看到东风要生产窝窝技术的14挡变速器，在Google上搜出这么一个东西：

1997 Volvo 14 speed transmission, how do I shift this truck

It's got the common "H" pattern and has a "c" upper left and "R" lower left.
Then it'a "1" upper right and "2" lower right and then it dog legs to the right, and up for "3".
It got two clickers.
A high one and a low one.
I don't know why they call it a 14 speed.
It' the common transmission behind the "Volvo" Engine.
Fluid clutch.

Thank's for any help you can provide.
I'm an old pro but this one has me stumped.
I think it's very difficult until you learn the proper procedure, then it's probably

转换成人能听懂的话就是：我开一辆1997年的沃尔沃卡车有14个挡，可是不知道怎么挂。

档位左上角写着H/C，左下角写R，然后右上写着1，1下面是2，还有一个3.

它有一个高挡位按钮一个低挡位按钮（高低档，醉了）

不知道这东西为毛就叫14挡。

这位歪果仁说了这么多应该就是指这款了，图片是13挡变速器，少了一个H?还有两个高低档拨片
