Transmission rough or misfire

I just rebuilt my transmission. On the transmission forum I have detailed info of my progress. The car is shaking when put into gear, under the hood it appears to be a smooth idle and it’s starts quick can misfires cause messed up shift points especially in 1st and 2nd gear. I don’t feel any slippage( as in rpms fluttering when shifting). There is hesitation even before 1st shift even starts

Off the line is when I feel the stumble the most it is hesitating could even one of wires crossed cause it to still run

Re: Transmission rough or misfire

Could be. Easiest way to find out is to pull plugs and look to see if anything seems odd. Ign wire arcing somewhere or a fouled plug. Being TBI, it's less likely to be a fuel issue like an individual injection.

Here is some pics of the plugs I’m still having problems. I smell burning metallic smell almost a caustic smell, it’s got to be running lean
