A couple of quick questions:
1. When you have a transmission go out, it's a good idea to have the 'trans cooler' portion of the radiator flushed, or, get the radiator replaced?
2. Adding a friction modifier to transmissions that have a lockup torque convertor?
Any thoughts?
Neither of these are critical just now, I just want to get the questions out there for later.

Usually a good flush is good enough, Get some brake clean or A/C flush & flush both ways, Flush until clean..Then flush again.

Dexron 3 ATF has all the friction modifiers needed.

Just to add.. Get some a/c flush. Its 10 times more potent than brake clean and will remove everything. We use it at work for cleaning all kinds of stuff. Our a/c part suppliers a can or two with every order.

Next step is to remove the pan, filter, Lock-up solenoid & harness, Control valve body, Auxiliary valve body, 2nd accumulator, Separator plate, 4th accumulator, & 2-4 band anchor.

The pan & filter are self explanatory,
Remove Forward clutch accumulator feed pipe...The only pipe in there.
Remove Lock-up solenoid (white arrow) & harness.
Remove the 13mm headed bolt that holds the manual detent lever spring (not shown, But the green arrow is where it will be.

Remove the Control valve body bolts (orange dots) 10mm heads.
Remove the TV valve actuator assembly.
Remove Control valve body.
There will be 2 check balls laying on the separator plate. Remove those.

Remove the Aux. valve body bolts (Yellow dots), 3 10mm headed & 1 8mm headed, The 8mm headed one is EASILY rounded off from jerks over tightening.
There will be 1 check ball under it.

Remove the 2nd Accumulator, (Blue dots) 10mm heads.

Remove Separator Plate & both gaskets, Keep the gaskets!

Remove 4th accumulator piston, Pull the center pin with pliers, Then the piston & spring.

There will be 4 check balls in the case, Remove them.

Remove the 2-4 Band anchor, Can't miss it, Metal plug looking thing under the separator plate. I use a magnet.

Accumulators & Separator Plate details, This is a 4L60E, But same concept.
