Good find there

[Andyboy]

Can you put a 350 tranny with that adapter? Or just the th400?

[padresag]

yes you can put a 350 behind it or a 700r4

don't for get the 200R same length as a 350 and uses the same d/s yoke. the rear mount is just farther back. ran one in my 65 chevelle el/co with non lock up converter. good little overdrive.

I have a 62 gmc with a v6 305 backed with a auto hydramatic. The adapter I have is not the same one there selling Right?

Thanks Ron,

Sorry for all the questions but don't know to much about these 305's. What else would I need to make this work with a 350.? starter, driveline ?

[duallyjams]

It's missing the 2 support rods that go from the trans to the engine but if it sells for 200 that's a good deal as these go for 400.

what about the other way I found a gmc w/ a hydro, would a chevy motor bolt to it, or would I have to find an adapter for gmc hydro to chevy?

Guys...I might be misunderstanding the question....but I beg to differ.
If you have a Vee Six with a Turbo-Hydromatic tranny....then the tranny is a GM six bolt patterned design....and the adapter starts in front of that....and goes all the way to the GMC engine block....which will bolt directly to a GMC Truck Bell Housing.
Unless the sixty two's are different (and they might be)....the automatic adapter assembly allows you to bolt the GMC Vee Six to any standard GM automatic tranny... TH350, TH400, TH700r4, and all and any of that generation ....and if it works for one it'll work for the others.
There are two different adapter assy's....not sure what the year break is(it might be '62).
One has the round design flex plate (for lack of a better term)....and one has the triangular flex plate...like mine and the one on e-bay and the one D-jams posted.
Ya will see mine on post #85 on my build thread... http://67-72chevytrucks.com/vboard/s...d.php?t=453161.
But....they both work the same and are interchangeable...one for the other.
So yes...Andyboy....yers is the same.
But....as far as the struts themselves....they are unique to the TH400.
The tranny end will be tranny specific in all cases.

Ok rockdriller, are you telling me I have the same adapter in my truck and that I can drop the hydramatic and slap in a th350 or th400 with no problems. Except for the ones I make for myself.lol

no you need the newer one

[A.T. RockDriller]

Well, Andy....Just in case I talked my way into a corner that I'm not aware of......I will restate the whole thing....fer clarity.

If you look at my thread..."Rockdrillers '63 K1000"....or whatever it is....and look closely at post #85....at the GMC automatic tranny adapter...I can guarantee that I could bolt up a TH350 or a TH700R4 or a 4160 series auto tranny onto our BB V-6's and the only "maybe" variable, other than driveline length or electrical hook-ups would be the two struts that we are talking about.
The tranny end of those struts would need to be modified to connect to the pan bolts.
That's it.
I hope that was clear. I can't swear ...not knowing exactly what you have in front of you....what is for sure a go or a no-go....
But look closely at my adaptor. If you have one of those, it will do what I said.
You may be okay running it without the struts....I'm getting the idea that some folks have and had no problems.
Let me know.

[padresag]

thank you, i see how it all goes together now. those more than likely get thrown away 9 out of 10 times. I have see quite a few of those adaptors for sale but the rods never seem to be inc

Do you think you can make those bars, If there not easy to find?

[duallyjams]

this is copy from the 6066 forum


 This will allow you to directly bolt up of any of the Chevrolet style
automatics to your V6, the TH350, or the TH400, or any of the 700R4, the 4L60
and the 4L60E overdrives. With gas prices going ever higher, any and everything
you can do to increase mileage helps.

 Mine is identical to the one listed on E-bay and in excellent shape, but mine
also includes with it the later model engine side motor mount brackets that use
the less expensive and much easier to find Chevrolet interlocking style motor
mounts, which will prevent the engine from doing somersaults under the hood if
one should break.

 Just something to think about, but since converting to an automatic will
eliminate the 2 bell housing mounts and only adds one transmission mount, you're
going from a 4 point anchorage system to a 3 point, and the engine mounts are
the only thing keeping the engine upright under the hood. The original V6 motor
mounts are not up to task even if they are still in decent shape, once the
bonded rubber tears free from the metal on either side, the only thing keeping
the engine in place would be gravity. The interlocking Chevrolet motor mounts
would keep the engine in place even if the rubber did tear or break free from
the metal brackets. This would also prevent any kind of loss of throttle control
that could happen if the original style GMC motor mounts were used and failed.
Like I said, just something to think about.

That's some good stuff, James.

I have my adapter set up on the for sale site here ... but I don't have the bars either ... Mine is still connected to the GMC V/6 , need to get it pulled ... But thank you A.T.RockDriller for the pictures , I used one of your pictures for reference ... Thanks ...

[A.T. RockDriller]

BTW....
I just edited my previous post...News Flash...!
The transmission end of the struts we are talking about are unique to the tranny.
Mine will only bolt up to the TH400 pan bolt arrangement.
Period.
As we know, the TH350 and the 700R4 have their own pan bolt pattern, and there is only one set of struts that will work for either of them.
So....since we know...or maybe we don't...GMC offered a standard 3 or 4 speed, or a Powerglide, or a TH400....and that's all they offered (save for the M/D and H/D Trucks)...then you won't find a set fer the TH350 & 700R4....unless they were custom fabbed.

They are a pretty tight...precision fit.
If you're crafty....you'll be okay, but it won't be a walk in the park.
It would be easiest to pick some up....obviously
If you go to Jollys site and ask you may be able to pick some up for a song. They are pretty cool folks...and they'll help most anyone out.
If you have problems....PM me and I'll help you figure it out if you hit a dead end.
