According to the maintenace book the car was last :cries: serviced at 66,000 miles at crown lexus in ontario, ca. The car was driven in so cal so i don't think it went through any heavy duty action. I went to pick up the car this morning and after about ten miles the same problem happened and I had to get towed back. I purchased the car at a used car dealership so the only warranty is through them, not Lexus. I'll keep you posted. Could the tranny be trashed after only 77k miles?
