GS nice to see you here. I am sure you have missed me on the TDR as my suspension won't be up until August 15th. This thread is nearly two months old, you must be bored.
I stand by my statements saying if possible ALL your transmission fluid should be changed. So far I have not figured out how to do so on the AISIN.
Maybe explain if the AISIN is perfect with partial changes WHY you added a deeper pan to allow for more trans fluid on your truck??? Not criticizing you for doing so because that's what you wanted to do.
2014, it's really simple to do a fluid exchange on the 68, why would you not do it???
