Automatic doesn't change at higher speeds Options

[spizz]

Hi.

I've just brought a 94 GT, UK import. This is my second Celica but this is an automatic.

Anyway, I opened her up last night but in overdrive it would reach about 90mph and then it felt like it was searching for a higher gear, basically it was revving highly for a couple of seconds and then the rev's would drop, this just continued whilst I was trying to accelerate but it would go no faster than 90mph.

I tried it with the overdrive off this morning and again it accelerated up to 85mph but again didn't change. The revs were 5500 at this point.

At lower speeds it changes gear fine.

Can anyone shed any light on this for me please.

Thanks.

In most cases of an auto tranny not shifting, it's simply a bad tranny.
