Getting ready to drop the transmission pan

[wood_e]

Hello all,

I am getting ready to drop the pan on my ATX. The fluid in the system has about 40,000 miles on it, and it's probably nasty. Now I know that I should drain out the torque converter in order to get most of the fluid out, but I figure changing some of the fluid is better than none.

Yes I searched, but some threads don't link properly anymore thanks to the new bulliten board software.

I got 6 quarts of Mobil 1 synthetic ATF. I will be getting a trans gasket & filter pretty soon.

My main concern is adding the new fluid to the pan. I read that the pan takes 6 quarts. Here's what I'm thinking:

1) Loosen all of the bolts in sequence and let a lot of the fluid drain that way.
2) Remove the pain once most of the fluid stops dripping
3) Clean the pan out & the magnet
4) Remove the old trans filter & install the new one
5) Remove traces of the old trans gasket and install the new gasket
6) Tighten the pan
7) Add the 6 quarts in the fill tube (where the dipstick is)

Sound like a good plan?

Yes, that sounds like a good plan. However, is the fluid in their already synthetic? If it is that sounds fine, if not I wouldn't mix conventional ATF with synthetic. I would either flush it all out with synthetic, or change half of it with conventional.

IMHO, if it has that many miles on it I would be changing all of it, that is a lot to put on tranny fluid.

Paul, Thanks for the link

Doug, I had the trans flushed at 89k and a synthetic fluid put in. I think I'll just change all of it

FWIW I don't know of any synthetic oil or ATX fluid that is not fully compatible with regular dino products.

I thought it was always a bad idea to mix synthetic with conventional.... Is that just an old myth?

All the synthetic stuff I use says on the bottle fully compatible with conventional petroleum products.

I mix synthetic with normal ATF all the time.

all synthetic is compatible with conventional petrol fluids.
but if mixed you should use manufactures recommended
drain interval, not extended drain, most atx should have
20k drain interval with conventional fluid, quality synthetic
will last 2/3x longer

After a couple of changes it will be switch to syn by then I would think.
