I purchased my 94 LeSabre brand new. It has always been garage kept and adult driven. Despite my providing exceptionally good maintenance to this car, my transmission cooler lines failed three different occasions. Yes, I understand that stuff "Made in China" is garbage; however, these replacement tranny cooler lines were and are the only option available - which stinks!
