Hello again, I need some help or advise with my 04' Grand Prix GTP. When I pull out onto the road or back out of my driveway and put it in drive the RPM's jump way up and it kinda jumps alittle. If I let off the gas and then re-apply just alittle pressure on the gas it then goes fine. I was told it was the Tranny going. I was told by others, "not to flush tranny fluid, just leave it if it is light brown, I will make it worse by changing it" and I was also told to "just change out the fluid and filter, that will solve my problems", all that brings me here today. Need some help please, Thanks.
