Where is the drain screw located on the 4L60E transmission?

And where would I pour the new fluid in?

Thank you for the help.

 

I am going to guess on this one (so if I am incorrect please correct me), there is no drain for the 4l60E transmission, I believe you have to drop the transmission pan, and I believe you add the transmission oil through the dipstick with the red snap cap on it.

Correct

 

Rated from 1-10, how hard is it to do?

Any tips anyone want to give me so I don't:

A) Spill over a gallon on tranny fluid everywhere

B) Damage the pan

Or should I just take it to a transmission shop?


Thanks for the help.

 

Man I like the looks of that pan. A little pricey but I might just have to have one anyway

 

I use a small hand cranked pump with a 3/8" inlet hose. Push the hose down the dipstick tube and crank 'till it won't suck any more fluid out. (If you don't have a pump then take out all pan bolts except 2 in the front, then loosen them and let the rear of the pan droop spilling the fluid into your catch pan) Then remove the pan, then the filter, clean everything up, install new filter, bolt the pan back on and fill. Check owners manual for fluid fill amount for filter change.

 

What kind of fluid do you guys recommend I use?

Mobil 1 Synthetic ATF? Dexron?

Thanks, I will be doing this tomorrow, and I appreciate the help

 

I always install a plug as I drop the pan for the first time. They sell a plug at most local parts stores that you just have to drill a hole and screw to halves together, than insert the drain plug. I then drop the pan for filter every 30k and drain just the fluid between pan drops (15k). That will keep the fluid clean since you only drop approx half the fluid out when you drop the pan. Allready in the girlfriends car. They have not put drain plugs in GM cars since the late 70's. I asked the instructor at a GM tranny school back in 1980 why no plug. He said, 1) weight savings, 2) cheaper cost, 3) they want you to change the filter not just the oil. Yea right I'll bet it was #2 all the way. I'd stick with regular DEX III if you still have warranty. Later>>>>>>>>>

 

Sorry to dig-up an old post, but how many qts. of Tranny Fluid will I need? I can't find my car manual. Thanks

 

It should be between 5-6 quarts. I have used the mobil 1 synthitic ATF, and its good to go.

 

A cheap alternative with more capicity is to buy a Silverado transmission pan. It is about 1" deeper and has a drain plug already built in. I paid around $50 for the pan, gasket and filter kit that goes with it from my local GM guy.
