The bands have to "brake" the clutch drums to stop them rotating. It is part of the process of changing the speed or direction of the output shaft.

So there is no "wear" issue involved, then? They just work slightly slack over time, so as long as you torque them correctly, it will be adjusted properly...Yes?
Thanks....

Yeah they do wear. They are like big drum brake shoes. The drum they grip can wear too. So they need a tighten now and again.

Careful what you're doing;

So they need a tighten now and again.

It's a bit more involved than that. Always ask for help or read your manual when adjusting bands....................

Agree with Kev -

I am touching *nothing* but the sump Gasket - everything else can wait for Blues magic touch in the future !

Err. Kev. The instructions I gave ARE from the manual.

I'm a very wary person when it comes to doing anything mechanical the first time...but it seems to me that the job of band adjustment is simply a matter of making sure you have a good, accurate torque wrench and are methodical about following the instructions to the letter.

If I'm wrong , tell me. I know that a great deal of work on autoboxes is best left to a specialist, but I think there is a danger of propagating the belief that some skills are unlearnable......

This is something I don't buy into.....you are never too old to learn....

Economics my dear chap. Why pay someone to fix something that anyone can do with simple hand tools?

As a kid I was always taking things apart to see how they worked. Took my mothers iron apart when I was 7 years old. Got it working again too. Although there were a few washers and bits I never figured out....

When I was 16 me and a lad down the street (who was 14) used to take his parents Austin 1800 automatic for drives up around Ponteland and around the country roads mooning at people we past. I looked older so I used to go into the pubs and get beer. Yes we were very naughty lads in Benwell.

We were worried the trans was getting a bit "funny" so we adjusted the bands ourselves "by feel" one sunday while his parents were at the Club.
He had seen his older brother do it on his Jag so we gave it a go.
It didn't do any harm but i can't remember if it improved it much. I think it was a little better.

The thing is not to be scared. If you have clear instructions you can't go wrong which is why I used a B&M kit to rebuild my transmission the first time. The instructions with these were the best at the time. It was easy.

I don't think that anything is a specialist job. A specialist is usually nothing more than someone who has spent many hours or years (more likely to be years) working with one type of item - whether its transmissions or tattoos - nothing is unlearnable, but many things are either very complicated or look as though they are until you start working on them. I'm more inclined to think that you just need to feel confident in being able to do the job and need to have the right tools. It's usually the tools that will hold you back, especially the expensive ones that you may only use once or twice

The only thing I don't have for rebuilding transmissions that I would like is an air line to check the operation of some of the parts before final assembly. But that will be changing soon.

A specialist will have all the pressure gauges to test a faulty trans for the source of a problem. But usually you don't need these.

I will wait for Duncan to put me right on that!

Seeing as our resident Student has graduated I was taking over and not reading all of the postings

Please accept my apologies Dave, I have given myself a dry slap!

Hanging out with Blue and seeing an array of broken/busted/melted and good boxes being stripped and built has been most enlightening and Autoboxes do not scare me anymore. It ain't voodoo anymore!
