I was told there are 1" and 7/8" input shafts on 4l60e transmissions depending on application but can't get the search to cooperate with me to find out which is correct...

do Yank aftermarket converters come in either? On the site I see no option. My transmission is a 98 4l60e from a 98 camaro to the best of my knowledge...

You have a 300MM shaft for an LS1 application. Just give Dave that info and he will hook you up!:nod: Your input and stator shafts should look like this.

The 4L60 has two styles of input shafts. They are both the same 30 spline though. The difference is where the lock up o-ring is located. You have the LS style like Vince shows.

On a side note, be glad to help you select a converter. We would love to make you another Circle D raving fan. :burn:

so then all lsx based transmissions have the same shaft? it was just earlier 4l60e that were different?

I have a Yank converter sitting on the bench now. But before I pull my transmission I need to know if there is any possible reason this converter which was in an 04 GTO would not mate to my transmission so I can get a different core or the right parts to have it built on hand. It is a tight fit and my exhaust will have to be removed or cut off and once the transmission is out my car will be down until it's ready to go back together.

The engine/tranny combo is a 98 and supposedly had under 50k miles on it when I bought it. The transmission had the fbody style tailhousing on it.

You should be good to go. The only LS based car that is different is the Corvette. The GTO and 98 F-body use the same trans. Good luck with the swap.

^^^^except 2005^^^^^ Only one year used the 300mm input and it was a 4l65e for the C5.

Good point Vince, the 2005 C6 A4 also had a different bolt pattern.
