Upgrade your gas hog turbo 350 or turbo 400 with this heavy duty 4L80E overdrive Chevy transmission. It is a 1999 model so it will also work for your LS engines.
I was told to shifted perfect when it was parked. It only has 125k miles on it.
It is a two-wheel drive and in a 1999 Chevy Express van. You will need to remove it. I cannot because I'm disabled
