It's a 93 1.9 5 speed.
Would this cause any damage to trans
Unlikely. Just drain it and replace with ATF.
I had to add fluid to my car on a road trip last summer, and the parts store listing specified gear oil.
However, I knew it should be ATF and bought that instead.
Many years ago I checked the transmission in a new to me 1963 Valiant and found ATF in it. I also thought some knucklehead screwed up, but it turned out that ATF was the correct lube in that three speed, non-synchro first gear transmission.
I took it apart later just because that is what I did with everything I had when I was young, and found it was made pretty much exactly like all the other three speeds that used gear oil.
So I conclude that transmissions are pretty forgiving about what lube is in them.
I was worried.
I did drain it.
Drain plug was really tight but it came out with a breakerbar
Got my new speed sensor. I found if you sand the part that slides in the case down a bit and put antisieze on it the come right out
Let us know if it works any different.
Trans seems to work good but now the power steering pump is bad
I know it's not an escort, but my '88 Camry uses Dexron III in it's 5spd trans.
Do you need a spare?
There's one near me, cheap:
$40 · 1987 Toyota Camry 5 speed transmission
That's a good deal! But it's already been swapped with an '86 Celica transmission (also Dexron III) that's doing fairly well
there are are a hundred thoughts on this topic... the atf flows better and doesn't go acidic as easily as gear oil in this application..
The ATF will have less drag on the moving parts, so will give minutely better mileage, which might be of interest to the manufacturer.
I always use Mercon in my Ford Trannys. Haven't had a problem yet.
I figure since I ran my transmission dry, filling it up with anything close to the designated fluid will make it a hundred times better.
Happily my transmission has been fine after last summer's debacle when I ran it out of fluid to the point of it popping out of gear when driving.
A couple years ago it started to pump its lube out the speedometer head, so I was in no hurry to top it up.
