Has anyone run a torque convertor lockup in a 100 series turbo auto and towed a 22 foot caravan ,did you get any better fuel economy ?

Looked at them from Wholesale automatics But decided just to drive in 4th all the time. Towed a 25 ft 2900kg van and got average of 17.5L per 100km so was quite happy.
Never towed in 5th as the box kept hunting up and down at the look of a slope .
Best torque revs was 2350 which was 90kph in 4th
Consumption wasnt any worse than the small distance I did in 5th and engine actually ran cooler as was lugging at that speed in top gear.

To add to this I had an oil temp on the tranny and it usually reamined around the 75deg mark except on hills Highest it ever got was 110 on a steep hill south of Adelaide Was down into 2nd near the top going over that. EGT was up over 500 as well as it was a hot day as well.

Run a torque converter lockup in my 5 speed Prado, don't use it as much as I thought I would but it is good on hills for holding in gear but it's best use is dropping the Tranny Temp which it does almost immediately. I can be in 3rd on a hill and the temperature will be at 103 C, engage the lockup and it drops down to 86 C in a few seconds.

Just be careful that it doesnt make it run at too low revs and make it lug as fuel consumption will go up with overfueling. Always found it ran best in the sweetspot and not severely under load

Save your money....tow in 4th and fuel consumption will be good, easier on transmission and more responsive. 5th should not be used for towing anything with a bit of weight in it...
