Good morning.
So my Toyota corolla 2006 is jerking when u put the gear in drive. Also when i am accelerating...as it changes from gear 1 to 2, you ll feel the jerk(a kind of forward push).
I have heard the issue with my matrix before,and it was the gear mount that got broken,it was changed and the jerking stopped.
But now, the mechanic checked all the engine seat and gear mount and they are intact.
Transmission fluid is well gauged and pink.
Injector, fuel filter and plugs are fine.

However, we noticed that the bottom plate of the gear has hit ground before and slightly pressed inward.
The mechanic plan to open it and straightened it out, he said the gear might be forcefully drawing oil because of that.
He also said there's a worn up 'cup' beside the gear which he has packed.(that However didn't resolve the issue)
The jerk is just a bit exergerrated beyond the normal gear engagement you ll normally notice when you engage the gear.
From my previous experience....it shows thesame way it does with my matrix untill i changed the gear mount.
I was suprise this corolla isn't gear mount issue.

Please any plausible suggestions 🙏

Have you scanned the car to see if any code relating to transmission issues will pop up?

Did you ever change the transmission fluid and if you did, was it changed with original Toyota Type IV transmission fluid?

I’ll advise you scan the car first before doing any trial and error with a Kazeem
