4l80e/203/205

[1967k10]

I'm trying to find some info for a guy who has this idea in mind. A 4L80E/32spline 203/32spline 205.
I'm not familiar with the 4L80E/205 adapter but I'd assume you would need that and redrill the face on the 203 but not sure
Any thoughts on how?

You can use an NP241 adapter and slightly modify a couple of holes....

This is a previous mock-up I did with a 454BBC/4L80E/NP241 Adapter/203/Doubler/NP205.

Pretty simple and using the 241 adapter is a lot cheaper and simpler than sourcing some obscure 205 "1 year only"-type adapter.




BTW -> I still have that modified NP241 adapter sitting in my garage if you want to make life easy for yourself. Send me a PM or whatever.

could you also use a th400/203 adapter and add a spacer or something? i think the output shaft on the 4L80E is longer than the th400, but im not positive

More along the lines of a 205 to 4L80E but there is a little 203 info in it
