I been getting two different readings. My first reading is when I drive for 10-15 min. I check the fluid seems low about a quart. I then go on a quick freeway run about 5-10 min and it shows full but seems a bit bubbly. Both reading are taken in park. How do you guys check your fluid to have the most accurate reading. Thanks

If you are checking with the engine running this would be a potential problem. If so, turn it off and let it sit for a minute then check?

IIRC, I believe that you are supposed to drive the car up to operating temperature, then ensure it is stopped on level ground. With the engine still running, cycle the shifter back and forwards through each position three times, then let sit in park with the engine idling for approx. 5 minutes. Do not switch off engine! Now you check the transmission oil level against the marks on the dipstick.

In summary:

1. Engine and trans at normal operating temp.
2. Test with engine idling
3. Car parked on level ground
4. Cycle shift lever through all positions 3 times
5. Let car sit idling for 5 minutes
6. Check dipstick level

really simple, engine running, up to temp after a drive of 15-20 miles,level ground, the level should be at the full mark, if it is low, there are probably gonna be bubbles, because it's aerated!!

ChasUno has it right. I've never done 3 rotations up and back, usually one. I wipe the stick clean and let it sit idling for about a minute before I shift thru the gears slowly down and back up too. But the rest is exactly how I check.

No need to shift thru the gears if you've done 15-20 miles!!

86ttop is correct. If you have driven the vehicle around for several miles and the motor is up to operating temp, there is no need to roll through the gears before checking trans fluid level. But, if you pulled the car out of the garage and warmed it up in the driveway, then you will have to roll through the gears to get the trans fluid to all the various passages before checking fluid level.

Good luck,
Fred
