If internal screen is clean, do not change. It only stops trees and boulders. Gasket is reuseable if not damaged. Change FT-145 external trans filter behind right side front bumper. Replace 7 to 8 qts of Mercon SP. Have a beer or two.

 

thanks 69cj

i couldn't find filter. i was looking in wrong place......

everything ok now

 

All 100% correct except one thing... My book calls for 4 beers and a roast beef sandwich!

 

oz my type of guy!

 

+rep that one

 

ive changed my trans fluid at 25,000-30,000 mile intervals.
i drain the pan and changed the external filter.
at 100,000 miles i pulled the pan and changed the internal screen.
The pan was clean very very little wear material on the magnet.
the screen was clean and i thought what a waste of 25.00 to change it.
i Bought a new gasket for the pan and thought what a waste of 20.00.
but iam happy it appears to be in fine shape.

if and when it does crape out ill yank it do clutches and steels and throw in a new pump.I hope this happens in the nice warm months and years from now

 

4. add new fluid.


But seriously - is it worth even doing it if you don't flush the TC? You are leaving more than half the original dirty fluid.

its better than not changing it.and if you do this regularly its fine.

 

my local dealer wants $169.00 to do a flush.
i checked on cost of filter and oil.

filter cost $37.56

oil cost $ 5.50x8=$44.00

total cost for material $86.56 plus tax.

filter cost seems a little high.
i need to find a cheaper filter.

The dealer flush is going to use about 20 quarts.
$5.50x20=$110

I know you are set on doing it your own way, but check this out just FYI.

I was going to post that link, guess I don't need to now.

I installed a Dieselsite tranny filter and M-H tranny pan at the same time that I did the flush. I also installed the valves on the DS filter so that I can just shift valve lineup to flush old fluid as I add new. I will not drop the pan again, with two filters and regular flushes I doubt anything will be on the screen.

 

There is a very good procedure on the site to do a complete DIY flush but I cannot find it right now. I have done the procedure twice and it boils down to this.

1. Get the tranny to operating temperature. This reduces the tranny fluid viscosity so it will drain easier and suspends any particulates during the drianing process. Remove the drain plug and drain the pan. I let mine drain for about 30 minutes. While it is draining get another 10 quart drain pan, fill with 9 quarts of water and mark the pan at that level. Dump water out and dry pan being careful not to remove the 9 quart mark.

2. Install the drain plug and fill the tranny with 10 quarts of fluid.

3. Locate the external tranny fluid filter up behind the passenger side bumper. Do not change the filter yet. The two lines that go forward from the filter housing has a solid line that goes into the bottom of the radiator and the other line has a 1/2" hose connecting it to the transmission cooler.

4. Place the marked drain pan under the hose connection. Suggest using rubber gloves when removing the hose. Remove the spring clamp and pull the hose off the hard line. Be careful as hot fluid will run out. Get a 2 ft section of rubber hose, slip that onto the hard line and let it dangle into the drain pan.

5. Have someone start the truck and let it run until the fluid level reaches the 9 quart mark in the drain pan. You are now flushing the torque converter. This should take approximately a minute. Turn the engine off, put the hose back on the hard line and replace the spring clamp.

6. Now change the external tranny filter. The reason to change it now vice before you started is there is no sense in pumping all that old dirty torque converter fluid through a new filter.

7. Pour 6 quarts of new tranny fluid into the transmission. Approximately 17 quarts is needed for a complete fluid change.

8. Start the truck and shift through the gears a couple of times.

9. Shut the engine off and check the tranny fluid level. Add fluid as required. Suggest fill to the cold level and drive. Add any extra fluid as needed.

You need to get a TorqShift to at least 170F. There is an internal thermostat that opens at 165F. If the thermostat is not open 90% of the output from the torque converter goes back into the trans and only 10% goes to the cooler lines. It also helps to have the new fluid heated to keep the thermostat from closing while you're doing this.
