Lexus Troubleshooting Questions? Ask a Lexus Expert
Hello and thanx for using just answer. May I help you. first things first sorry to hear of your problem Lexus cars are usually trouble free cars, does your car have a temperature gauge as well as the warning light? Did the gauge read high when the light came on? what as the reason the deer gave you why the transmission needed to be replaced ?
OK that's pretty vague what they told you about the transmission were the gears striped ? slipping?trans fluid discolored? if the transmission was slipping for what ever reason that could cause over heating. did your coolant go down or get discolored? Then the cooler line could have broke inside the rad and contaminated he trans fluid. So without knowing what they found in the transmission I'm just guessing. But that's my educated guess with this information. Hope this helps.
