1988 Toyota Land Cruiser Pricing and Specs

If the engine power has returned since this episode, I’d be willing to suggest that what happened is that the vehicle had gone into limp-home mode. This happens when something like the transmission or engine becomes hot enough that to continue at normal pace might cause damage to the vehicle. It’s the car’s way of saving its own life, if you like. When it does, you can expect a warning light and a reduction in power, just as you experienced.

Towing a caravan up hills is a great way to get a transmission really hot, or even a turbocharged engine such as the one in your LandCruiser. If the vehicle returned to normal once it had cooled down, then you shouldn’t have any ongoing problems, but another oil change and perhaps transmission service might be a good idea as these fluids can lose their mojo once they’ve been really hot even once.

The Toyota LandCruiser is one of those vehicles that defies conventional wisdom by being super long-lived. It kind of depends on which model LandCruiser you’re talking about, but if it’s a diesel-engined version, there’s every chance that it still has lots of life left in it at 320,000km.

That presumes, of course, that it has been serviced correctly and has not been used to drag an excavator on a trailer at 110km/h every day of its life. Any vehicle with this many kilometres needs a very careful pre-purchase inspection but, being a LandCruiser, the cost of this inspection is warranted where it may not be on many other makes and models.

Torque converters have been known to seize and, if that’s the case, it could stall the engine because there’s no slip to allow the engine to idle while the car is stationary. You need to have this checked by a transmission specialist who may have seen this very thing before. Either way, the vehicle won’t be going anywhere under its own power.

Even if the gearbox itself had frozen solid, the torque converter should still allow enough slip to let the engine idle. So that’s definitely where to start the investigation.
