Tranfercase troubles- NP208 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

INTIMIBLAZER · 12-19-2003, 04:12 AM

I posted on the parts board that i wanted to buy a new t-case for my TH400 which had a 208 (input 32 spline 1 3/8" shaft)

the 208 went south for the winter

I have another 208 but it is for 700R4(input 27 spline 1 1/8"shaft)

I was hoping someone might be able to tell me if the input shafts could be changed and if so how hard is it to do ( I really don't want to try this right now because I don't have the time to allow for errors or delivery if seal kits) and if I should need to take it to someone how much would it cost to have them do it and what is the average shop turn around

I need to do this as cheap as and as fast as possible being that it is Christmas and I am laid off and this is now my only ride

If anyone local would like to rebuild it fo me maybe we could work something out I do have some good parts laying around

Thanks in advance guys/girls ,Keith

You can change the input to the turbo 400 spline. You can also look for a 208 that was behind a 4spd they have the same spline as the 400. Its not hard to change them out pretty much you just have to split the cases apart.

I thought you were talkn about the 208 transfer.

INTIMIBLAZER · 12-19-2003, 05:38 AM

yes i was but when you said they were mounted behind 4speeds
i was trying to find out what years or what model 4 speed

the last tranfer i got to go behind my turbo 400 came from behind a sm 465 that was in a 1984 3/4 chevy. The 208 didn't come out until 1981.

forgot to state that last transfer was a 208. I don't know if all the 4 spd from 81 up that were mated to a 208 had the 400 splines but all of them I have had or came across had the 400 spline.

thats good to know the junkyards around here are gettin like pep boys if it is not stock or in the computer they are lost; haven't they heard about a hollander book

I know thats what I was up against. I needed a 208 to go behind my 400 so that was what I was looking for, if I found one they were pricey, then a friend showed me that the ones from the 4 spd were the same just change the adaptor. Then I found lots of 4 spd transfers and a cheaper price.
