My Toyota Corolla 2009 (American model) shaft was replaced because of the knock/bang sound I hear when I push the gear lever from Park to reverse. The change caused gear oil leakage for some days. The seal was later changed and oil topped but the leakage became minimal. He said the rust on the new shaft cup was probably the cause, he cleaned the rust, washed with fuel and fixed it back.

Prior to and while these were going on, the gear had not been engaging to 4 and 5. After the mechanic did and serviced the valve body, the car began to rev (without a change in speed) only when I accelerate and the speedometer pointer is about to leave 40. Mechanic serviced the valve body severally (changed some solenoids), even used another car valve body but it didn't solve the revving issue ( it selected gears up to 5 on its own, however, still revvs at that point, when I accelerate myself).

We scanned the car again and it produced these codes: P2414, P0710, P2757 (P2757 code has been showing for some time though) and P2716. Eventually, the oil got burnt, 4 gear specialists we contacted said the fibre got burnt and need to be replaced. Gear Box was brought down for service, fibres and drum changed and fixed but the car still Revs at that point when I accelerate. I made sure I bought the original Toyota WS he used.

The gear specialist now suggests we replace the valve body that my gear box is very neat and can't be the cause of the problem. I'm exhausted. i had from the first day told the mechanic/gear specialist that I don't want trial work.

In summary, the issues the car has are the revving without a change in speed when I accelerate and the bang/knock sound I get when I push the gear lever from Park to reverse only.

Sorry for your experience.
Have you tried changing the back engine seat.

Honestly the idea of tampering with gearbox by mechanics scares me cus I feel they will just worsen its prognosis walai

4 persons have checked and confirmed that the Engine seats are in tact. They all said shaft is the cause and that the shaft I bought has been worked on.

Shaft causes drivability issues not high rev.

The gear components has already been compromised, buy a replacement gear, if funds are low switch to manual transmission and rest.

It is hard to come by a gear technician in Nigeria of today, sometimes sef the parts to fix the gear aren't available to a qualified techy

Update Thanks everyone for your contributions so far.

Valve body bought was fixed on Sunday and the revving stopped. However, the ride is not smooth. The car makes a knock sound when it's selecting gear. The gear specialist said I should drive the car for days that it would get smooth on its own.

I don't know how long I have to drive the car for the gear selection to get smooth, but if it doesn't after a week, I will have the gear box changed. I can't manage the car for a long time because I do interstate travel some days.
