a different T case

[Crazymays77]

yeah i forgot about that lol

Wich ones better?

either get a t case off a 400 or   get a 350th   that t case will bolt on it   or     chnange output on the 400th if u know how to tear into a trans

What Tcase came off a 400? Like a deacent one.

[betterbeaters]

you can get a 208 or a 205 both are good cases. also they came with 203s but I never liked them.

Scrap yard be my best bet?

[betterbeaters]

craigslist or mabye look on here or you can try a junk yard...   or sell the 400 th for a 350th and build it and be done?

I'm leaving for beaver island tomarrow. I'll be back in 17 days. I'll think about it, I have to get my trans first.

[chevystudz7105]

to bad you dont live closer.  i got a junk 208 that has the right splined part in it ot make it work with a 400.  wouldnt take much to split the case and pull the part out. 

[Jthomas]

Do I have to change the tranny tail shaft? Or parts in the Tcase.

you can change just the part in the t case.  thats what i did to my one 208 i had.   it was attached to a  sm465 trans (which is the same spline count as a 400)  and i wanted to put it on my 350 trans i put in my truck so i jsut swapped out the part in the t case.  real simple to do

[Jthomas]

cool thanks. what part?

[chevystudz7105]

i believe its called the input gear.  its part number 3 in this pic

[timothy]

thats all I do is just change the input  shaft I have a couple 350 inputs laying around but only have 2 for my 400.  very easy to do then I just reseal them with ultra grey I have have been told I have to use right stuff but ultra grey works just fine.
