transmission

A re-manufactured transmission is the best option, then a rebuilt or a used transmission. It depends on how much you want to spend and how long you want to keep the car. I would be wary of rebuilding unless the shop is very knowledgeable in rebuilding this type of transmission. A used transmission is OK, but you don't know how it was driven or maintained, so it can fail as well. A re-manufactured transmission, if done correctly, will have been completely dissembled and all the internal parts tested and wear items replaced (seals/gaskets/clutch packs etc.). Call the Lexus Dealer to see if they have these available through their re-manufactured parts program.
