I am getting ready to do my tranny service, can I flush it myself or does it need to be done by a shop? Or is dropping the pan and losening the VB enough?

Thanks Bob

 

I Do Not Like Loosening The Valve Body. I Do Think There Is A Better Way To Skin A Cat So This Is What "i" Do----

Buy 3-5 Gallons New Fluid
Buy Drill Pump Used For Liquid Transfer (hardware Store)
Pull Tranny Pan
Install Drain Plug--if You Want To (i Did, And It Makes Things Easy)
Pull Old Filter And Adjust Internal Band
Put On New Filter & Mabey A Pan Gasket
Install Pan
Adjust External Band
Fill Tranny With 3-4 Quarts New Fluid
Locate The Return Line Coming Off Of The Tranny Cooler In Front

Remove Return Line

Use A Hose Coupler And Attach Extended Hose To The Return Line (rubber Part) Then Attach The Drill Pump To That Which Will Be Fed From Your 3-5 Gallon Fluid Container With Fresh Fluid.

Install An Extended Hose To The Hard Part Of The Cooler (where You Took The Return Line Off) & Route It Into A Bucket--this Will Be Your Drain Of Old Fluid.

Start The Truck With Ebrake On And Shift Into Neutral (this Will Start The Fluid Moving)

Immediately Run To The Front And Start Your Drill Up Adding New Fluid To The Return Line. Do Not Go Too Fast Or Too Slow With The Pump Or You Will Get Too Much Or Too Little Fluid Being Exchanged. You Can Usually Judge How Much Needs To Be Pumped In By Looking At How Fast The Old Fluid Is Coming Out Into The Bucket.

I Use Clear Hose To Judge When The Old Fluid Is Properly Exchanged To Fresh Fluid (when The Color Going In -is The Same Color As It Is Going Out).

I Then Shut The Truck Down And Attach The Lines Back Up.

The Last Thing I Do Is Obtain The Correct Fluid Level In The Tranny And Keep An Eye On It For A Few Days.

Sorry For The Long Post But I Hope It Helps You Decide Whether You Want To Do This On Your Own Or Not. I Personally Love Saving The Money Doing It Myself. It's Just As Good As Taking It To Somebody And This Way You Know You Have All New Fluid Everywhere In The Transmission And Things Are Done Right. This Is How "i" Do Things And It Has Always Worked Good For "me". Good Luck.

 

Good post...

You can also just get a new torque converter, one which has a drain plug.

**** manufacturers... I really don't know why they don't come with one. Its not like they anticipate a fluid service or anything

I hope that DC enjoys that $0.10 they saved by not putting a plug in my converter.

Can anyone think of legitimate reason, other than cost, on why manufacturers don't put a drain plug on the TC? I guess some Benz's did not come with an oil drain... maybe they are afraid of people doing their own service?
