Toyota Repair Problems? Ask a Mechanic for Answers ASAP
Thank you for using Just Answer for your needs. Have you had the Transmission serviced recently?
Yes, about 1 month ago I had it refilled with 9 quarts of Transmission Fluid.
Good. The P0773 code is for Shift Solenoid E which is the torque convertor. How many miles are on this Avalon?
There are 244,000 miles on my Toyota. I know it's a lot but they're all highway miles and I'm anal about keeping the car maintained to include oil changes, transmission fluid/filter changes, and everything else.
What happens here and what causes this code is that the torque convertor wears out. What happens is that the cars computer when it activates the Torque Convertor (w/ Shift solenoid E) it looks to the crankshaft sensor to see that it is engaged. With the torque convertor working there should be a 1 to 1 rotation because they are locked, When the torque convertor fails, it does see the 1 to 1 because it is slipping and sets the P0773 code.
It sounds serious and expensive. Could it dump me if I don't fix it right away?
Somebody may tell you to just replace the Torque convertor but you will have to pull out the transmission to do so and remember that the transmission still has 244,000 miles on it. I would say to watch it till the light comes on again. If it does then just drive it till it really quites and then put a transmission in it.
Could it dump me if I don't fix it right away? Not likely.
Thanks for your advice. I didn't expect the car to last forever. I WILL replace the transmission if necessary because the engine still runs perfect and it doesn't burn a drop of oil.
Good idea. These are very good cars.
Okay, I'm very satisfied with your response. Thanks...I'm signing off!
