1994 toyota paseo: overdrive problem

I have a 1994 toyota paseo, with automatic transmission with overdrive. When i take it out on the highway, it takes some time to go into overdrive. I would be doing about 60 mph with the rpm up high. It takes sometime to go up to overdrive, and then the rpm would come back down low. At this time the car would be running normal at the speed of 65 mph at a low rpm. Also, at around the same time i have no heat, just cold air blowing out of the vents.The temp. gauge on the dashboard has a very low reading, once in a while the temp. will come up, then go back down to the lowest reading on the gauge. Does this problem have to do with my overdrive problem? THANK YOU, RON GERSHMAN I have an overdrive problem also. I have noticed that before when I first turned the car on I would have to wait for it to warm up due to if it did not the overdrive would stay high until it reached its temp, but lately is has gotten worse. Lately the car even though it has reached its full temp on gauge it is still not receiving the overdrive. The RPM's stay high and it comes down very fast. The overdrive light now is flashing and when I start driving is seems as though it stalls a little to pick up speed. I checked the transmission fluid which is normal but the fluid color is black. I also forgot when I press on the overdrive button on the gear shifter it does not work. the light comes on but the car does not pick up speed. Help.

I would start with replacing your tranny fluid. black is no good. your tranny should hold about 7 qts of fluid. The tranny fluid runs through your radiator to help keep it cool. If your thermostat is stuck closed your eng coolant won't circulate and the coolant will get hotter inside your radiator. thus making your tranny fluid hotter and breaking it down. After time it will turn black from getting too hot. Let your car warm up to normal operating temperture then grab your upper radiator hose. It should be very warm. If not your thermostat is stuck closed.

SOURCE: 1994 toyota paseo: overdrive problem

does it loose heat when you set still? is it full of coolent? whats the climent like were you at? is trans. low on fluid?when was the last time trans. was serviced? i know on most cars and trucks low fluid or old fluid can cause it to do what your saying, and also cold weather. some cars have a temp.sensor that won't let it shift into overdrive until car gets to a certain temp. with your temp. guage fluctuating the two could be related. has your service engine light ever come on and then went out, when it did this? if it ever has, have it scaned and see what codes show up. it might be that temp sensor i talked about. well thats the best i can do for you RON hope it helps or at least point you in the right direction to cure your problem.

What is the o/d button on top of automatic gear stick for please


Over Drive..... Generally speaking, overdrive (OD) is the highest gear in the transmission. Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway. When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [43+ mph] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. For an automatic transmission, it is almost always best to select overdrive and allow the transmission to control engagement of the overdrive. (It may be necessary to switch it off if the vehicle is being operated in a mountainous area or when towing a trailer.) With a manual transmission, overdrive should usually be selected when the average speed is above 70 km/h (approx. 43 mph).

My Paseo's overdrive does not start working until a mile down the road. It was worse during the winter and we changed the filter and fluid. But the problem is still there. It has something to do with...


Hello. My name is Toyota Ed. Please allow me to assist you.

The truth is, your Paseo is working properly.

To lessen emissions, Toyota does not allow the overdrive to engage until the engine temperature reaches 177 degrees F.

The "OD allowed" temperature is determined by the coolant temperature sensor on the engine. This sensor prevents the computer from allowing the OD to engage until the 177 degree threshold is met.The warmer the coolant is, like in the summer, the faster the 177 degree plateau is reached. In colder temps, like in winter, it takes much longer for the coolant to warm up to the desired temperature, thusly taking longer to shift into OD.

If the overdrive engaged before 177, cold-engine emissions are more abundant.

There is nothing that can be done to change the point at when the OD is permitted to shift.

So, your car is in excellent working condition. Nothing to worry about, now that you understand the basic design.

Thank you very much for choosing FixYa for assistance today. I hope that my input proves useful to you. If so, a 4-thumbs up rating form you would be greatly appreciated.

Have a great day.

According to Haynes Auto Repair Manual, section on automatic transmissions, the 1994 Towncar has the AODE transmission
Baumann Electronic Controls website

has following:
The Automatic Overdrive (AOD) transmission was introduced in 1980 as Ford's first four-speed automatic overdrive transmission.
The AOD-E transmission is essentially a beefed-up electronically-controlled version of the AOD.

How to use the overdrive on the auto.transmission.


the overdrive button on your automatic transmission is for cruising on the highway basically like having another gear for better economy careful not to use it when your not on the highway because lugging the car in overdrive when its not needed will cause higher fuel consumption other than that you should have no problems just get out on the highway and push and away you go

How to use overdrive button


Use it only on highways and you should wait until you are in 4th gear to turn it on. If used in a moutain area, it will put more strain on the transmission so make sure it is not on while going up hill.
