Hi Guys,

I'm driving a 1995 Nissan Sentra S3 A/T. My problem is I'm suddenly encountering a very strong shock/jerk everytime the transmission shifts from 1st to 2nd gear, it's as if I got rear ended, but this does not happen in any other gears. The ATF was replaced last december and upon inspection it still is very clear with pinkish color, it doesn't smell burnt or anything. This happens whether I push the throttle hard or not.
Hope you guys find the time to help me troubleshoot. Also worse comes to worst how much does a tranny overhaul or surplus tranny cost?

Thanks.
