It's on a 96 4.6 bird having issues with the 1-2 and 2-3 shifts. Not sure of the exact symptoms as of yet I'll update this more as I get the rest of the info. Auto trans isn't my thing, hence I drive a manual. Just trying to help out a friend, input would be great. Thanks guy's.

The more details, the better. Check the fluid. Level? Color? Smell? Also check the common problems/troubleshooting pages of Jerry's Thesis for some info as well.

My first guess is it's low on fluid...

Ok, hesitation shifting into second, the shift is between 2,800 & 3,200 rpm's. I have not yet noticed any patern with the issue. It's completely random as far as I can tell.

Okay so now the trans is done, looking for a trans that I can swap into it with little modification. I already suggested a 5spd swap and got shot down. I've heard a little about the 4r75w,can I swap one into a 96 4.6 bird with little modification.

Aside from having to do the normal 99+ 4R70W modifications, you need to have a chip or Xcal to change the OSS count in the tune, which needs to be done by a tuner. Absolutely no way around this.

So if I can't do a tune, then just stick with the trans that should be in there or is there a direct swap upgrade of sorts.

Yeah dude just throw random parts at it until it works! To hell with testing the resistance on them, or ensuring they are operating correctly!

Because a stock 96 4r70w was a TOTAL POS when it was brand new.
A TOTAL POS?

Perhaps, some people say the same thing about the 4R70W in my '94 Bird.

I've kept it going for 19 years with just a little TLC. I suppose if I beat the crap out of it, it would not hold up.

I beg to differ. Mine has held up just fine. I've given it plenty of abuse in the 80,000 miles that I have been operating it. The only thing I've had to change was my 1-2 accumulator and spring. Everything else has held up just fine. It has almost 160,000 miles on it with no signs of failure in sight.

I could destroy yours in an afternoon without exceeding Redline - You can't kill mine doing that.
