2005 LX transmission fluid q's

No. Even though you replace what you removed you still have to check the level at proper trans temp. Somewhat of a procedure but not too difficult. Details are in the "WS flush" link I posted above.

Thanks

I believe you need to check ATF level at certain temperature ranges which is more involve than running through all the gears holding each one for 10 seconds.

True, BUT a transmission reaches temp pretty quick, quicker when it's working against something, like the brakes.
From stone cold a trans will reach 150 in about 2 blocks, I assume that a person doing this job is starting with a hot transmission.
It takes about an hour for a fully warmed transmission to cool enough to be considered cold.
Since there is residual fluid in the trans that will still be hot, the new cold fluid will reach temp pretty quick.
Shifting through all the gears like I suggest not only heats the fluid it also forces the fluid through all of the passages of the trans as well as works all the different solenoids purging any air bubbles.
This is how I have always done it, this is how I was taught in class, your results may vary.

Ok Spike- Maybe you're exaggerating for a point, but seriously if your 100 series transmission is reporting 150F in two blocks you've got something seriously wrong with your transmission, sensor or your gauge. No way the the fluid gets that hot that fast at the pan unless your pulling a houseboat.

Point taken.
My numbers are being taken off of my work van which has a digital trans temp gauge, it has a larger transmission and a huge trans cooler.
I have no way of reading actual trans temp on my Cruiser.
So I stand corrected on the actual numbers.

Scanguage II with the right code allows you to pull the trans temp from the sensor in the pan. There are 2 sensors in the circuit, but as far as I know you can only pull data from the one "temp" related sensor.

FWIW, around town driving on my 05 5spd trans temps are in the low to mid 130's and it takes 20-30 min of driving to get to those temps. Highway driving in summertime low 140's. Recently towing a small light trailer with a moto, loaded truck and roof box in 100+ degree ambient temps to & from Colorado my trans temps ranged from 150-170's. Fluid was ex-changed 15k ago.
