Transmission going out?

Post by Juans_93_MX3 »

Everytime the car switches gears from 1st to 2nd, the car jerks.
This happens on the other gears aswell but not as hard as from 1st to 2nd. At times, you can hear a quick clunk right as it switches

Tranny was rebuilt last year, what could be the problem?

I was thinking U-Joints, cause I had the same thing happen to me for a little, and needed to change out those..and since then it's been all good
