After removing the B2 Piston what method/s can you use to detect a broken B2 Band?

You should be able to push the brake band onto the brake drum and feel it grip and when you release it kind of springs back (a tiny bit) - if it slides or flops about then the band is probably broken - there isn't all that much movement sideways for these bands...

...it is a bit difficult to explain in words though...

Don't leave that there - I'll take it to bits!

Thanks. That is what I thought but it has been a long time since I pushed on mine I cannot remember what reaction I got.

I was thinking I could make a video of a good one for you - but then I remembered your dial up internet connection and thought it might not be something you'd be able to see...

As I'm dealing with this exact issue myself - I'd love to see a video on it.

Also - from where and what direction should pressure be applied to the brake band?

Thanks,

On thinking about this (and the cold horror of having to dig something out of the depths of my garage in the middle of winter) I reckon perhaps a video isn't going to be forthcoming until spring has sprung!

To help in the mean time I reckon the safest way to check for a broken B2 band is to remove the valve body as well as the piston.

Here's where the B2 is fitted on a 722.3(03)

And here's the little bugger on the 722.1(18)



722.118 Automatic transmission rebuild (Monster DIY)

In both situations the gasket between valve body and casing should be replaced. (If I remember correctly several people have reported weird **** going on with strange internal leaks when the gasket has not been renewed)

Very cool. Thanks for the photos!

You're welcome

If you get stuck and really don't want to remove the valve body I'll see what I can do later on in the year when we get some better weather.

For more pictures follow the links - and I've probably got some more on a HDD around here somewhere if they are not good.
