How do i know? 4R70W or 4R100
I would like to know an easy clean way to identify what trans i have. All this talk about what a piece of !@#$ the 4R70W is has me concerned. My truck is a 1999 4x4 sc 5.4. I have 150000 miles and change fluid on a regular basis. The truck has all the heavy goodies from the factory like trailer tow and the heavier rear diff ( which i think is the only one with the 5.4). I just want to know as i drive the @#$@ out of this truck every day and will need to budget for a trans if i have a 4r70W from the sound of what others are saying.
Thanks

If you look behind the drivers door where the recomended tire preasures and stuff are, it tells you there. Where is says "TR" and a letter underneath. The letters should be "E" or "U". "U" is the 4r70w and "E" is the 4r100. I'm not %100 on this but I have looked it up in the past. I have two rigs that have the different transmissions in them and the above coresponds with what is on mine. If you do a search here on maybe "transmission type" you should find a thread or two that verifies this. Or, someone might respond here.

Up until about 98, the 5.4 got the 4R100, after 98, the 5.4 expy got it for all 5.4, all navis have the 4R100. On the F-150, after 2000 it depends on the emissions package, the 7700 payload could still have the 4R70W. But the easiest way is as mentioned above, the door code for the 4R70W is U, the 4R100 is E, or count the pan bolts, 14 for the 4R70, 20 for the 4R100.

AODE/4R70's have 16 bolts around the pan and the E4OD/4R100's have 20

Are 4R70 transmissions Junk?
I don't think so. Of course, they aren't E4OD/4R100's but they aren't "bad" units. We rebuild these transmissions almost weekly. Properly maintained can be great transmissions. We replace the direct drum with a steel drum during a rebuild, along with other this and that's. You also have to make sure you have an adequate cooling system in place. Flush out those cooler lines
