Congrats on the new purchase. I just bought one in FEb 2008. For answers to some of the questions, go to www.lexls.com. It gives tutorials on many things dealing with the ls400, specifically the 1991 ls400. He has a tutorial on the power antenna and the LCD.

I wouldn't drop the pan just to change the filter, but if you do plan on checking the solenoids, then, it might not be a bad idea to change it. I replaced my transmission filter when my car had something like 250k miles, and the filter still looked like new.Hinge wiring tutorial: http://www.lexls.com/tutorials/lighting/bulbout.html -Blake I just bought a '91 ls400 2 months, excpet I paid 2500 for mine with 190k miles. I might be wrong but I think that tapping noise is the valves. They probably need to be adjusted. It was more like a ticking rather than a tapping.
