ok I know , I got the pan pics and it looks like a 350 .In the drivers side it has 3 lumps like an egg cut from end to end and 3 halves were embedded in the side of the trannie 1 above the others 3 in a row...I have another one here and it doesnt have them on it.. plus it is all one piece tailshaft is part of the case ,no tailshaft..does it matter if you use a torque convertor from a 700R4 or a 350 .I put one on and tried it and the truck worked anyway ,They all look the same to me haha..Is there anyway to tell which is which..Bruce

you shouldnt mix and match torque convertors :o
-
What the lumps on the side meant, if and I have 6Torque converters here and 4 are off 700r4's and 2 are off the 350s ,cant tell the difference between the torque convertors .Will either one work with the 350 transmission.. Thats about it , i fI cant figure which is which Ill keep tryin them till one doesnt work and then back to the last one It must be the 350 one , this could take all summer haha Bruce
-
I know ya shouldnt mix them up but thats why im here HELP I ready to put it back in..

What the lumps on the side meant what? ??? ??? ???
The TH350 is a non lockup unit. The 700R4 has a lockup piston clutch inside the torque converter.

ill take a pic of them today .. bruce

i found a couple numbers on a sticker on one of the TC's..DG5E

ok I have 6 torque converters , 2 are off th350s and 4 are off 700r4s , I looked at them foir 2 hrs and happenned o notice there are 2 differences . the 2 th350s is installed with 3 nuts and bolts , the 700r4s are installed with the bolts screw right into the torque converters.. the other differenceis where the seams are th350 has one near the outside 1 , that section goes over the top and down the back the 700r4s have a raised section too but then it goes from the raised portion to the back its a longer run from the seam....Bruce pretty hard to see it unless you have the 2 together..Thanks Bruce..... Ill start puttin the motor in now Yahoo!!

haah i sated a 83 c-10 just to moreo r less to make it look nice not a show car , It had an old straight 6 in it , motor was shot so i found a 350 out of an 85 put it together with a 700r4 tork converter , surprisingly it worked but seemed to slip a bit and i knew the trannie so it was good , then i put some lucas engine builder ot whatever it is and it changed the color of the oil but was close to what water looks like in the oil , I wasnt sure so i yanked it and am puttin a 010 out of a 77 pu in it with a th 350 I had here .Ive added spotless bumpers on it for 40 dollars to now u know my budget haha it needs a seat and dash pad , Prob get a newdash pad beel lookinat alot of used ones and they were all bad same with the seat, but I have a welder and a couple Cadilac buckets ill put in it .hav a guy that will do the body work and paint it for My old 84 estate wagon no motor or trannie ,thats the 350 out of the wagon , neede some valve seals bit of a puff on startup .I had the inspector drop in and told me to cleanup the yard haha been on the todo list but its done .still have half the roof o shingle this year , did the back last year.next year Ill do the garage..The young fellow graduated last week and the old woman left haha anyway u shouldnt have asked hehe.. Later Bruce

-
Hey bruce good sense of humor you have ;D. I learned something from you though, I didnt realize 700r4 torque convertors only used bolts and th350 used nuts and bolts. 8)
-
where the nuts were the left a mark whee they were.I think they may have have clips over the bracket but cant find and 3/8 ones so maybe they just bolt on , thats quite an operation tryin to get washers and nutd in the smakk spaace and bot them up , would be easier if they had bolks to screw into gonna take a while but what ya got to do ya got to do hahaill freig with them today iLl load them down with locktight..
Bruce
ps got pics of the lmps on the th350 should have them on today ..sure wold like o know what their purpose was..
-
Just got the lumpy pics .Not to figure how to get them here Jeese
-
Heres the other 350 seems a big difference..bruce
-
hahahaha piss on it Im puttin in the 700r4 and movin the transmission mount back Hopin theres holes haha Ill get this thing together if I die under it ...Bruce
-
I couldn't understand a lot of what you posted, but I don't see a TH400 in any of the pics. I do see a 700R4 and a TH350 though...
-
thats not a 700r4 its a version of a th350 came off a 6 cylender truck..Thats lumpy hehe I got it to fit and got it in,just startin to put driveshaft etc in it, then the wirein may get it runnin today or tomorrow .
-
The 3rd picture that you posted labeled " th350lump other side.jpg" isn't a TH350, it is a 700R4.
-
I wonder , did hey put 700r4's in trucks with 6 cylinders ,My other 700r4s dont hve lumps and have a 4 pin connector on one side , the one you think may be a 700r4 has same pan on it as a th350 I dont know just want to get one workin ,Both had different looking splines on them the blue th350 has splines right to the end and the lumpy one has a tit on th e end that goes into the TConvertor..
-
Generally speaking 700R4's were available behind 6 cylinders. TH350's with a 4 pin connector on it is a TH350C.
The transmissions you have pictured cannot have the same pan as a TH350, the 700R4 is square where a TH350 is square with a corner cut off on the passenger side.
-
Yea it must be a 350c the 4 pin connector is just a half has 2 connectors and only uses one that must be what it is haha I dont know fer sure what it is but it fits .And the wire is connected , I wonder when they started useing them , Its bigger than the reg 350 too .main body is a bit longer but not as long as the 700 r4 .I only found one torque converter that was different and it was alot narrower easy to notice and have to use a bolt and nut on the olt holes whereas the 700r4s have a bolt welded onto it. I have the narrow one which i figure was on the reg th350 and I have another one that has the seams just opposite of the 700r4s high, low, etc so that one must be for the 6 cyl one thats the one I put on it anyway .it worked on the other motor should work on this one .
The other 350 I took out was workin fine till I put 1/2 qt of Lucas engine fixer uperor sompthin like that , the oil turned brown so I pulled it till I can check it out .and stuck an old 010 in till i find out whats wrong with it , dont think it blew a head gasket or somphin but ya never know.Didnt bubble or sure wasnt white like it had wter in it .Didnt want to get stuck somewhere over heated eh so when i get this one , goin Ill yank the heads off the other one .. had 261s and i got a set of 624s Ill put on it. If I can get mad enough at it Ill put a cam in it , needless to say Im not a mechanic but Im learnin fast haha Actually its fun ,especially when sompthin works , and you will prob see me on here again haha Later Bruce
-
well finally got the 010 in and running , not to put new trannie lines and brake lines on it .have to get ready for saftey check , up here ya have to have all brake lines steel others can be copper All lines myst be clamped no lss than 3ft. , cant have any holes in body , frame or floor also any holes in upper or lower control arms have to be replaced if theres a pinhole .Same for the box , no holes , S o Ill have to go all over it befor I tke it for a sicker .Pre 1987 dont need Cats. unless they are computerised..Most of the stuff is up to the mechanic So I went to talk to him.Not worried about the holed it will b painted by then ,...Bruce
-
..soo..what you're saying is, if you have any rust anywhere on the truck you wont past inspection?
-
Not really just the holes but its up to the discrepency of the mechanic if its very thin.. bruce
-
rust = holes..I dont consider surface scaling/rusting to be real rust.
