Sorry I bought this
By spikey on
2004 Chevrolet Malibu LS 4dr Sedan (3.5L 6cyl 4A)
Transmission jerks when it downshifts into first, and if I press on accelerator as it's doing this, there is a bang; something loose on driver side drive train. Every bump makes terrible reverberating bangs/thuds. Cruise control kicks off because rpm is too erratic. Rough cold idle, and will stall after 10 minutes. CD player won't play CD-Rs without swooshing sounds. Interior rattles are driving me crazy, especially from passenger door pillar.
The engine itself is great. Excellent power and mileage.
Other than problems, I can't think of any improvements.
