Thanks for the help. I drove it today a little more & it stopped the highway jerk. But when I'm driving in the city it was like jerking & clunking (it does't pull me forward like a trans slip, but it feels like the engine & trans lifts up & down)after each gear change & when I let off the accelerator too fast. It does it intermittenly, like I drove for like 2 hours in the city & the trans shifted great. Like I said, I don't think it's the TCC because I am averaging 24.5mpg in mostly city driving & 32 on the highway, but I could be wrong. I am going to run the codes tomorrow. I am thinking that it the mounts, because when it's Idling in Park, you can hear a rattling sounds, & when i'm driving I feel the car shaking a little & there is vibration in the steering wheel. I know it's a old car & I know I'm asking alot of question, but I just need is this a major problem
