longer milleage panther, Transmission flush & fluid change

[fastblackmerc]

I will go to Pep Boys to buy the Tranny cooler I yesterday buy two qts of Castrol MerconV, the transmission pan I will buy increase to two qts more but I will not touch the existing oil to avoid become malfunctioning (shudder & slip) but I'll change the tranny filter. once again many thanks to CTRLRAVEN, MASSACRE, SC CHEESEHEAD, JIMMYXR7, FASTBLACKMERC, A_D_A_M, RFOVERLORD, for you contributions and help I will keep updated all you about the results in the thread of my adopted Panther. :racebanana:

You do know that when you swap pans you'll lose all the fluid in the pan?

Buy more fluid and replace all that comes out when you swap the pan.

You have that backwards...NOT changing the fluid will eventually cause the dreaded torque converter clutch shudder.

If you're installing a new higher-capacity pan, it should have a drain plug, so you can do periodic drain & fills much more easily. A normal drain & fill takes just under 4 quarts, so with your new pan it should be 6.

Actually, stryker is correct on this ^^^^^^

In high mileage Panther transmissions, if the fluid is not changed on a regular basis (like his with unknown service history), it can actually make the car slip/shudder worse if the fluid is changed. It's the darndest thing. That is why he is concerned about it and doesn't want to disturb the trans fluid too much.

[RF Overlord]

That's only *potentially* true if the fluid is badly oxidized and contaminated, and even then is more anecdotal than fact. People just assume that the fluid change caused the failure since it was the most recent thing done, when in reality the transmission failed due to abuse/neglect and would have done so even if the fluid were not changed.

I changed my fluid the night before going to Louisville, pretty much in the dark. I could not get the new filter to seat properly. I finally crawled out, got a flashlight and saw why: The round gasket on the old filter did not drop out with the old filter, it stayed in place. Crawled out, got needle nose pliers, pulled the old gasket out, slapped the new filter in, bolted up the pan (reused old gasket), poured in about 3-4 quarts of new fluid, good to go. Also, I cleaned the pan with brakklean as recommended by a 'member' here. Shined the crap out of it.

Here is the cooler with kit I buy to modify, I was expected were more bigger but the other models was smaller than this. next part I have in schedule to buy is the extended capacity transmission pan with drain, I speak with Dennis reinhart and he give a good price, other parts to get is the tranny filter and a few qts of Mercon V, I found a Ford house parts were they sale the Motrocraft MerconV, I check the color and smell of the existing oil and the color is not brown and don't smell to burned, either way I only will replace 4 qts plus two when I installed the new pan will be 6 qts.

Justbob did it for me. I could not get at it. Plus, I could not see as I am blind without my glasses.

Unknown service record...........

I'd replace all the fluids to start from a known point.

The bucket method:

1. Get enough Mercron V fluid to replace it all.
2. Get a funnel for the tranny dipstick tube.
3. Get a 5 gallon bucket.
4. Disconnect the line from the tranny to the cooler.
5. Place the line in a bucket.
6. Run the car, the fluid will pump ot.
7. While the fluid is pumping out you need to add fluid thru the dipstick tube so the tranny doesn't run dry.
8. When all the fluid is exchanged, stop the car.
9. Reconnect the cooler line.
10. Top off the tranny fluid.

Since you can damage the tranny by running it dry, I'd find a shop that has a machine that can change the fluid.

BTW.... Only use the type of fluid recommended in the owners manual. Marauders use ONLY Mercron V fluid.

Regarding Step 4, I am seeing 2 Cooler Lines that look like they go from the transmission to the Cooler, which 1 do I take off? Or does 1 go the Cooler and the other goes to the Radiator?
