I can feel a hard thud/knock when hitting the gas and letting off in first gear

I can feel it around the footwell area behind the pedals. It'll even happen when it shifts from first to second gear but subsides after that. After some research I'd like to say it's at least the rear motor mount or possible the front as well. I had the transmission rebuilt last year and I asked if the mounts were ok and they said yes. But did the really inspect them? Not sure what else it could be.

I've tried visually inspecting them but you cannot see much.

Mine does that too, bump.

Although I did a 'PCM Reset Procedure' today that I found online and it seems to be shifting/down shifting smoother (from N to 1, and 1 to 2).
Is this an actual Honda reset procedure? No idea, I can't find it in the service manual anywhere, but people swear it works.

Today I realized part of what is going on. It was nice out so I turned off the A/C and guess what? It went away and is shifting perfectly with no knocking. Even the pedal feels firmer.

Sounds like a throttle position sensor issue but why would running the A/C cause that?

Sputtering in low gear

SputterIng has occurring when I'm in 1st gear on a auto trans 08 tl. I've always used 91 or 93 and just recently used sea foam to clean throttle body. I can feel the shaking from exhaust on right rear side. Is it a motor mount, fuel filter or something else. I have no idea and I need some advice from experts from azine...thank
