I'm planning to purchase side mirrors w/ signal lights built in for my RX300. However, it does not come with harnesses. Do I have to bring to a specialty shop in order to have this installed?

When I depress door lock all other door locks actuated except drivers side. I have to manually lock it inside or outside. What is cost to have this repaired?

I had a rebuilt transmission installed about 4 years ago. How often should I change the transmission fluid? I drive approx 110 miles per day during the work. Currently, I have 226K on car. Is there anyhting else you reccomend I should change pertaining to the transmission?

one has been showing for 4 years not sure which one but engine lite has been on that time. I cant afford to replace all the above sensors... is there one that is more critical than the others for gas mileage? Car is used just for short trips to village and church and occasional trip of 150 or so miles. Even with the little use it starts and runs perfectly. any suggestions? thanks for your help.

belt are there any other belts that i need to replace to get rid of this embarrassing noise? It sometimes makes the noise a few minutes after i start the car. it sound like its a belt issue but i don't know what to do...

car stalled out but it started ten mn later

at about 5 to 10 mph when the brakes are applied on dry pavement the abs vibrates through the pedal

a transmission shift kit fits on the valve body of the transmission with smaller passages to promote more fluid pressure

pause at initially pressing the accelerator, gas milage is poor... should be 21-22 in town and hiway now is 16

Light came on while driving.

Whenevereer I turn car on, there is a sound coming from behind center instrument console. Sounds is like a switch trying to turn on, or more like CD changer shuffling CDs. However, I removed CD unit.
