2015 MQ Triton tiptronic - can't use manual when towing!?

Unread post by Pud3000 » January 1st, 2017, 8:33 pm

Hi guys, I have a mate that has a 15 MQ Triton, auto box with tiptronic.

When towing his van, the gearbox wont let him use the tiptronic, so he can't hold in in gear and has to ride the brakes downhill.

Transmission temp is getting warm, but is not over heating. So it locks out manual mode on it.

The dealer has fitted a larger cooler but it hasn't helped.
When full the van is about 2.4 tonne, the ute is rated for 3.1 towing capacity, and has full electronic brakes fitted and working as they should.

Has anyone else had this or a similar thing happen that might be able to shed some light on the situation?

Any info would be awesome.

It's a 2.4 diesel, too

In my experience with those (which admittedly is not massive, but still includes a 'reasonable amount' of time & kms towing on & off road, a fair bit of it even while sitting in the 'instructor's seat!) the only time that usually happens is when the auto box IS overheating, or at least getting up to such a temp that the control unit starts seeking ways to help keep the auto box from self destructing; or there is something else so stressfull going on that it's trying to save the auto box/torque converter!! :eek:

So could it be that it really IS getting too hot or stressed (IIRC anything much over 100-110 Deg C could be an issue; over 120 IS too hot!) or maybe he's got a faulty sensor or something similar causing a dodgy reading &/or reaction? Best bet might be to talk to someone like Wholesale Automatics - their 'Ask Orto' Line is pretty good for that sort of thing, & they usually know the best local bods to get whatever you need sorting done properly too, no matter where in Aust you may be! :thumb:
