Who changed to 90W? Not Ford....There's your answer.

Believe me. I'd get that in writing. Put the Ford recommended fluid in it
NOW!

So, you're saying you have a T-45 and a "mechanic" put 90 wt gear
oil in it??

They changed from Mercon to 90W gear oil (the tech claimed that on
manuals with over 100K this is much better and he has a few manual
Stangs). It's still a bit tight when cold but is very smooth later.

================================================

If it were me, I'd be talking to Ford first and an attorney second. It's my
understanding that those trannies were not designed to run regluar gear oil.

Someone correct me if I'm wrong, but I believe that the transmission will
need to be completely torn down and thoroughly cleaned before being filled
back up with the correct fluid.

I bought an 86 GT back in 88 that had gear oil, (I think this was around
the time Ford switched to ATF) but I replaced it with the right ATF and
it was fine for many years. (Just a back yard fluid change)

The manual says 2000 GT has a T50 D tranny. You guys are scaring me. I
didn't find anything on the web that says gear oil will damage the
T50.
Just to review, I had the original ATF swapped (with tranny flush as
well) for synthetic after 104K. It was very hard to shift when cold
after the swap, so the mechanic (at no charge), put in thicker oil
(I'm not sure if it's 90W, but he called it gear oil). The tech
claimed that all his manual cars (including a nice BMW M3) had gear
oil and it was only tight when they are cold but get very smooth
later. If I go back for the 3rd time, I'm pretty sure I'll get into a
big fight. Do they really need to flush again to put in ATF?

You probably won't find anything that filling it with WD40 will damage
anything as well What you need to look for is some sort of
verification that the 90W is acceptable.

I remember way back people would fill the mustang T5s (and maybe T45s)
with the GM syncromesh (think that's what it was called) fluid.
Purchased right from the GM dealer and was the GM recommended lubricant
for the same transmissions in their cars as I recall.

That's correct according to what I've been told.

Ok, I'm not touching that, I'd be glad to tell you what I would have
done instead, but that's water under the bridge. If it were me I would
make 1000% sure it had ATF in it.
