Hi all, recently I replaced the trans solenoid on my sisters 2000 sebring and it seemed fine but now the "service" light has come on and she got the p1776 and p0700 fault codes. Could this be just a tcm problem (doing the quick-learn at a dealer)? Or are there any other things that could be causing this problem. Any help will be greatly appreciated. Thank you.

 

The P0700 code tells you that there is a transmission error code. The P1776 code is probably what it's referring to. That code says that the solenoid pack has a problem. Maybe the unit you put in there has gone bad. You might consider sending it back to wherever you got it ans asking for a good one.
I have replaced solenoid packs on two of my vehicles without bothering with the "quick-learn" procedure and have encountered no problems to date.
