Error code 63
 

I got an error code 63 on my '95 4runner, 3.0 V6 with auto trans 2WD. I've owned this Toyo for two years. It shifts just fine for the first 25 miles or more. After that it will not go into first gear unless I move the stick to "L". This just started last week. I don't think its an electrical problem because it only happens after several miles. Of course why would the solenoid "stick" once the fluids hot? I really don't want to buy a new solenoid and find out it was something else. Any ideas. This is the first time I've ever posted to a forum, be gentle.

I'm going to replace the solenoid with a airtex/wells. I didn't see any other brands except duralast. Anyone got a better brand they have used?
