White nissan murano 2011. transmission failing. Repair or for parts. Still looks good inside and out. A lot of new parts within the past year however transmission has been failing. Code # po456 and po442. Need to get rid of it as I already got another car. Was told by shop it could be an easy fix with a valve body or could need a complete rebuild/new transmission. Or best to use as parts. Engine is good with 162k miles. Must tow as it is failing will drive and then completely gets stuck.
