There is an automatic transmission specialist in Bayswater Victoria called Wholesale Automatics that specialise in everything you need and need to know as I spoke to them just recently about the exact same thing for my 100 Series Turbo Diesel and they are fitting a tranny temp gauge to mine in the CORRECT position next week for about $500 but I don't need the cooler as Toyota original is super big and good enough as that's the one they use if someone wants an upgrade. In relation to the overdrive extra he will explain what's what.Hope this helps,
Safe travels

Having trouble making sense ? They said you don't need a trans cooler . Yet your paying good money for a temp gauge ? The smaller trucks have lighter trans etc Work a lot harder .. Depending on model ?some have trans coolers as std . Some have had issues with the coolant type where engine coolant can mix with ATF . Destroying auto .
You'd do better spending your money (if auto).
on a Converter lockup sw. ($475) from them.
then buy a cylindrical Transm cooler from net. ($95ish.)
Tapped into oil line along chassis rail.
Not a radiator. Stones etc don't give leaks.
DO two jobs with one fell swoop then.
If wanting temp readings.
get a (forget the name??/. Please people) mk 2.
it'll give all readings for you ECU and fix bad readings too.
Around $200
If you have overheated your transm anytime.
DOn't get an oil change. That only drops some of the oil.
Leaves 80% of burnt oil still in there.
Get an oil "Flush". or do it yourself. Easy enuff.
I have an auto GQ 91 with TD42 and turbo. I installed two trans coolers in front of main radiaotors - a small one for use in winter, and a big 30 bar one (with fan) for summer and big hill towing. The small one is permanently inline - the big one switches in/out with a solenoid valve. I mounted the temp gauge on the feed out to the transmission from coolers, but my auto guy suggested I also have one on the feed in so I can be sure of actual trans temps under extreme towing duress.
I also had my auto guy do a valve body beef up/modification to increase pressures, lift fluid thruput and give better shift/clutch action for towing.
Cost was $525 which included new filter, radiator flush and fluid replacement. Drive in drive out. I saved about $1000 vs getting the Wholesale Automatic Transmissions valve body bought and installed.
Since then the auto runs at a higher temp than it used to, which is actually good for it. If the temp is too low it destroys the trans, same as if its too high. Mine was running under 50 degrees from the coolers - now it runs about 60 or so. Seems the sweet spot is 90-110 degrees before cooling. Hence my need for a temp gauge that is straight off the trans before cooling.
Anyway it isn't summer yet. lets see how it goes.
good luck with it

Last year i blew my transmission up using 5th gear (overdrive) the auto transmission specialist that fitted my new transmission told me never never tow in overdrive it puts to much strain on your transmission and it over heats . i have since purchased a scan gauge and that monitors your transmission temperature and a host of other things you now can purchase the Australian version it's called E.T.S gauge both work very well easy to fit they connect to your ECU cable under the dash just plug in worth their weight in gold no more guessing,and best of all they work.
I second and confirm the Scangauge or similar is definatly the way to go, you will need the mark 2 which can read TFT as well as may other reading. I mainly monitor water temperature as well as TFT. It will confirm your engine coolant and Transmittion fluid temperature in real time. Note that your best gear towing is the one which is direct through 1to1 ratio not an overdrive gear. This is likely to be 4th gear. With the load of your van I would think 90kph is plenty and should not too many revs.
It might be worth checking you weights as a 3.2 T van on a Range is up-there! But thats another topic!!
