I figure if there's an adjustment available, it's meant to be adjusted.

|excellent reply Ken.
|
|exactly how I figure it works.
|My guess that turning the screw in is 'more'...
|it tightens the brake band a bit more.
|and obviously it has to not drag at all when not engaged ..
|then grab hard when it is.
| I figure it is only 'hope' that could help it keep going a bit more ..
|if that's what the problem is ...a worn brake band for 2nd gear.
|If it's worn beyond spec or useful life ..it's just worn out.
|
|I had the pan off and all looked pretty nice in there.
|I have driven about 200 miles since then.
|that it's intermittent seems a bit strange.
|the miles are fairly high on it ..
|so I know it's probably really due for a rebuild really.
|
|just thought I'd ask.
|thanks !
