4R70W 2-3 shift problem

[ran260gt]

Last night I was driving and all off a sudden my car would not shift into 3rd
so I pulled over , checked trans fluid and the level was fine ,but the fluid smells alittle burnt , fluid has less the 3000 miles on it , so I start back out and at first it shifts normal ,then I come to a light , as I start it would not shift into 3rd , I have to rev it to 4k then it shifts , today I take it out to see what its doing , same thing , under normal throttle it will not shift into 3 until 4k , but if I drive with very light throttle , it seems to shift into 3rd fine , but when in 3rd it drives fine , just shifts late from a dead stop !

Also today started out from a dead stop driving down hill going 35mph and it would not shift into 3rd , stayed in 2nd and as i hit the gas it would rev like it was in neutral ?

No codes so im going to drop the pan and valve body , and look for a damaged 2-3 accumulator , if thats not it , im lost !

Any input on what it could be ! thanks

Hope its a easy fix! You said you changed the fluid 3K miles ago. Did you use Mercon V?? I heard of all kinds of tranny issues starting because of the wrong fluid. I also had the filter fall out and into the pan on my 94 GMC and that caused all kinds of shifting issues.

Thanks , but im scared , I hope its an easy fix too, and yes I change it with Mercon V every 8-10k , didnt drop the pan yet , but the Ford filter fit nice and snug when I installed it !

The direct clutch is worn. How my miles to you have on the car? Have your computer scanned for codes first, just to rule out anything electrical.

66+K , and no codes !

I had this problem while drive on the highway at normal speeds. The dealership replace the span ring. The car was under warranty and worked fine till I broke the stub shaft last year. Do a search on span ring on this site.
