Hilux Gearbox made of Glass?

G'day folks

I'm in the market for a decent 4wd (but not super modern). I accept going for an older vehicle comes with some risks. I used to have an old hilux for a long time and am well versed in how little repairs on an older car can stack up.

I'm currently looking at some 2004 model (sellers are calling it a KZN1) hilux 4x4s. I ran the details by my mechanic who is very into hiluxes. He now has an older style hilux (like the one I sold....) . He said the slightly newer ones of 04 I'm looking at are prone to gear box issues, said people say their gearboxes are fragile and like they're made of glass and very brittle but depends how they've been treated.

The ones I'm looking at are 300,000km or slightly less and one has already had a second hand gearbox installed, which suprised me because my old hilux I had (a petrol) had the original gearbox still going ok at 400,000km.

I guess I would expect some things, as things have become more 'modern', to have been made more sh*te as that's how everything seems to be going, but would those on the forum agree that the gearbox in this era of hiluxes was a little soft?

Anything else that I should pay particular attention to?

The sellers are all saying their cars have barely done any 4wding since new. But I wonder why the previous owners would bother getting a 4WD if they're not going to use it, then again there's plenty of people who like to have them for show!

Keen to hear some thoughts, very much appreciated!

Some gearboxes just let go when unexpected my 07 BT50 spat 2nd gear at around 215,000 from memory not heavy towing the mechanic said it was odd because 5th usually goes. But lots of things can add to one failing like inherent problems or not regularly changing the oil also used for towing heavy trailers or vans etc or larger than factory tyre size or engine power increase. Diesel engines also have more torque so more stress.
There are other 4wd brands on the market besides Toyota that might have better gearboxes so less worries.

I've had my 04 Hilux for nearly 20 years, It's done a hell of a lot of The High Country with the original gearbox. It's at 282k. The rear diff threw some teeth a few months back. Considering the amount of work it's done in the bush Im surprised it didn't happen earlier.
The front diff is within spec as a lokka has been fitted with free wheeling hubs recently.
These vehicles are popular among the young ones now ..

It's basically been Bullet proof out there and I'll keep it awhile yet because it just does what I want it to do without issues.I was still on original cv's till recently...

The last of the Japanese built hiluxs. I had a v6 auto ‘03 kzn for just over 200k kms. Most issues with those boxes are operator induced trying to tow in overdrive etc. I gave mine a fair hiding towing an 19ft boat up beaches and trailers up cape York etc and it handled it well. Just don’t swerve of the highway - they will simply fall over. On 2 wheels at 100km isn’t as fun as it sounds.

thanks Batts88, what do you reckon has a good gearbox?
Don't know of any vehicle in particular all you can do is research like you are for people's experiences and work it out from there. It also helps to pay to get a vehicle inspection when you find something you like as they can find other issues that don't stand out. I would try to avoid heavily modified vehicles not saying they all are at risk of having issues though.
Also avoid anything that has been an ex mine site vehicle as they will have lots of dust or coal dust built up under the dash which can cause electrical issues.

awesome thank you all for your contributions! Taking all your feedback on board for sure. Yes swerving off the highway on two wheels does not sound fun!

Would there be much difference in reliability etc between a 1KZ-TE and a 5L-E hilux engine? The latter also known as a LN167R?

Personally I wouldn’t be to concerned about the gear box unless you plan on a lot of towing heavy weight or long distance towing
ALL cars have good and bad points, the trick is to buy the cat that the good stuff suits what you want and then drive, maintain and replace as required for what ever the weak points are then any car can be a good vehicle for the individual
Having owned and driven a LR Discovery for well over15 years and getting close to 750,000 km with the same manufacturer without being stranded once is proof that good driving and planed maintenance is the key
