MAZDA BT50 2018 WENT INTO LIMP MODE TOWING UP A HILL WITH SMALL CARAVAN ATTACHED.

That catch can is going to stuff your warranty, unless it was done since the problem arose. But a friends father is having the same problem you are having, I spoke to him today, their are a few bt50's in the area with the same problem, and they are in the class action. He has had enough, but, they are fitting a new engine this week under warranty, and he is getting rid or it straight after. Another guy, locally I spoke to this week has had 2 of them , the last being a 19 model, and he has nothing but praise for his vehicles, he loves them, and has had no problems, so it might come down, to the actual guy that builds them and say's near the end of the day, "ah, that's near enough" like I said before

The catch can will not void any warranty UNLESS it can be proven it was the cause of the problem. I,ve had a catch can on my vehicle since new and there is no way a functioning catch can will cause overheating issues. The class action is saying that it is a known issue...many of the affected vehicles will not of had a catch can fitted.

OMG !! Could be after market windscreen wipers ??

Nah, they'll blame the non genuine Anderson Plug.

Maybe the unpainted schackles?

UPDATE = MAZDA AUS requested weight of caravan and car fully loaded with photos , car fully loaded , then caravan fully loaded AT A WEIGH BRIDGE .booked into local mazda dealer tomorro for at least five days and will give me a loan car, then a MAZDA tech guy will go for a one hour drive with caravan on tow and try to replicate the conditions when it went into limp mode. its going to be hard to replicate 2 hours of driving in 34 deg heat then find a long fairly steep hill in melbourne ( 15 deg ) in a one hour drive , ITS IMPOSSIBLE.

They're clutching at straws or possibly putting on a show to look like they're doing something when, probably, they don't have a clue.

They could simulate your situation on a dynamometer and it's quite likely they could model it too.

Maybe get an insurance disclosure from them and make them go up Black spur a couple of times

Did a 15 minute drive with caravan on freeway with tech expert today, said i should put into sports mode and change gears manually when towing caravan at all times, he wasnt sure about no power and engine reving high going up long,steep off-road track, could possibly be transmission slip. he will have a short 4wd in low range and give me his verdict tomorro. ps-- ANYONE ELSE CHANGE TO SPORTS AND CHANGE MANUALLY??????

All the time in ours when towing.

iana · Guru

We did a circuit around Aus, towing with a combined mass of 6400kg or more. Never once have we been in limp mode. The oil in the transmission was not burnt. But we have a scan gauge II fitted and drive according to transmission temperature. Normally drove in sports mode, and when going up or down steep inclines used the manual gears, still maintaining respectable gearbox temperatures.

I drive a Pajero that has had a lock-up kit fitted to the transmission. Before this I drove a hell of a lot of the time in sports mode to keep the transmission temperatures down. As people are towing bigger and heavier road blockers the transmissions are asked to work harder. Everyone that I now uses the sports mode , often, when towing. It is vital to have an Ultragauge or scan gauge fitted to a vehicle to be able to monitor the transmission, engine temp and intake temps when towing...you,d be amazed at just how hot your vehicle gets...ignore the dashboard gauges...they react when things are way over hot anyway....limp mode means the max temperature has been hit on the transmission and it is shutting down to prevent damage...On my vehicle that is at around 147 degrees celcius!Anyone towing more than 2500kg with their dual cab are really pushing the real boundaries of what their vehicle can tow safely and reliably. 3000-3500kg on a dual cab is bull****e.

147C is far too hot for automatic transmission fluid.

As I said...thats what the factory alarm is set at for limp mode...128 and alarm goes off as a warning.

We try to keep the temperature at 106 degrees, this can mean early morning starts and camping after 12. Speed is what I find puts the temperature up, so as the transmission gets hotter the speed comes down. We have traveled on very hot days of temps up around 40 degrees plus, sometimes you just have to stop and have a cuppa and take things easy.

Aus-Kiwi · Guru

Yep ir just let it die a little on hills ? Like a non turbo would ! Go back and drive a non turbo !! You will see what I mean ! Almost lose half the torque ! We expect to keep up with traffic with 4 or 5 cyl diesels ( small diesels ) towing 3+ ton and wander why we have durability issues ! They can ! But not keep up with traffic 100 % of the time .

Towing 2200kg my tranny sits around 75. Hills and very hot weather see 95 maximum.

128C is far too hot for automatic transmission fluid.

That is why the alarm goes off at around 128 and then limp. I think I was thinking about 147 degrees for some reason...but as has been said...that is just way too high a temp and oil would be cactus (tranny too, probably). Mate told me that 128 is the setting for alarm and limp mode for the Pajero..think I,ll do some more digging....

You have to do something about it getting so hot to start with (there has to be a cause ) - add an oil cooler, use a lower gear, off load a lot of weight , drive slower . Small Auto gearboxes have no "reserve" when expected to work hard.

Frictional heat from the gears and torque converter slippage heat will all start to multiply and add up.

Just had it verified..Alarm goes off at 147 degrees. Bloody joke. Thank goodness I have an Ultagauge to monitor the temps and a lock up kit to control the heat..

Then some say you dont need a trans cooler !

Mike196 · Senior Member

I have a 2020 Pajero (MY21) and it has a decent eternal cooler factory fitted. Just need a scangauge now.

cobberdog · Senior Member

Best place to buy and fit transmission oil cooler and gauge please, ARB or TJM?,or mechanic in melb/ airportwest area.

Mike196 · Senior Member

Most specialist Auto Trans places can supply and fit.

The more I read about today's 'beaut utes', the happier I am with my petrol guzzling GQ 4.2L efi Patrol.

SWMBO keeps nudging me to get a new Ute but I just show her threads like this & we are right for a bit.
