So engine starts to stall when coming to a stop?
i.e. torque converter not unlocking at lower speed
This is controlled by the computer via a solenoid inside the transmission.
Computer bases its lock/unlock on speed, RPM and throttle position.
The usually problem is that the electrical connections inside trans start to fail.
But worth a look at the outside connection, unplug it and make sure all contacts are clean and dry.
Lucas makes an automatic trans additive that helps expand seals in the trans.
Automatics run on pressure, valve body seals start to leak and pressure drops a bit, additive helps to keep the pressure up.
What temp is the fluid at when driving?
Just under 200degF is where you want it, 225degF max when towing
Not sure on the full fluid exchange, really up to you, I have always been happy with just regular filter and fluid service
