2004 Prado Overdrive problem

[DwayneArnold]

Hi 

I have 2004 diesel prado and it has decided not wanting to go into overdrive/ 4th gear for some reason Reving at 3000rpm. 
My low beams decided not to work at the same time. 
I can hear a faint squeak but not constant when driving at 100km and 3000rpm. 
not sure what it is or a fix for this problem. I checked all oils all good , I also checked the transmission oil , it is high level so wondering if this could be the problem

Hi Dwane and welcome to the forum. I noticed you also posted this query in another section of the forum. No need for that as we can all see any latest posts when we click "latest Posts" so in this instance it will become a double post.

Not knowing the service history of your vehicle, there would be a few bits of information you need to provide in order to get a more valued response.

Can I ask how you checked the transmission fluid level ?

Was it serviced recently ? (Transmission)

You could have an electrical fault too. Probably best to have a specialist take a look at it. Sometimes a connector can get corroded or dirty or even possibly vermin chewing on cables. I've had this very issue many years ago in a Hilux I had. Vermin thought to make it their own little hidey hole under the engine cover and chewed through a section of wiring harness which affected the overdrive. Toyota had to replace that section of harness and all was ok after.

So there's probably one or more things going on with your Prado and therefore gets quite difficult to pin point without some eyes on it.

Hopefully it's nothing major. Can you let us know what you find ?

All the best

Cheers mate , checked the oil with the dip stick behind and below the engine dipstick.

it was serviced but don’t think the transmission was last month before we bought it from a relative. They’ve never had this problem besides a small squeak every now again which the mechanic couldn’t pin point.

The transmission fluid needs to be checked when the fluid is hot. Not sure if you did this.

Usually, the best time to check it is after the car has been driven for some time as to reach full operating temperature. Say you arrive home from work, pop the hood with engine running, pull dip stick, wipe it, then reinsert it and remove to read.

Strange coincidence, but it is possible.

So replaced the transmission oil , cleaned out the sump and also replaced transmission filter but still hasn’t fixed the issue hmmm. Off to a transmission place tomorrow I guess unless someone can help here
