1996 Corolla Auto Transmission problem

This is not "normal". At this point it could be electronic (bad
gorund, Bad sensor) pay attention to how long you have to drive and
then let sit (exactly). Then take it to the dealer or a trans repair
facility and say you have to drive it for x amount of time and let it
sit for x amount of time to get it to do this and allow them a
reasonalbe time to try a duplicate what you are finding this will make
it easier to diagnose.

The transmission has a thermal sensor located inside the pan,bolted to the valve body.This particular trans is the A245E model with the 1.8 ltr. engine.The thermal sensor does prevent 4th gear from engaging until the trans fluid temperature has reached a certain minimum temperature,then it allows 4th gear engagement.That particular car was available with that engine and trans from '93-'02

2005 Toyota Corolla with same type problem...now resolved quikcly.
Went to South Coast Toyota and they covered my car under WARRANTY.
Turned out to be a "Computer, Engine Con" sensor of some type.
Without warranty you'd be looking at about $ 830.49!

This is perfectly normal my car does it also. Read the owners manual and
it will also say it is normal. This isnt something new to OD trans
either. My father 87 Toyota Van even does it. It is to allow the engine
to warm up properly and to keep emissions down.

I have a 1996 Toyota Corolla with 4 speed auto overdrive transmission.

This is absolutely normal. The electronically controlled transmission
computer will not allow the transmission to shift into overdrive until the
engine is warmed.

Just one question, how do you know if your auto tranny is in overdrive or
not? I have 2 cars(auto) with overdrive, but I don't see any differences
while driving. BTW, both cars are pretty new.(96)

The impression I got from this message was the individual was driving
the car parking it letting it sit for a while then driving it again
and experiencing the problem. It was stated that it happens in cold
or warm weather. If the customer is driving the vehicle letting it
sit (2hrs on a 75 degree day) and then experiencing the problem it is
not normal, it wouldn't cool off that fast. On start up (first thing
in the morning) it should not go to OD (read below, person is not
complaining about this). I told the individual to pay attention to
how long he was having to drive and how long he(or she) was having to
let the vehicle sit. Then take it to the dealer or trans repair
facility. There is the possibility this one is new enough to not have
the thermostat cut out but I belive that it does (the newer one's just
cut Lock-up). Ask jumping bean if he(or she) is noticing the problem
in the morning when he first starts the car that would tell us for
sure if it has the thermostat switch.

Normal condition. The ECT ecu watches for an input from a water temp
sensor to signal the trans valve body to allow the shift to
overdrive. Done for emission and driveability concerns.

JumpngBean < < Absolutely normal. Tranny will not shift into overdrive until coolant
temperature switch lets it.

Most automatic OD transmissions have a temperature sensor to prevent OD
lockup until the transmission reaches a certain operating temperature.
This usually takes a mile or so unless it is really cold. It is normal
behavior. Don't worry about it.

Bob (my opinion)

The dealer is being straight with you, if it was allowed to go into OD,
while the engine isnt fully warmed, there would be more emissions, that
is why its designed this way, relax and enjoy the ride (((ooops, thats
Nissans line)))
