I have a service van. 2006 Chevy Express 2500...3/4 ton with 350 6.0 gas Tranny is a 4L80 with 147,600 miles. Has the towing package.
Now with all that given here whats happening. Its an intermittent problem. I can drive around town for a while then leave a light/spot sign. Now when it shifts it's feels like i gotta shift kit (through all the gears). Then i park and shut it off for five minutes (give or take a few). Now it shifts fine. Untill it wants to repeats its self.
I had the fluid (Dexron-VI) and filter changed also added sea foam for tranny. drove it 5 miles, problem returned. Still intermittent...
Thanks, Jeff
