i know this is a CHEVY chat forum, but I need some help here. I'm very
frugal, and want to do this myself, Please help me.
Ok, I know there has to be atleast one or more master mechanics in here. I
own a 2003 Grand AM GT, and I want to change my transmission fluid and
filter, however there is no dipstick. How do I go about checking the fluid
and know how much to put back in? Couldn't I just drop the pan, then measure
how much fluid came out and put the same exact amount back in, or what?
Plus, is it also possible to drain the fluid out of the torque converter
with the trans pan off by disconnecting on of the cooler lines?
Don't be so sure, a lot of newer vehicles don't have a dip stick on the
transmission. I believe they have a filler plug similar to a differential or
a manual transmission. You fill until you've reached a specified level.
There is a small plug in the end of the right side of the transmission,
very close to the section of the transmission where the right axle
goes into it. The procedure is like this, you would drain your
fluid (remove the pan, etc), change the filter, re-install the pan,
install about 6 liters of atf, start the engine, cycle through the
gears, put it in park, remove that plug, and slowly fill until fluid
begins to come out of the plug. That's it. Oh, and if you need
to jack up the car to get at the plug, you must keep the car even,
you can't just jack up the front of it. The fill plug for these
is a red colored cap on the top of the trans right under the exhaust
crossover. So watch that you don't burn yourself.
Probably to keep the customer or a shop from inadvertantly
throwing something in the trans that shouldn't be there, or
keep the trans from being overfilled. There is also the whole
perception of "no maintenance vehicles" that the manufacturers
want people to buy into. The new Equinox vehicles don't have
any dipsticks and GM tells the owners that they never need to
change the fluid for the life of the vehicle. And I've heard that
GM is trying real hard to bring out vehicles that don't need oil
changes done for 60K kilometers. Kinda like you lease the car
for three years and then throw it away.
The fact is that you can still do the identical work to the
transmissions that you used to be able to do...it's just a bit
of a nuisance to perform the filling procedure.
The Cadillac CTS has the same type of procedure for it's
transmission, but because it's a rear wheel drive car, it's
a real pain in the ass to fill. Plus, the fill procedure involves
getting the transmission to an "exact" temp before checking.
Ridiculous....as if people are going to pay some technician
an hour to "check" their trans fluid. On an oil change, I
don't bother checking the trans fluid, as there is no way of
doing it within the time frame of the oil change. If the trans
is not leaking, it's ok. Same thing with the transmissions without
dipsticks....we do not check the levels on those during a basic
oil change anymore. The level plug is only used when doing
a service, or when a repair has been done.
so folks don't maintain the fluid, the tranny burns up, and the lot
lizards that sell their products can sell them a $25.000 new car
instead of a $1500 transmission.
Call me paranoid if you will-- but it's true, folks.
You can't really drain the convertor like that. Sounds like
you need what we refer to as a "flush". We have a machine
that hooks in line with the cooler line and exchanges all
the transmission fluid.
Exctly, however, in my opinion a true flush is with the transpan off, so
you can change the filter in the process. I want fluid out of the pan and
the torque converter, cause I dont want to contamniate the new fluid.
A '01 & '02 3.1 cars.
Pan drop and filter change is a 2 gallon refill.
Did the first one by checking then draining and measuring what was in it.
Refill and checked out OK. It's a pain to get the car level on ramps and
jack stands to run it up to temp and check the level.
2nd one got the drop, measure and refill with the amount that came out. Both
cars had tight no leak trannys.
With a 2 gal. change there can't be much left in that FWD trans. , haven't
checked the dry fill spec. but mine were clean and in good shape so I'm not
"anything you say can & will be misquoted & used against you"
We do that procedure too. You can do both the regular style
of "trans service" and also flush out the rest of the fluid. We run
12 liters of fluid thru the transmissions...that will pretty much
clean out any transmission as far as fluid capacity goes.
