Switching from AOD to C4 Tranny

If you're doing it just for strip, it makes sense.

For street, you're losing both overdrive and lockup.

The AOD can be made to hold lots of power,
or you can go to a late model 4R which already
has all the hp goodies Ford has developed over the
years for the OD transmissions.

Here's some info

(I'm working on an AOD to 4R swap right now, just
have the control issue to work out)

macxx1@excite.com if I can be of any help

By all means, go to www.tccoa.com and look
in their tech section, for transmissions, and
read especially the first 3 articles.

I've got some info written up and some copied about switching from a C-4 to an
AOD, but that should help you figure out
what all is involved, just reverse the procedure.

I think if I was going to buy an new C-4 it would be from PA. As far as the conversion it's really easy. When I swapped mine the only problem was cutting the welds on the crossmember. Other than that it is just remove the AOD and put in the C-4.
