2005 Mustang jerks shifting from 1st to 2nd gear
Hello. Im looking for some help. My Mustang has a BBK CAI and a Throttle Body Spacer. It was shifting like a dream before today. Now it is shifting roughly and it's killing me. As I accelerate slowly, the car jerks hard as it shifts from 1st to second gear around 20 mph. This problem has manifested after I used motormedic engine flush and changed the oil. When attempting to drain the oil, I accidentally removed the wrong bolt. It was about 10 inches to the left of the oil drain plug. It was on the tail side of the oil pan. I put it back in and tightened it relative to how tight it was when I removed it. I'm not sure if that is what caused the problem.

The 5r55s is a fickle one.
FTSeg - As Movielover40 and JimC pointed out, since it sounds like you drained some fluid out of your transmission, you need to have it filled back to the proper level. The 5r55s is very finicky about the correct fluid level and it takes some knowledge and skill to fill it correctly. If you over fill it you'll end up with leaks and potential damage to internal components. If you under fill it you end up with shifting problems (like what you are experiencing) and potential damage to internal components.
