Will a 700r from a 4.3 engine work on a V8 motor. I was just wondering my tranny went today and i need a replacement.
Thanks

 

yep. will have to change tailshaft housing should be all to get it bolted in.

 

Is it a good idea to replace the torque converter while replacing the tranny and will the converter work off from the 4.3?

 

Don't use that tranny!!! It has fewer clutch packs in it and it's valve body is calibrated to shift for a 6cyl. You will not be happy and you will break it. Call a trans shop and ask them, if you don't believe me.

 

ALL 700r4 have the same amount of cluth pacs.
my 700r4 came out of a 6 banger van, when i orders the rebuild kit i orderd it for a vette and got the same amont of clutch pacs, then i upgrade to 9 cluthc pacs. you are right about the valve body thought, but a shift kit can cure that

So is the tranny any good will it hold out for a V8 or not I have some conflicts in the replies.
Thanks for the posts

 

All I will say is this, when my 700 died not long ago I came across a good deal on a 700r4 from an Astro 4.3li, this tranny was a rebuilt one that a guy I know had at his shop. (Local tranny shop)when I advised him what I had intended on putting it in he talked me out of it saying I would be extrememly unpleased with it. I did buy another tranny from him a TH350 for a few hundred $$ less than the 700R4. So I do not know, but I would advise against it if at all possible.

Just my .02.

going to be pretty much same internally. only a few differences. i didn't see you ask for opinions on this which is why i didn't give it initially. if you need one and it's available, go for it.
