whats a 400/205 worth?-

[beater_k20]

not looking to sell, looking to buy for my K20 to replace its current 350/203.

a guy at work said his buddy had a TH400 with a transfer case out of a late 70s K20 that he wants to get rid of. what are these things worth as just a core? i wanna make sure not to get screwed on the deal.

I think the 1st year of the TH400/205 was 1980. All 1980 GM 4x4's came with 205's, but before that the TH400's had NP203 behind them. So if it's an original late 70's, it may just be another 203.

For a true TH400/205 combo, I've sold them for between $450-$700 for the pair, and I'm sure others have sold/bought them for less and more than that price range.

i thought the 350/205 was the rare '80 only model? granted, i could be wrong, but there are an awful lot of guys around here with a 400/205.

All 1980 Chevy/GMC fullsize 4x4s had a 205... SM465s, TH350's and TH400's. They were all slip yoke T-cases too, unless you happen across a true 1-ton Crew Cab, then it would be a fixed rear yoke.

The Suburban I recently got for $350 I mainly bought cause it was a 1980 and had a TH350/205. It was a 1/2 ton, but had it been a 3/4 ton 1980 it probably would have had a 400/205.

Early 1973 trucks also had the TH350/NP205, until they started going to the 203's in late '73... '74 model year. They were fixed rear yoke.

Then of course, anything after '81 (through '87/'91) only had a 205 behind either a 465 or TH400 if it was a genuine 1-ton 4x4... regular cabs got slip yokes, crew cabs got fixed rear yokes.... 3/4 ton and 1/2 tons got NP208s (or 241s).

i paid $600 for mine, it was a little more than i wanted to spend but it is what was available at the time locally

I agree with Alan prolly a 203.

I just sold a matching pair out of an '86 cab-and-chassis for $700. And it had the fixed yoke, too.

My very first truck was an '80 3/4ton reg cab longbox. it was a th350/205, not a 400.

 

[mountainexplorer]

Not all 3/4 tons had 400's in trucks... but quite a few did. On that Suburban, I figured if it was a true 3/4 ton it would have had a good chance on having a 400 but not guarantee'd; it could have been a TH350 as well.

 

[beater_k20]

that's pretty obvious. my '77 K20 has a factory 350/203, as did my '79 K20, and my uncle's '78. this is definitely a TH400, the guy knows his trannys, just not transfer cases.

at any rate, what i am looking for is the value of a TH400/NP205 combo, not the question of wether it is or not a 205. i can easily determine that myself within seconds of seeing the unit.
