Transmission Shudder Problems of Lexus RX

After my previous complaint of experiencing transmission shudders, the car became progressively worse. I had it taken to the local dealer, where they informed me that the transmission had failed. This car has only 136,000 miles, which is not many for the quality usually associated with the Lexus brand. They claim to have no reason for the failure, but are charging me almost $5,700 to replace it. I asked Lexus corporate to assist me with this repair, due to the known transmission issues on many Rx models, but they declined. The vehicle almost died on me in the middle of the highway on several occasions while experiencing these transmission shudders, which could have led to a bad accident. I think this is ridiculous and shows poor quality in their manufacturing.

My 1999 Rx300 awd (u140f) transmission gave 2 shudders while driving at 40 mph and then quit pulling except for 1 blk or so after restarting the engine. Took it to transmission specialist. He said planetary gears wiped out. Obtained new ones and repaired ok. 1 month later I parked and when restarted, it would not go into reverse or neutral. Had to drag out of space. Fwd ok. Drove 200 miles back to transmission shop. Planetaries again. Replaced. Ok 1 wk. Replaced whole transmission with one from highlander. Still shifts occasionally poor at 10-30 mph 2-3 shift shudder. Seems it has a maf sensor error now that may have been causing the shudder / hard shifts/failure. Car has 140 k miles. I think Toyota is hiding this simple failure causing major ($8k) failures.
