I am thinking about changing my v8 Miata which currently has a t-5 to a c-4 automatic. I do some light bracket racing and am looking for more consistency.

When I am not out on Saturdays at the local track I only use my car for pleasure and am tired of always changing gears in traffic.

Does anybody know if I can use the manual transmission tranny cross-member with this swap? I have the transmission cross-member that comes with the monster Miata kit from Martin.

Thanks for any help.

If it doesn't fit, It should be easy to modify.

Did you ever swap to an auto ?

c4s are not very big compared to a T56 that the GM guys use or the bigger autos guys put in these cars so yeah it would fit easy. My question is why use an old dog 3 speed trans when an over drive trans will fit? There are several 4 speed auto Miatas around and our own https://www.v8miata.net/members/cvx_20-220/ has one you should check out. His excellent blog is here: http://miatav8.blogspot.com/

Tbone is right trans mounts are a very simple structure and would be easy to tweak to an auto. Probably a bigger problem is finding room for a trans cooler especially if you have A/C and a steering cooler already in front of the radiator.
