Greetings gurus. Pls recently my car (toyota camry pencil light automatic) broke down and refused to move. On putting it on drive or reverse, it makes a clanking sound. my mechanic said it was the gearbox, which I changed immediately. But after changing the gearbox, I have noticed the car refuses to accelerate beyond 80km /hr. I was told to clean d gearbox filter which I have done bt no improvement. Wat could be the problem? Ur advice really needed.

Try to isolate the issue btw engine and transmission. Put the gear at neutral and try to see if you can rev the car to almost 6000 .

BOLAUWA:

Thanks a lot gurus. I have revved the car in park position, and I almost hit 6000 rpm. I think the issue is from the transmission,as a friend also suggested. The engine is working really well. More contributions are welcome

DrWellbeing:
Try to check the fuel pump also have you changed the gear and engine oil. If it didn't change then let me know. it happened to my oen camry pencil just of a recent and when 8 changed the engine and gear oil and fuel pump,there's a change.

Here is my observation from your post:
1. You have a car, one it broke down and stopped moving. When put in reverse or drive it would make a sound but won't move.
2. This made you replace the transmission and it started moving but won't go beyond 80kmph.
3. You then changed the transmission oil and filter in the new gearbox but there was no improvement.

Since the car started moving after gearbox replacement it is safe to assume the old gearbox got spoilt. (Were there any signs it was dying such as jerking or delay while changing gears?).
I will assume the replacement is a used/ Tokunbo and two things are involved it is either not a perfect fit for the engine or faulty and dying out as well.
So I think you still need to replace your transmission if that's the case.

AutoElectNG:
Not a perfect analogy, but will serve nonetheless

Your situation is akin to someone whose brain has commanded him to walk but his two legs have been tired together and so despite the command to work, nothing happens and nothing will happen, or his legs are partially free but tied to each other with a chain thereby allowing movement but restricting movement (maximum speed of 80km/hr)


Brain = engine

Legs = Transmission

Replace Transmission,

The current replacement transmission is faulty. I would not drive around in a transmission that cannot utilize the full range of engine power, only capable of doing 80km/hr!

Don't even risk traveling to a faraway part of the same town with your ride in its current form.

You would be stranded in no time!

Listen to the voice of wisdom above from the 8th and 12th posters

OP, before you dole out heavy cash for the replacement transmission, check your fuel supply.

I had a similar issue with a car not accelerating beyond 80km/hr. After replacing the fuel pump and filter the problem stopped.

It may be your fuel pump is shot, if so you are lucky just replace it. If that's not the case you can keep the new fuel pump and filter as spare cos you will need it eventually.


Before you replace that transmission, let your mechanic inspect for frayed cables and loose connections (I'm no mech but I know the importance). You may need to scan the ECU to be sure engine and transmission are communicating fine.

Summary: Check fuel system before attacking the transmission
