so just had my trans rebuilt. an A4, between 2-3 shifting if i am lightly accelerating it kinda pops into gear, its not a smooth firm shift like the other gears. If I accel moderate to hard it shifts smooth and firm like the rest of the gears. also if i come to a stop and then slowly accel through 1-2 shift and then get off the gas,.. as i am coasting and it shifts from 2-3 its is a loud clunk, maybe it is the stepdown back to first gear , not sure.....but why would it do this? also when I put it in R or D sometimes it makes a clunky hook up noise, and when i put it in D the car wants to lurch forward for a second as it engages....anyone have this as well??? help thanks!
