Abeg make una help me ooo

I drive a 2010 Honda Accord and it recently developed an issue.When I engage the gear in reverse or drive it makes a 'kpoom' sound and the engine vibrates for a split second.When moving it takes a while for the car to pick up speed and climbing a hill is now difficult.Someone suggested I check the engine seating, which I did.The engine seating is intact.What could be the problem?
Code is p1658
Car also shakes a lot when engaged and worsens with AC on

Please Lexius how did you later solve this issue??

My car developed one fault and i wanted to check if anyone has experienced and has an idea what it could be

Honda accord 2010

Na AC compressor i go do
After the man fix am, i go carry the car
I noticed on my way it wasn’t moving well and the gear wasn’t selecting well
(Note: i had not driven it much)
And was really entering reverse and drive with force like “ gbim”(a loud thud)
So i parked to check the gear oil because i know when they remove radiator some of the oil will leak
Lon and behold the dip stick didn’t have oil on it,
I sha bought a dextron 3 oil to top it up and drove home but it didn’t stop change much
The car was revving high and no selection or change in gear
But i didn’t speed
Was just going home jejely

Next morning i took it to gear guy and he settled down and opened it and said gear is gone and that fiber is burnt but i didn’t smell anything burnt
All i could smell was hot gear oil normally
He said he will try his best that it should work. He sha bought abro cleaner, he loosened some of the solenoid on the gear and cleaned it and fixed them
And Coupled everything
Lo and behold
We took it for a test drive and it worked ok

The issue came back again on my way home when i parked to get something
I wanted to reverse and it engaged but loudly and drive same thing and gear didn’t change
I called the guy, he now said i should disconnect battery head and connect it back after 5 minutes and check
Lo and behold it stopped and it drive smoothly and selected gears appropriately
But anytime i off car and i want to start it again and i don’t disconnect battery for few seconds and plug it back
The problem comes
But if i disconnect battery
It works fine until i of the car again..

I didn’t believe the burnt gear thing
When i called the gear guy back and told him i need to disconnect battery to always reset
He said i will buy gear and that it’s gone
But i don’t seem to buy this because i took it to someone else that does gear (mechanical) (first guy was gear electrician) the person said nothing burnt
And that if gear is truly burnt, and scattered as he said , why does it work when i disconnect battery and plug back?
That it’s probably something electrical
Although i go go scan am tomorrow sha
But has anyone experienced anything of such ??
