wtf !!!!! wowww....I expect a better answer. Anyway let explain to you. In Integra 1990 the speed sensor is also a small Power steering pump. This pump is also know as variable assistant power steering and its located in transmission. This kind of assembly was used by Honda in models late 80' and begining 90' in Accord, Civic and Integra. Also Legend 2G used them. For Legend model there are available a repair kit for power steering speed sensor, but so difficult to find for integra.
If anybody knows where to find this repair kit or separeted part, let me know ASAP. The whole assembly cost around $250.
