a bolt came out from torque converter
 

Hi

I found a loosen bolt hanging at the bottom grill of torq conv! The bolt is about M5x15 with still some red colored Loctite on thread. Where exactly did the bolt came from? Do I have to fix this? The car is 380 SE -85, 208tkm. I tried service-cd with no result.

I was searching the vac modulator when I found this. There is a annoying clunk in trans between 2-1 downshift. I don´t understand why shifts go hard when trans gets warm. Also harsh D, R engagement jumps the car. When cold all is fine.

I appreciate your help.
