Trip to lightning ridge and back Triton averaged 13.5ltr / 100km's towing 14.44 Expanda at 100km/h most of the trip
Sounds like the torque converter wasn't locking up. Drop it out of overdrive (5th in a Paj) and tow in the 1:1 gear (4th); that way the torque converter will stay locked up (but you're adding revs).
For as fix, have a look around for a torque converter lock up switch - try this website http://www.automatictransmission.com.au/#start and also eBay.
Also, adding an aftermarket transmission cooler can help (but doesn't address ther source of the problem...slippage and heat due to disengaged TC).
CC drop out is typical when hauling a heavy load up hill. Its not fuel efficiant to use a cc in that undulating country anyway as cc doesn't read the road; backs off down hill, doesn't gently accelerate along the flat before coming to a hoill to build momentum, instead hits the hill and widen the throttle right up.
what sort of rail mod ?
They are pretty good numbers Andrea. Towing at normal speeds or a little under the limit?
Wow not bad at allJust been for the first run with Navara and the 17-56-2,from Melbourne to bendigo got 11.9ltrs/100klm and on the return trip 11.3 per 100klm.
Thats tipping me further to the v6 Navara, i need something that has good power and the economy to match. We ran at 25+ on the last trip in the Patrol...
Are you happy with the Navara? is there anything that you would change or add?
Thanks
First long trip, Newcastle to Wangaratta 16.1OB, towed by 2010 diesel prado averaged 15.6l/100k, very strong winds so I'm not sure if that's a good indication. Will update throughout the Tasi trip.
when you of to tassie? Never been but heard it's awesome,enjoy
yer so far very happy with the navara, Very impressed with the power,tows nice very stable. Not sure if yo have seen my other post but i have put a ulimate canopy,hayman reese heavy duty towbar pedders air ride rear bags with 10psi in the rear sits 15mm higher in the rear which unload gives it a nice front to rear rake with van on the back sits level. fuel economy if it stay's like that really happy.Next trip in two weeks so will be able to give you a better idea of figures.
