That's because they don't use the plastic plug with the 4R100 (no "a") transmission.

Casey-

I thought the "A" was in the designation, thanks for clearing that up. 4r100 transmission then. I had been wondering about that plug and had asked here and on the Expy forum why it wasn't there. This is this first time I have heard about Ford not using it. I had found one in all my Ford trucks (starting with a '79). Just made me curious not to see it. Thanks again for the info.

well i opened up my 90 truck aod and gues what i found. a 5 inch curly metal shaving. i have no idea what it came off of. anyway it came from under the pan.actually it was partly in the pan and half way through a hole that goes to the drums. when my motor had bad blowby i went ahead and pulled the tranny because when i was cruising about 45 it would jerk a lot and when i got to a faster speed it went away. i guess it was in OD at that speed and i was thinking it was just the torque convertor. i was told it could be just that. it shifted fine and did not slip. even the fluid that was still in it today smelled good and was not burned. it has been out of the truck for about 2 years and i now desperatly need it in my tbird. it still is very clean inside. has anybody ever experience this.

I drain my pan/converter every 10k miles and use AAMCO synthetic blend MerconV fluid. I get almost 12 quarts when I do these two,and disconnect the lines at the tranny and blow the cooler out too.The 4R70W holds 13.9 quarts and I can get 13 back in mine.For $6.00 plus tax you can get a B&M drain plug at Autozone and install it in your pan.I also added 4 more magnets to my pan.BTW,Opera,my pan is never dirty; just the typical fuzz on the magnets. I use 409 and water to clean it then micro fiber towels to dry it.Oh,I have 95k miles on my truck.

Come on guys. I want to hear from someone with an A4LD, 4R55E or 5R55E that the pan has never been dropped in 80K or more.

What is your procedure for getting all of that fluid out? I am interested in the most "full" refill as possible, not just a dilution of the original fluids.
Thanks!

The majority of the fluid is in the torque converter. If you have a drain plug on the converter that's the best place to start. There is also 1 1/2 - 2 quarts in the cooling lines. Disconnect the cooling lines. Most of the fluid will come out with gravity. You can use some low pressure air to coax out the rest. Then drop the pan and clean it thoroughly.

Using that method, you should be able to get almost all of the fluid out.

Personally I drive the truck first to get everything lubed. Then I use the tranny pump and clear tubing on the return cooling line to pump out the cooling lines. However, I DO NOT RECOMMEND THIS METHOD for anyone else.
