shifting when engine is cold |
|
|
I thought I had this fixed when I replaced the temp sensor. Still
does the same thing but at a lower outdoor temp. Has become a problem
since the temp in Ma is dropping.
My 90 Stanza refuses to go into 3rd gear (auto trans) unless the
engine is totally up to operating temp. It used to shift into 3rd
when I got to about 50 mph on the highway. Now it stays in 2nd for
about 10 extra miles at 50 mph. Then shifts into 3rd and will shift
correctly for the rest of the day. The same issue begins the next
morning if the outside temp is around 30 degrees. The car will not
shift into 3rd until it is totally at operating temp.
I have done the plugs, dist cap, plug wires, 02 sensor, temp sensor,
even replaced the radiator because it developed a leak, rad cap, and
thermostat, checked trans fluid (it was to correct level when car was
warm). All this was completed during the summer in preparation for
the winter since the car developed the shifting issue at the end of
last winter. The car shifted correctly during the summer but now it
getting cold again and I am seeing the same non shifting into 3rd
problem.
The engine runs fine when cold and warm so I don't believe the
shifting problem is related to the engine, but I could be wrong.
I have no error codes but I still believe a sensor is the issue since
the car shifts correctly when it is warm. My only thoughts with
sensors is they are almost always bypassed when the car is cold. They
come into play when the car is at operating temp.
I need some help here, Please

When was the last time you replaced the tranny fluid?

I replaced the tranny fluid during the summer (couple of months ago)
as a precaution. I didn't want to wonder if it would be the cause
during the cold season.
Thanks for the suggestion. Dan

Are you suggesting the Overdrive shift may be the issue? I will pay
more attention to OD vs 3rd shift and see what happens tomorrow
morning.
Thanks for the suggestion. Dan

Check the temp sensor. Many newer cars will delay the overdrive (or last)
shift when cold. (In cold, my old '00 Explorer would delay the OD shift
till about 4500-5k RPM while cold.) Helps: 1) warm up quicker, 2) emissions
since the car warms up quicker. If that sensor is out of range the car may
think it's colder longer and be the cause of your shifting problem. |

It's normal for the overdrive shift (The last shift) to be delayed until the
engine is fully warmed up. Sometimes they use the trans temp to do this and
in below freezing weather this can take a while. What you are experiencing
may be normal operation for the weather you are experiencing.

Well,
This morning it was 32 degrees and in fact is now snowing and
34 degrees. Sometimes I don't really like the New England weather
with snow this early in the winter. Oh well, in a couple of weeks I
will be in Disney World in Florida.
The Stanza will not shift into OD until it is at operating
temp. I made sure of that this morning. I have changed the Rad
hoses, Rad cap, and thermostat when I replaced the radiator so they
are not the issue. I have also replaced the temp sensor going to the
Computer and the temp sensor going to the Temp gauge ( they are
different). The Chiltons said there is a temp sensor in the trans but
the dealers (2 of them) say the car doesn't have a temp sensor in the
trans.
I guess I will have to live with the car the way it is. My
daughter has become accustomed to starting the car in the winter about
5 to 10 minutes before she leaves for work. This allows it to get
warm enough to shift into OD when she gets on the express way.
Thanks for your suggestions. Dan |

Here in the Hudson Valley, all of our automatic transmission cars in |
this household have remote starters (Well, only two of the four are
automatics). |

Dan, did you change the trans filter/screen?

It won't hurt anything by just running it without OD until it gets warm |
enough to shift. They are designed for it. As I said, my Explorer would
wait forever to shift into OD and when I sold it @ 80k it still ran like a
champ! |

Most cars will do this. When I had an auto Maxima, it would not engage
overdrive until 5 - 10 minutes of warming up.
