CA NP241/TH400 or 4l80 adapter - OBO
- Thread starter Jumppr
- Start date
While the bolt pattern is identical, the index diameter is slightly different between TH400's and 4L80's.
A TH400 adapter won't bolt up to a 4L80E, the index is larger. They physically won't go together.
You can bolt a 4L80E adapter to a TH400 but the two won't line up correctly, the 4L80E index is smaller.
FYI

Thanks. I didn't know that. This adapter came off a '99 1-ton with 350/4l80/NP241.
