Top off tranny fluid

I checked the transmission fluid and noticed that it is slightly under the range for HOT (I drove about 15 miles, and checked it on a flat surface with the engine running and in gear). So I'm thinking I will top it off to get it back into the crosshatched area on the stick.

Ok, after searching the threads, I found the type of fluid to use.

Now, 2 questions.

1. Where to put the fluid into the tranny (yes, I know you can use the tranny-dipstick tube and a funnel, but is there an easier/more convenient way)?

2. How much to put in if the level is less than 1/8" from the lower edge of the HOT range? (I'm thinking about starting with a quarter of a quart and going from there).


Thanks.
 
Fill it through the dipstick tube.  If I'm not mistaken, the low to high level represents a quart.  If it's overfilled, the vent tube will take care of the excess if it gets hot enough.  Or, you could drain it from the plug, but I understand they're practically welded tight.
 
Thanks. I estimate that it'll require 1/2 a quart, but I wanted other opinions.
 
better question is...

if you think it is low...

where did it go?

Also... thought you check fluid level in park

I was thinking about that.


Well, that's why I wrote the procedure, so if it's wrong, I can be corrected. :)
 
Check it in park while hot :)

You fill through the tube.  At that amount low, if it still is, 1 pint is likely plenty.
 
Today i had my oil changed and i had asked about droping the trans pan too look at the fluid, well didn't do that as they have a machine to change out ALL the trans fluid which they did.
As the fluid is changed out (with the motor running) you can see the color of the fluid, when it all done and said the machine moved 13 Qt's of ATF out and cleaned it up.

that's a nice option but changing the filter is REALLY important as well,most vehicles don't have drain plugs for that very reason(GM wants you to drop the pan to change fluid AND filter)

curious to know how many miles you have and if you've done this at regular intervals
 
                    Was first time had the trans flushed, and have just under 47000 miles on truck.

thanks  (y)
 
easier way to add is to flip truck upside down and remove tranny cover and put it in lol I wou;d like to know were it went. If I were you I check for a leak.
 
I use the spout cap from a 1 quart gear oil bottle.  Fits right on the trans fluid bottle, works great for topping off.
 
Quick question.   I installed an aux transmission cooler thanks to info on this web site. (y)  I have been checking the trans oil per the Avy bible, hot and in park.   I put 1 quart in, but unsure how to read the level.   The hard part is after adding fluid to the dipstick tube it does not run all the way down right away.   So when I put the dipstick in I get a little running line of fluid along the one edge.   Here is the question:  When I pull the dipstick back out am I looking for the highest mark, all the way ACROSS the dipstick?  I assume so, if this is the case I am still 1/4" low after 1 quart.   Like a dummy I did not do a check prior to adding the cooler so it could have been low prior to installation.   I do not want to add too much.   Any input would be great. ??? :eek:
 
after pouring some in...

go cycle the shifter... R then D etc few times.. this will move fluid around...

Also allow what you poured into to drain into tranny and out of tube...

then you can check...

if you have some on sides of dipstick it makes it hard to know exact level of fluid..
