Then one day it drove to work fine and upon start up and heading home 3-4 started slipping like hell. 1-2 and reverse work fine.
I was just stating low fliud level can cause this

Sounds good

If he desides to run Dexron VI thats great, but a transmission shop is going to use DexIII because when you buy it in 55 gallon drums the price difference is alot more than 20 bucks. In my opinion DexVI will not make the transmission last longer.
