Just like the title says. Bought a Stang with a 5.3 and th400. Just needs a converter now. I have a Circle D still laying around from my last build. Will it fit? I'd really like to use it if possible. Save me a ton of $$$. Thanks guys

 

No, for multiple reasons. I don't think you can use a lockup converter in a non lock up Trans. I put a non lock converter in a lock up Trans when I was young and didn't know what a lockup was, the truck made it like 75 feet before it smoked the Trans

 

I hate to break the news, but there's no way that will work.

Different pump and turbine hubs, different height, the 4L60E converter has a lockup clutch meant for a lockup capable transmission (which the TH400 is not).

I'll send you a PM, I can probably help you out with a good deal on a TH400 converter.

EDIT: Left this tab open too long lol, someone else beat me to it.

 

Sell the circle d and buy a th400 converter. Simple as that!

 

That's what I'm doing now. Thanks guys!!!

 

Looks like these gentleman answered your question. Let me know if you need any assistance with a new converter.

Will do. I'm a little ways off from actually needing it. Gonna try and sell mine first. Money is getting harder and harder to come by now a days
