Transmission Maintenance

[js39]

What periodic maintenance needed to keep the transmission fully tuned. A 2000 silhouette with Pressure Control solenoid just recently replaced with some tranny fluid change. But it doesn’t have the full fluid flush and filter change yet. I heard something about sometimes there is some gunk/sludge buildup cause tranny to go sluggish.

Stay away from these full flush machine techniques, was the fluid clean and not burnt before the pcs repair, if so you are good, maybe add a bottle of Lubegard red.

Thanks for the reply. Yes, transmission fluid was good and never burnt. What is a Lubegard? MAF, Cylinder Misfire and lagging PCS codes were set. MAF was cleaned; STP GAS Treatment was added to the fuel (returned excellent gas mileage after the PCS replacement) for misfire remedy. Axle seal also replaced. Now I an not sure a remedy for slow pickup (no slipping observed) from a full stop could either be fix by a transmission filter replacement (not advised by dealer) or start by replacing sparkplugs (still have original, van just crossed 100k), air filter, fuel filter, and PCV valve.
