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.

 

Thank you.

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:

 

thanks. Now for a rebuild I should replace everything or just the forward apply band?

 

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.
