Default Auto Transmission Downshift Issue

4-cylinder
1993
159,000 miles

I've recently started experiencing a transmission shifting problem. It
happens mostly as I try to accelerate from a stopped position. When I
accelerate, it's like the transmission is sticking. It takes some effort
before the car will get started to drive smoothly, like it's not even in
first gear but half of a gear. Once I get going, everything seems to be
fine, but as I'm driving if I'm below about 40 mph, it feels like the car
shifts from 2nd gear back into 1st gear then out again, giving a quick jerk
as it does this. Once I'm driving for a while a little closer to 40mph, I
don't have the problem again until I have to accelerate from a full stop. I
don't have this problem if I'm doing highway driving. Only when I'm street
driving. It's also not a problem if I'm stopped facing downward on a hill
when I accelerate from a full stop. It started yesterday. My car was
idling pretty low and wouldn't start the first time that I turned the
ignition. So the second time that turned it, I revved up the car to about
5000rpm, so that it would catch. I've had to do this before, usually I
would go to about 4000rpm. I was wondering if that extra bit of revving is
what got the transmission acting funky.

Has anyone else experienced this problem with the transmission feeling like
it's sticking at lower speeds?

Thanks in advance,

Lorraine

To start with, you are describing governor and valve body failures.
People who don't get their transmission fluid changed as recommeded
(every 30k miles or less) get problems like you have outlined. Pick
a transmission shop and make an appointment before the matter gets
serious. As is, sounds like a gummed valve body.

Thanks a lot for the advice. I bought the car used, and I'm pretty sure
that I had all the fluids changed after I bought it. I've driven it about
7,000 miles, give or take a few hundred miles, but I will definitely go get
the transmission fluid changed immediately. Should I ask them to check for
a gummed valve body while they're changing the transmission fluid, or do
they do that automatically?

Thanks again,
Lorraine

To inspect the valve body, the transmission oil pan must be removed
and the valve body removed after that. This is not a job for anyone
but a dealership or mainstream automatic transmission shop.

So that I'm not put into my grave when they tell me the cost, do you know
approximately how much something like that runs? I know that a transmission
flush shouldn't cost that much, but it can run into money when they start
removing parts.

Thanks,
Lorraine

Varies a lot depending one WHO and WHERE. You could always play
dumb. Call a dealer and ask the Service Writer what it would cost to
clean the valve body in your transmission. When he chokes, tell him
your husband told you to ask this question. ;-)

Default Re: Auto Transmission Downshift Issue

Is the fluid level correct?
Check with the parking brake full on, level surface, enine running,
fluid hot after moving through all the A/T stick positions ending in
Neutral not park.

Is the fluid the correct type? See owners manual possibly Dexron III

Have them drop the pan, clean the magnets, clean or replace the
filter(sceen).

I would NOT have them drop the valve body as they won't know where to
look for a sticky valve anyway.

If this does't work a transmission flush may help.

Good Luck

Default Re: Auto Transmission Downshift Issue (UPDATE)

Thanks Philip and Marvin for all the help. I called the dealer to find out
the prices for everything that you recommended. When I got to the point of
asking about cleaning the valve body, he asked me what was wrong with the
car. I told him, and he recommended that I have the transmission flush. He
said that they would do that first and see what happens from there. So,
they did the transmission flush and drained and refilled the differential.
Everything is running smoothly again. Yaaaaaaaaaaay!!!

Thanks again,
