CEL - P0770 issue

[jasonf]

So when I bought my 4runner a month and a half ago, it had a CEL with the P0770 code for the shift solenoid "e". I replaced the solenoids/tranny fluid last weekend. It's been driving/shifting fine, but then yesterday the CEL came back on. I had the code checked at NAPA after work today and it's showing P0770 again.

Any thoughts or suggestions?
