2013 Ford Focus. DCT transmission was acting fine until I disconnected the battery to install a lightbar. Now clutches seem to slip leaving a stop and shifting, specially under a load. Was very noticeable, right away. Did my car forget how to work? Heard they are very adaptive, but it's been a few weeks now, with marginal improvement. Still under warranty. Should I get the dealer to make sure it's software is up to date? Also, my advice is to marry someone who can also drive manual transmissions, if you do yourself. Thanks for the help.

take it in, see what they say. And just drive it if they aren't changing any software, those can often take a long time to reset. Plus I believe there is a class action lawsuit against ford for that model for tranny problems
