Chris Clodfelter uses Lucas Transmission Fix in 1989 BMW 325ic

My car was having trouble shifting out of first gear when cold and slipping very badly. I took it to a mechanic and and while the transmission fluid was clean, he flushed it and refilled with Lucas. I have not had any more problems shifting at any temperature. I was so impressed that I used the oil stabilizer to help quiet the valvetrain at start up. The engine is now much more quiet.
