I'm the latest member of the early transmission failure club. 2002 RX300 FWD, 94,884 miles, showing code P0770 at the dealership, Shift Solenoid "E" malfunction. Of course I just dropped $1000 on timing belt/water pump replacement which was recommended at 90k miles. I also had the transmission flushed at the same time, because the shifting was getting a little rough and it was hesitating about a second when shifting into drive first thing in the morning. That was the first time the transmission was flushed.
The Lexus dealership wants $4431.17 to replace it.
The Toyota dealership wants $4209.68 to replace it.
Local AAMCO (been there 20+ years) wants between $2200 and $3100 to rebuild mine.
I've opened a case with Lexus Customer care at 800-255-3987 and am waiting to hear back from a case manager. The CSR asked what I expected, best case scenario, from Lexus. I said I expected them to live up to the Lexus name and legendary Toyota quality. I said if we had any expectation of the transmission not lasting nearly forever, my father would have never bought the car at the end of his lease, and he certainly wouldn't have sold it to me.
I'm being polite and friendly and not angry. I would be satisfied if they would split the cost and maybe throw in a 3yr/36k mile warranty. I don't think that's too much to ask. Heck, if they'd do that, I'd even consider bringing it to them for service at the regular 7500 mile intervals. Good coffee and snacks, and comfy chairs.
