What are symptoms of a failing or worn/gummed up solenoid packs? Or common ones should I say. Anything in particular? ex:delayed/hesitant upshifts, shuddering, etc. I think this would be a good thread to start so people that believe their solenoid pack may be the culprit of their tranny problems can come and read about common problems and issues with them when they are failing or gummy on the inside. Any suggestions or thoughts are much appreciated.
