My 2001 3.8 auto after a hour and a half duing 85 to 95 mph . after stop at light it didnt down shift basically going neutral for 4 5 seconds, after cooling overnight its back to normal, any ideas of what it is. Temp was ok,on engine,fluid is ok to touch smell,not burnt.Ilive in venezuela and have had my 3.8 with no cats dual,predator, up to 123 by gps, i think i could have gone faster but lacked *****.

 

When is the last time it had a full flush and trans filter change?
What do you have your shift points and pressure and firmness set to?

 

Well to be sincere never, at 57000 miles guess I will do that and follow from there thanks for the lead

 

I forgot , i have the 95 tune on the predator and have not changed this tune at all any sugestionas?
