HELP! 4L65e 4x4 to 4x2 Converstion. How do I tell if done right?! Please help! I'm sure someone can tell at just a glance. I purchased this 1955 Chevy project w/ a 2005 LQ9 and 4L65e from a 2005 Escalade (w 60k miles). The guy I purchased from had the tranny converted from 4x4 to 4x2. He replaced the tail housing, etc. He specificially stated that he took the tranny to a shop and had the conversion is done, however I spoke to a friend yesterday and he told me you can't convert a 4x4 to 4x2 without replacing the whole case (due to the input shaft lengths.)
So, how do I tell? Is the case a 4x2 case? What can I do to verify this work was done correctly (short of disassembling the whole thing?) I'm hoping they did not just change out the tail shaft housing and call it good for a quick sell.
My perception from the guy is that the work was done correctly. He called me a week later and asked to sell him the drivetrain back for another project. The car is a very complete conversion with harness, pan, computer, etc all completed.
Here are a few pics. Any help is greatly apprecaited to verify this is correct for 2 wheel drive application.
Thanks!

I just rebuilt a 4x4 trans into a 4x2. Primarily you need a different output shaft and matching tailshaft. Note that replacing the output shaft requires quite a bit of disassembly - you have to go at least as far as removing the output shaft clip on the front planetary. (It would only take 20 minutes more to replace the 3/4 clutch at the same time.)

Your good to go, the shop changed the output shaft and tailhousing. It's done all the time, but usually reversed (2wd to 4wd) when the harder to find 4x4 goes REAL bad and u need a core.
It took the guy all of 30min to do that, but it would be right.
