Toyota Land Cruiser Prado Gearbox & Transmission Problems
Toyota Land Cruiser: vibrating in top gear
Toyota Australia spokesman, Steve Coughlan replies: “From our records, Brighton Toyota has reported a very light vibration at speed consistent with when the torque convertor lock-up clutch engages. To fully understand the issue we will arrange for one of our Technical Field Managers to contact Mr Jeffrey and assess the vehicle. A member of the team will contact him to set up a meeting”.
Prado transmission cooler
It doesn't. It's probably good insurance to fit a cooler when you're towing its maximum rated load for extended periods. But you also need to consider the sort of roads you are using and your driving style. If you're on highways and not going off-road, and you change down manually when you want to climb a hill you probably don't need it.
Toyota Prado 2010: Overheating
Your experience is not uncommon. We had a number of reports from Hilux owners in the year of so after the ute was launched, but we thought the reprogramming of the computer had fixed the issue. Perhaps it hasn't. Talk to your Toyota dealer, and also get the advice of an auto transmission expert about fitting an external oil cooler. If you plan to travel over hilly terrain on your next trip it would be a good idea to fit an extra cooler.
Toyota Prado: Transmission fluid replacement
I would have the transmission serviced, particularly as you obviously do a lot of towing as relatively heavy loads. And like you I would expect the bonnet struts could be re-gassed if they are a problem. Dealers normally go for the most efficient option for them and replacing them with new components out of their parts department is much faster and cheaper than sending the struts out for re-gassing and waiting for them to come back to be refitted. That all takes time and costs the dealer time, money and efficiency in his workshop. And don't expect the dealer to use aftermarket parts when he can make more money out of selling you some nice, shiny, new factory parts.
Toyota Prado 2010: Gear change issue
The dealer is incompetent, and lazy. Contact Toyota’s customer assistance people and report your experience, with the car, and with the dealer, as they need to be hauled over the coals. There is something wrong with your car and, you’re right, it needs to be fixed. If the dealer and Toyota say it can’t be fixed, which I seriously doubt they will, park it on the dealer’s forecourt and ask for your money back.
Auto transmission never serviced
The gearbox is sealed in production and it's not meant to be serviced for "life", but what "life" means is anybody's guess. Oil is the lifeblood of an auto transmission and Andrew of AW Automatics is of the old school, which advocates changing the oil every 20,000 km, particularly if the car is being used for towing. On that basis you would be well advised to have it changed.
Prado transmission cooler
Both suggestions are good ones, particularly if you do a lot of towing. The external cooler will keep the temperatures under control and regular fluid changes will ensure you always have fresh fluid in the transmission.
Mitsubishi Triton: Will it overheat when towing like the Toyota Hilux and Prado?
There is nothing to suggest there is a problem with the Triton, but it’s worth checking the owner’s manual to familiarize yourself with any recommendations Mitsubishi makes about towing with the Triton. That way you will minimize the risks of having a problem.
Message from 'Smithy'
We have passed a number of these reports on to Toyota for their response and last week we received this comment from a Toyota spokesman: "Toyota acknowledges owners comments regarding the ATM light illuminating when towing heavy loads. We are currently investigating the issue. However, we wish to advise, the ATM light only indicates high oil temperature. Owners who experience this condition should follow the 'Owners Manual' instruction, as well as ensuring airflow to the radiator is not blocked."
Message from Smithy
We have passed some on to Toyota for their attention and response, and they have come back to us asking for the details of relevant owners and the dealers they have consulted so their Technical Services Department can deal directly with them in an effort to resolve their complaints. Specifically they would like to contact readers Jim Rogers of Boronia in Victoria and Mick Ryan of Niddrie, also in Victoria. If those two readers contact us at carsguide.com.au, quoting this announcement we will pass their details on to Toyota.
