Automatic to Muncie 4 speed swap
I have been searching the forms for a thread that would try to help me with a swap in my 73 corvette with a automatic to a Muncie 4 speed. If someone know of a thread or link that would give me a step by step idea that would be amazing. I would imagine it has been done before by a number of people. I am looking to see what parts I would need and if it would be a simple bolt on (being they came factor with 4 speed) or if there is heavy modification needed to make it work. Any and all help is much appreciated thanks guys!

Check the posts over the last two weeks. There is a guy with a 73 BB looking to convert to an automatic. Sounds like a match made in heaven. I had looked at this conversion for a 69 and it was relatively simple.and I put a list of the things I remembered from my research on that post.

Go to Silver Sport Transmission and pull up the parts list they show that is included in their kit to do the swap from an auto to manual.
This should give you an idea of the parts needed to do a full swap.
They will sell you the parts you need without purchasing the full kit or if you don't purchase their transmission.
They also have a link to the installation manual to do the swap.
This should give you an idea what work you will need to do.
