...civic lx? something hit the underside of the vehicle and caused transmission fluid to be leaking out. It's not much but still it's a leak. Are there any compounds or mixtures I can use to paste over the area that's leaking? welding it was recommended however that would involve taking out the entire transmission as it is housed in one aluminum casing. any help appreciated....Thanks. car is a honda civic LX 1995 1.6 engine.
