Could it be a tranny problem or throttle sensor or solenoid?

The Overdrive will not kick out or on automatically. You have to push the button on the shifter under the interlock knob where your thumb will normally rest with your hand on the shifter. Personally on my Corolla I use it to aid slowing That is normal, not the throttle sensor. But if you stomp on the pedal it should drop a gear or even two accelerating

There is no o/d button on the shifter at least not on this car. So it has to be something else. I woul be helpful if some body would tell me more about it. Thanks Fordnut.

yeah you got the OLD Corolla- I love those, they are the best! just run and run- do you live in the mountains or somethin' steep hills? I don't understand the problem- the car is not a 4-speed- not that year- you got 3 speeds to work with- going down hill it goes too fast? but you want it to downshift going uphill? ok, just grab the shifter and slide it down into "2" when you want it to get up that mountain- not like they got a lot of power, anyway-

its a 93 97 model shouldnt all have the same tranny systems for shifters i mean. yes going down hill it feels like its in a rough gear like if i put it in 2 or 1. Going uphill does the same and when i get to a more leveled surface it stays on that rough gear if i let go of the pedal its kinds of feels like something pulls it.

The 1.8L -7A FE that you probably have is a stroked 4A FE 16 valve (before VVTi) and put out 115HP. Surely not a speedster but will get out of it's own way. May I ask what rpm it runs at at ... ooh...say.. 60mph?

Yes it does! around 55 to 60 is when all starts to get rough on drive. it changes fine all the way to 3 and it does not drop anymore gears. So its this normal?

Going down-hill yes, normal. It will not down shift it's self. Only until you stop it will go back to 1st gear
