I just bought a 2000 Venture, Warner Bros Edition about 3 weeks ago. It has 96000 miles on it. The other day, it started acting up a little bit. Sometimes when I press on the gas just slightly (probably around 1500-2000 rpm's), the van starts to jerk. If I give it more gas, it accelerates normally, and if I let off the gas, it stops jerking. If I hold the throttle at that point, it will continue to jerk. When it does this, I noticed that the transmission shifts harder than normal. Also, Once in a while when I start it, it idles rough for a second or two. Is this a sign of the torque converter going out, or a transmission problem? The check engine light isn't on.
Thanks in advance.
