About the shift solenoid/automatic transmission. on 1996 Toyota Avalon

I have to decided what to do about my car and would like some input in what others would do. I noticed that my car has been shifting a little late. The check engine light is on and had it checked out. Said it was the shift solenoid and that is in the tranny. From what i heard. Also i am the third owner of this car. It has about 211,511 on it now. For some reason the second owner did not keep any records on it at all. I am wanting to replace the gasket, fluid and etc in the tranny. But what i am thinking and have heard is that if this has not been done before. If i go a head and do this. That it may cause the seals and etc to leak and i am looking at a big car repair bill. The fluid does not have a burned smell to it. It is a dark red. I would like some expect advice in what to do. Thanks for your help.

if the car has that many miles I wouldnt recommend you change the fluid I ve told people before not to change the fluid but they went and did it anyway and about a week later its on a tow truck with blown transmission

Thanks for your advice. So do you have say any alternatives. What is you view on alot of i guess you could say additives or some thing similar you see on shelves. That are suppose to help out. A nother question for you. Since the shift solenoid is in the valve body from what i heard and that is in the tranny. Since the car is shifting a little late. Do you think say in the short/long run. That it will affect the tranny in any way.

Had thought about that. But i am not sure if it has ever been done or not. If not and if i do it. I might be looking at a new/rebuilt tranny.

if its the lock up solenoid depending on the tranny you will either have to take the bottom pan or the side cover off

You have me thinking about some thing here. From what i was told at the toyota service department. It is in the valve body. I could be wrong here and not sure if i am. If i am and maybe you could correct me. If i take the pan off. Should i be looking at what is called the valve body. Also just your view here. If i do not have it replaced. Do you think i maybe do more harm then good. Since it is shifting a little late.

if its front wheel drive then the valve body should behind the side cover I would suggest you take it to a tranny shop and have them check it out

That would more then likely be the best thing to do.
