Sidekick 4speed Automatic 03-72LE // Venting ATF // Capacity Question
#17
it's all normal. (all most all that heat comes from the TC, and if full of foam, it will get hot) are you pulling brick loaded trailers?

the car can't pull a 5 lb trailer., much less 10k. (its not designed to do that) ever.
this transmission will not overheat. if the engine stays at 180F.
my 2 door car weights just 2000 lbs. one of the lightest cars made (it's like a box kite with high CG, ever drive in buffeting winds?, ouch , not fun....)
this 4 speed is used on much bigger cars, even the mazda mini van. ( up to 2 times our 2door weight and more loaded)
the Aisin Seiki A40D series is run in many a Toyota. it's not rare , the only unique part is the 4wd tail shaft adapter, for Suzuki. (and custom TCM)

the transmission is tuned to run at near 180F. (engine temps... ) if fact if runs too cold it shifts wrong. (harsh)
it's engine heated, and Rad cooled. (it may run 170f with no load , on flat roads at say 60mph, id not go faster in any kite)

here is a truck with a dash board, with trans gauge it's clear where the overheat marks are, and 190 is cold.
below that its not even warm yet, (this is new cars with syn AFT, that you too can run)
see the dash here?

I'd say 250F max. and if you hit 250 back off the throttle and find out cause.
Is engine too hot.?
Gauge fibbing?
too much or too little ATF (overfilling any transmission will cause it to foam up, and it may over heating or worse, imagine just the TC full of foam.?
and how bad that will slip and make heat. and starve bearings , air does not lubricate bearings, at all. it is like running , w40 for oil, thin and useless.
never over fill any A/T.
the correct amount is 1.6qt, and add to hot full. all other numbers are for overhaul....(or TC clutch out, or valve body out. etc.)

These cars tran's don't overheat, it's not really truck at all. it's a toy car. 2000 lbs. or 2000 + 1000 load.
We never see complaints of this ever, sure engines, but not trans. The trans will overheat with engine, they are married..
IF the a/t cooler lines in the RAD flow good, all is good., for this tiny light car.

Dexron VI fluid. This is a full synthetic fluid that can take MUCH more heat than a conventional fluid. (like DEXIII day 1)

so there are like 3 or more temperatures for the A/T. where is yours.?
1; pan AFT gauge>?
2: out bound trans line to rad. (super hot)
3: return line temp. this line goes to the pan, (cool side)
4: clutch temp ? youll never do that one, but the outbound line, is close to , and will be the most hot.


no dought heat kills most things.
but 180 is normal and 195 is only 15 degrees rise. (on a typcial hot day ) (not in Alaska on a very cold day , up there they have a bypass to the cooler, if too cold)
