OD auto (700) and transfer case questions

how many spline input is the 208? Am thinking about maybe trying to use a 700/205 combo if possible in the future for a burb. :thinking:
 
Auto mated 208's are 27 spline input , 4 speed mated 208's are 32 spline input . They both have slips on the rear that have 32 splines for the slip yoke rear driveshaft to slide on :k5: :k5:

so the 700 output shaft would be a 27 spline? and the 400 is a 32 spline right?
 
205 auto and 208 auto have the same thread count dont recal what it is. you need to put the 350-t short shaft in the 700 any way to be able to mount it. The 700 has a longer shaft by like 3" or so if I remember right. I have a 700 bolted to a 205 now and I seperated it from the t-case I used this cheap adapter its like a 3'' aluminum spacer It didnt work well for me some other guys on here are runnig the same spacer with out any probs but you would have to ask them what they did. this install will require new drive shafts because the 700 is a longer tranny then the 350-t
hope this helps a little
 
so if you had swapped the 350 short shaft into yer 700 you wouldn't need the adapter? Or did I get confused?
 
we didnt have to swap anything when we went form 700 to 350 in the 82 with 208

and also not in the 80 with 3 speed manual when we went to th350

so i dunno,,

Forgot about the th400 , but in our trucks ( i.e BLAZERS aka K5's ) I don't recall a th400/208 as stock :dunno:

tail shaft is not the same internaly as 700. need special shaft. 350/700 small spline. 400/4l80/round pattern stick big spline. and the spacer worked great for me. had to use a short shaft 2x4 th350 and cut , rebevel end of shaft then spacer. ran for 3 years hard core street and offroad. 700 may be same setup for 2x4 but dont know for sure.
 
another ? The 4l80 is the same as a 700 right? and what did they come in? I am looking for non electric stuff. :waytogo: also whats the diff between the 208 and 241?
 
I have always heard that there is not a SYE kit for the 208, but I found this on arizona drivelines website :dunno: :

Slip Yoke Eliminator (SYE) Yoke
for the np241, np205, and np208 slip yoke type transfer cases

This is a fully splined 1 7/8 inch seal surface diameter slip yoke only. You can bolt this one on after drilling and tapping a hole at the end of the output shaft.

Any slip yoke transfer case can have an SYE made for it. This includes Dodges, Fords, Chevys,.. As long as it is a slip yoke, it can be eliminated.

Here is the link: http://www.arizonadrivelines.com/drive_shaft_SYE.htm
 
that reminds me there is a fixedyoke tcase for sale in the sale form its a 208 for small spline and it was made using gm/dodge parts. he got it that way and dosnt know how to do it and wants to sell it he did somthing else.

Yes that kit exists , then you need a new CV/regular yoke to mate to it . It isn't preffered though , drilling the shaft :k5: :k5:
 
Also could someone please explain to me the 4l80. What can I find that in? What transfer case was used with it? Is that the 4sp OD? I am looking for an OD setup for a burb w/o electronics, to get a little better milage than I would with a trusty ole th400 setup. Looking at options. thanks. I apreciate help. I am still learning all there is to know about chevys :waytogo:
 
4l80-e is 4 speed od version of 400 and all computer setup. well worth the money in my trucks. but 1st gear is a dog.
