2005 Pontiac Grand Prix GT 4dr Sedan (3.8L 6cyl 4A)
My Grand Prix has been taken into the shop a couple of times due to what felt like the transmission slipping, but they said they couldn't find anything wrong.. It still has the same problem after they reset the computer. But they did fix a recall that was on the car. I like the style of the car and it does have power.
Style of car..and Power
Need to figure out why transmission sounds like it jumps into gear.. And humming noise in engine.
