I need new motormounts .
Can someone tell me how much I should pay . (or link me to a cheap site)
Should I replace them all or just the 2 breaking ? (Front and Back right)
How much should installation cost ?

Also could that effect the transmission in anyway ?

 

replace them all for piece of mind. since you're still young replace them at your high schools auto shop.

try here for starters www.acuraoemparts.com

then try AcuraZine's black market and see if any body is parting out.

Sounds like your car is a lemon...sorry man.
