v*****a 发帖数: 1332 | 1 搞了一个新玩具。。。
92年的buick roadmaster estate wagon,
V8,自动档。
机油,trans油都还okay。
打火有时候有点吃力,总体来说还好。
新电池。
情况如下
挂P挡,踩油门,没问题,rpm,声音都好;
把屁股悬空,后轮架空,踩油门,rpm好,声音好,轮子飞转,速度一直显示到90mph;
上路挂D挡,不踩油门能走,重踩油门的话,能听到“钪”的一声(金属声),然后全
车失去动力,发动机不熄火,rpm掉到1K,踩油门感觉动力不传送。需要松开油门,轻
踩油门,感觉又能传动力。但是不能猛踩,或者爬坡。
简而言之,这个破车只能不踩油门(实际是很轻的踩)。速度只能到25mph的样子。
但是有时候又不会失去动力,(用国内网站的话说,V8发出低沉的嘶吼。。。)轻松上
50mph。
我的问题是
1,那“钪”的一声是哪里?
2,什么问题?trans?后桥?传动轴?
3,要花多少钱修啊,DIY容易不?
拜谢 | e***u 发帖数: 319 | | m***z 发帖数: 311 | | v*****a 发帖数: 1332 | 4 今天又测了一下。。。
好像好多了,开了5个迈左右,速度上到了60mph。。。
其他的都还好,只要轻踩油门(基本算吊着开),没啥问题,爬坡都行;
重踩(其实不算重),就出现老问题:突然失去动力,rpm从3k掉1k,有时候伴有“钪
”的一声金属响。同时感觉发动机有点要憋熄火的感觉(应该是v8太狠了,还依旧能缓
过来)。
各位高人再给看看问题是什么? | P*B 发帖数: 944 | 5 problem with 1st/2nd gear clutch/actuator/gears
Pressing gas, triggered the trany to shift to a lower gear | v*****a 发帖数: 1332 | 6 我说的重踩,不是地板油那种,降档加速那样的猛踩。
就是稍微想加点速,微微一踩,就丢失动力了。
有高人指点,说有可能是differencial的问题
------------------------------------------------
里面一侧的positraction的clutch坏了,
你慢慢加速没事,重踩油门一侧clutch打滑,traction control
马上关掉功率输出,动力就掉了。

| c**********e 发帖数: 694 | 7 Well, look at my ID, I once owned a 1995 chevy caprice, which is the same b-
body sedan as the buick roadmaster.
My suggestion is, get a 1994-1996 roadmaster wagon, several reasons for that,
(1)you will get LT1 engine, which can be safely and easily modded to get
over 300 HP, 350 ft.lb. It can pull fairly quick and gas mileage is way
better than pre-1994 models.
(2) for wagons, you get plenty room, you can use the third row seat or
fold the seat to get more cargo space. So you get some utility for this gas
eater.
(3) Lastly, pay close attention to trany, due to the large low end torque, the tranny doesn't hold very well. Put some budget aside for rebuilt the tranny correctly. | v*****a 发帖数: 1332 | 8 前辈阿
我也知道LT1比L05好。不过不是难找么。。。
主要看到了别克那一身的假木头皮,我就决定要了,不管动力如何。。我就喜欢这样的
长相,反正也是玩具,先玩入门级别的,以后再升级。。。

that,
