x2 on talking to Dave.
But I have heard great things about the Sonnax Sure Cure Kit too.
*edit* it looks like Dave uses Sonnax parts, but offers more complete kits. Definitely just start with him.

I have uploaded a video of the problem.
That's not good! Sounds like a broken "forward apply band", or "first gear apply band". repair means a total rebuild.
Here's a write-up on the symptom from Dave at Triple Edge Performance: 4T65E No Movement D and 3 ranges only
I applaud you for having the guts to take on the rebuild yourself
Here's a great video on the teardown:

There's several versions of rebuild kits, depending on what you need. Since the forward band is one of the last pieces to come out I would definitely do a full rebuild. I would give Dave with Triple edge Performance a call, explain what you have, any upgrades you might want to do, and he will tell you what you need without ripping you off with overkill.
