2005 SE Bonnie with shudder on 1-2 shift with light throttle
I am noticing a slight shudder on the 1-2 shift when accelerating under light throttle. I have found there was a service bulletin from GM that the clutch pack for that shift is to be replaced if a customer comes in with that complaint. The car has 175,000 easy highway miles put on by a traveling sales man. I don't know the service history, but the rest of the car is spotless, and purrrs like a kitty.
So...first off I will do a tranny fluid and filter change during the next oil change.
Any suggestions on a tranny fluid that might help with this condition? Thinking Valvoline Maxlife for cars with 75,000+ miles.
Also thinking of adding some Lubegard Red. This is a highly respected auto tranny additive...and I have used it before.
Is it possible to just adjust the clutchpack? How?
Any other ideas?
