Let's ask the experts. I've seen articles either way for swap between M46 and M47.

Articles here yet also the specialty of turbobricks. Access to some imnformatrion like modding and performance.

You can change to M47 to M46. Both are rare like hen's teeth. And a Tremec T-5 out of a V8 Mustang may need some serious work as would an M46 from Turbo 240, 740, 940.

Try and find an M46 from a normally aspired (or aspried? ha!) 240. M46 from a 740, 940 has a longer shift assembly. Clutch bit are different. Yet you can do it.

M46 can take more horse power yet at nearly 40 years of age, you'll have some wear item issue like the overdrive hydraulics unless already serviced.

I've not done such a task. Hope this helps you.

M47 images with silver sparkles? What ground up? How many miles? Modded B230 with Turbo or ? Drifting? Wong fluid? Amsoil Super Shift works well as does the Volvo synthteic and Redline MTL. What happaned?
