Going by trannie temps the torque converter only locks up in OD , OD off temps get way up there but as soon as it slips into OD the temp needle drops like a rock .
Will only use for towing and engine braking and maybe small inclines , thanks again ET that gear just before it hits OD is definitely the best gear for towing on mine and now I can lock it not only cooler temps but should reduce fuel consumption from 24 litres per 100 .
Chubba , fuel economy is secondary to heat I agree and found on my last trip to Birdsville if I could get to OD the temps were lower and fuel economy was the best under 20 litres per hundred .
