I have an 2004 350z automatic. My transmission has been recently giving me hard shift intermittently especially in the morning when either using the shifttronic or when just having it on D. I have done a transmission service and cleaned the filter. I've checked for codes (using Consult from Nissan) and there were no codes stored. I checked for a software update on the TCM but it was already updated. Has anyone else experienced this?

 

As before, take it to someone who knows what they're doing
