My ’07 LX470’s tranny was making a strange noise, and I could feel it slipping. I just had a complete service done to the entire rig, tranny too, ALL fluids drained and replaced, brakes, timing belts, etc, and then drove it 800 miles. The noise started and the slipping started a few days after the trip. Stopped into a tranny shop and they found that it was two quarts low! Yeah, the idiots didn’t top it off correctly, and denied responsibility, of course. Too late though, as adding 2 quarts never helped the problem. Went to a Toy dealer and they found that some burnt marks on parts, obviously from lack of sufficient fluid, which caused the slipping. A local shop they used wanted $4800.00 for a rebuild! Toyota quoted $5000.00 total for a Toyota certified remanufactured tranny installed, with a full one year warranty through any dealership. I had no choice, was stranded. They had the tranny there by noon the next day, and I was on the road the following morning. I got a 10% Mil.gov discount, and the price was less than quoted. So all said and done, $4370.00 out the door, and that was with a loaner truck, snacks, drinks, and a free t-shirt … LOL! Ok, to be fair, I asked for the t-shirt. LOL. LX was washed and vacuumed, ready to go. Now, you might say that $4370 is high, but bare in mind, it is a certified remanufactured tranny directly from the Toyota warehouse, and is fully warranted for a year. Also, they checked everything out, I mean EVERYTHING, all included in that price. You do NOT want just anybody rebuilding your tranny, or replacing it, unless of course they are LC/LX specialized, skilled, really know what theyre doing, and they give you a warranty that beats Toyota’s. And no, I have NO affiliation with Toy or Lex. My 2 cents worth. Good luck!
