transmission fluid change

I need to change the fluid and filter in my 1976 corvette.

I called the local stealership and by the time they are done with
materials, fluid,
labour, and taxes, it is around $350. They wanted over $80 for a
filter and gasket!
Corvette Central - $12.95 or so...

I did some research on the web, and it is pretty straightforward from
what I see, aside
from the torque converter. Drilling a hole in the torque converter is
not advised. The best way (aside from using a special flushing
machine) appears to be:

1- remove tranny cover and replace gasket and filter, clean it all up
and replace
2- top up fluid
3- remove one end of tranny coolant hose and put it into a bucket
4- start car, run thru gears on tranny, and drain out approx 1 quart
5- shut off car, refill transmission

repeat steps 4- 5 until the fluid coming out is the same colour as
what you are pouring
in.

In terms of the fluid, mine takes Dextron III. Apparently higher
numbers are all
compatible with the lower ones. ie I could use Dextron V. Best not to
mix though. You
get added benefits with the improvements in the newer mixtures if you
upgrade. And
more by going to a synthetic.

Now - before I proceed, I got this off the web and I am no expert. So
does anyone have
anything to add to this? Things I should not do? Errors or mis-
understandings I may
have in this?

TIA.

I always thought just dropping the fluid out of the pan was good
enough. Is the fluid burnt? I'd be a bit worried running the tranny
when it's that low on fluid even for a few seconds. I'd spend the
$80-100 to get the whole system flushed if it's burnt otherwise I'd
just drop whats in the pan and refill with the new gasket & filter.

Fluid is not burned, but old. More like 200+ extra to get it done....
If it were 80-100 to get it done I'd go for it, but they get too
greedy and try to gouge too much so they lose my business.
I just swapped out shocks, rear spring, new rad support, and rad
myself for the same reason. I'd also pressure wash the pan and paint
it etc, while I was doing it as well.

A local independent will do the work, flush the tranny and system with
his state of the art equipment, for less than $150.

Is the flush necessary ---in most cases no, but if properly done it
normally doesnt hurt anything and in some cases of problems it can
work wonders.

You can change the fluid and filters yourself for a fraction of the above.

Do you have tranny problems, or just want to service the tranny?

if you're going to try a DIY flush I would actually clean the pan first,
reinstall with the OLD filter and gasket, flush, then put the new filter
and gasket on. Flushing might put more gunk in the filter, why not get
it squeaky clean. you will lose a little more fluid that way tho

I agree, Nate, but if you are capable of dropping the pan and changing the
fluid and filter, do you really need a flush (normally)?

IMO, flushes are not normally needed, but SOMETIMES they are.

Well, seeing as most people don't bother to change it every 50K like
you're supposed to, I'm just ASSuming he needs a flush.

That sounds like an option. I do not have to have it perfectly leak
free just to circulate the fluid from the converter.....

You can't see it from there, but I'm patting myself on the back for not
poasting something like "who the hell buys a Corvette with an automatic,
anyway?"

Oops...

(seriously, I'm just giving you a hard time. But I know how you can
never have to flush the transmission again...)

The only tranny problem I have is that when the weather is quite cold,
it will hesitate a bit before it actually takes off. Once going or
once warm it is fine. The fluid has not been changed in a long while
so I am catching up on some long overdue maintenance. I suspect a good
cleaning, new filter and some good fluid will make it as good as
gold.

Cold weather means that the fluid is more viscous than usual, or that the
line pressure...to some degree controlled by the pump, is not enough to
get the tranny working as it should.

A worn pump, or other things, can cause the line pressure to be
insufficient
to cause the slushbox to shift and hold.


Do the simple things first.. Replace the filter and change the fluid. If you
get no relief, go deeper.

And, you may well have to go deeper in this case.

And in others it can screw a tranny up so much it's time to go to
Cottman's,...

The other thing (although more of an issue for Chrysler trannies) is to
make sure they use the right stuff! Chrysler trannies take ATF+3 or +4,
they use "generic tranny fluid with 'friction modifiers'". Uh-Uh! My
Chrysler tranny worked perfect, I wasn't about to mess that up!

1976 may well be old enough that the torque converter -does- have a
drain plug.

Doubtful. Years ago, before most tranny shops put in rebuilt torque
converters when they rebuilt the tranny, they would flush the torque
converters out with a special machine. On a GM torque converter, you
would actually drill into the torque converter, tap the hole with some
threads and put in a plug before the torque converter flush was done.
If this has been done, that would be why it would have a drain plug.
Most GM products gave up on the plug long before 1976. A lot of RWD
Ford cars had a drain plug until the mid-90s, but not GM.

If this car were mine, I'd put in the "formerly called Dexron III"
generic fluid from Wal-Mart, along with a new filter. A flush would
work, too if the right flush machine was used.
