how to change automatic transmission fluid and filter

tools needed:
8mm socket with ratchet and at least a 3"extension
torque wrench for the 8mm socket that measures inch pounds (inlbs)
7/16" box end wrench
small rubber mallet
flat head screw driver
pliers
right angle pick
10 qt oil drain pan
long neck funnel.. i found a 12" funnel works best
shop rags
parts cleaner-- i prefer brake parts cleaner.. 1 can will do

fluid type and capacity:

dextron 6 or equivalent

total transmission capacity is 13 quarts
pan removal and filter change approximately 7 quarts

our transmissions are equipped with a reusable rubber gasket. i recommend reusing this unless its damaged. your replacement filter should come with a replacement gasket.

step 1:
lift and secure the vehicle whether its on a hoist type lift or drive on ramps. if your using drive on ramps you will also need a floor jack and a set of jack stands to check fluid level but ill come back to this in the checking fluid section.

step 2:
using the 8mm socket and ratchet remove all but 4 bolts securing transmission pan to transmission. i marked the 4 i leave tight in the picture below

step 3:
grab your drain pan and break loose the remaining bolts but do not loosen them yet. on the drivers side of the pan where you have the oblong section protruding towards the front, loosen the 2 bolts about 1/4" to let the fluid start draining from that section of the pan. you may have to loosen the other bolts a turn and strike the pan with the rubber mallet to break it free from the transmission. once the fluid slows to a slow dripping push the pan against the transmission and remove the remaining bolts. with one motion slowly lower and tip the pan away from you to pour the remaining fluid into your drain pan. pull the drain pan under the transmission to catch any dripping.

step 4:
clean and inspect the oil pan gasket. check for cracks , rips, or denting that may cause a leak. with the cleaner spray the sludge from the oil pan allowing the fluid to run into your drain pan. wipe off any access from the gasket seat on the pan set it off to the side and let the cleaner dry.

step 5:
with both hands grab the filter firmly and pull strait down. DO NOT WIGGLE SIDE TO SIDE because you could break off the filter neck and this will turn into a pain in the butt. once the filter comes out take the right angle pick and pull out the filter seal. this make take some time and patience just be careful not to gouge the filter housing with the pick. once the seal is out make sure the new filter matches the one your taking out just because parts people do mess up sometimes. after you make sure you got the right parts put the new filter seal on the tip of your finger lube with transmission fluid and push it into the filter neck mounting hole. once thats in all the way push the new transmission filter into the seal by placing your palm directly under the filter neck and push strait up. again without wiggling. once the filter seats into the seal make sure its sitting in the same position the old filter was in before you took it out just to make sure everything seated all the way. below is a hand drawn picture of the pan ,filter and seal

step 6:
with a rag wipe off oil pan mounting surface on transmission and make sure theres no gasket fragments on the mounting surface. check for gouging and nicks. if everythings ok place the gasket onto the oil pan and reinstall onto transmission. start all 12 transmission pan bolts before tightening any. theres no torque pattern to follow but i always snug a bolt and then snug the opposing bolt to make sure it sits flush for torquing. torque all oil pan bolts to 124 inch pounds


adding and checking fluid level
step 7:
the vehicle must be level in order to have the correct fluid level in the transmission.. if you are using drive on ramps to change your filter/fluid you will need to raise the rear of the car with a jack and support it with jackstands. try to get it close to level as possible but be safe, make sure the ramps are on solid ground and the jackstands are locked equally and on solid ground. before going under the car gently rock it to make sure it is securley raised. the easiest way to raise the car from the rear is to place the jack under the center of the axle beam .. this is tricky but possible , if theres any possibility to use a hoist type lift i highly reccomend using it

from the top of the engine/transmission look between the fuse box and valve cover, on top of the transmission theres a fluid fill cap seen in the 2 pictures below,wipe off area around the cap and remove the cap, you may need the pliers to break it free. install long funnel into hole and climb back under the car

with your 7/16 wrench take out the fluid level plug (seen below) and set aside where your not going to loose it

add transmission fluid until fluid runs from the bolt hole. start the engine and allow the transmission reach normal operating temperature (at least 104 degrees f) apply brake and shift through ranges from park to "l" and back to park pausing for a few seconds inbetween shifts. leave engine running and add fluid by half ( 1/2 ) quart increments untill fluid starts running from hole. allow fluid to stop dripping from hole then install the bolt you have removed and tighten to 9 ftlbs.. this is a plug only and just needs to be snug. turn off engine, remove funnel and install fill cap.. job done

Awesome, I will be using this. Was a little more cobalt specific than the one I was going to use.

So being level and at operating temp doesnt matter much when draining?

not for draining the fluid but for the refill and checking it needs to be warm and level

What would you say the risks of this are? In other words, is there anything youd recommend watching out for? Is there a chance the new fluid could free up some stuck nastiness and cause a clog elsewhere?

just dont break off the filter neck and torque everything...ive never heard of a problem with changing the fluid and filter, and if theres anything thick enough to do damage your transmission its allready junk.. unles you drop dirt or somethin down the fluid fill hole. and i do not reccomend any fluid additives like cleaners or flushes
