Transmission fluid level

While doing a motor oil change, i accidently removed the transmission drain plug and lost some oil. i put the plug back in, but i may have lost aboot half a quart or more. How do I check the level, and how do I a more fluid?

 

Read the sticky on top it lists how to do the drain and fill and level check.

We don't know what truck you have so can't say. year? 2WD, 4WD, V6, 4 cyl?

 

Assuming you have a V6

 

If you have a 4 cylinder, it takes Type IV ATF and the dipstick is marked with hot and cold marks. Use a funnel to add ATF through the dipstick tube.

If you have a V6, as you can see above, it is a bit more complicated. ATF is Type WS. The tricky part is removing the correct pan plug during the correct temp range. I don't use the stick-a-wire in the OBD port method. My UltraGauge displays ATF temps but I have used my IR gun on the pan and the readings are within 3 degrees from the UltaGauge.
