4L60-E/auto trans fluid check.....procedure

[T.M.]

Aloha,
Some good info if your going to do this yourself.Like never remove the FILL plug when the car is OFF.

4L60-E AUTOMATIC TRANSAXLE FLUID CHECKING PROCEDURE
1.Start the engine and allow the engine to idle until the transmission fluid normal operating temperature has been reached.
2.Depress the brake pedal and move the shift lever through the gear ranges, pausing a few seconds in each range. Return the shift lever to the PARK range.
3.Raise the vehicle on a hoist. The vehicle must be level, with the engine running and the shift lever in the PARK range. CAUTION: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.

4.Remove the transmission plug. IMPORTANT: The transmission fluid may darken with normal use and does not always indicate contamination or oxidation.
5.Check the fluid level. The fluid level should be even with the bottom of the threaded plug hole.
Add DEXRON III automatic transmission fluid in increments of 0.5 L until the fluid drains from the plug hole.

EDIT.. CHECK TRANNY FLUID IN THE 80* - 122* range

I am checking mine tomorrow or monday,i figured i should post the info since it's not like the other vette autos..
I'm suprised no one askes where the dipstick is..

I was also looking at how much torque the auto can handle and still live a normal life..I can't be certain,but i think i read it was 425 to 450 lb lbs.I wonder if c4/c5 spec knows about how much it can handle.

HI there,
Factory torque capacity of a 4L60-E is about 450 ft lbs.
A critical part of this procedure is NOT there, you must check the fluid when the temperature of the fluid is between 80-122 degrees F.
If you do NOT check the fluid near this temperature, the check will be inaccurate.
Allthebest, c4c5

Hawaii-5-lo, Make sure you use the good jack stands, not the ones from the picture you posted in another thread.

Hum,hey C4/C5,
Step one says "allow engine to idle until tranny reaches operating temperature".So i'm assuming your saying that temperature is to high?
I have to catch it before it gets over 122*?
Thanks for your advise,i want an accurate check.

I hear ya,this time the whole car has to be up like that,level.That was just a one time deal that i took a picture of,that it would be a good,"how not to lift the car".

Hi there,
Definately check before 122, otherwise thermal expansion will make the fluid level higher than you should have it when checking. This makes for an inaccurate fluid check.

Hi, i want to check the auto trans. fluid level on my 2002 C5. The only plug that i can see is located on the oil pan (driver side). Is that the correct plug to do the check????? or there are any other plug that i can not see???

Thanks for any help!!!!!!!
