Hi guys, looking for some information. I have a 87 442. All stock with 49,000 miles. 200r4 trans and I am having an issue. It shifts up thru the gears very quickly into overdrive and then does not want to down shift unless you come to a complete stop. It doesn't do it all the time, I have serviced the trans, new fluid filter etc but the problem persists. Any ideas?

It's most likely the TCC solenoid (Torque converter clutch solenoid)
It's super easy to replace but you do have to drop the pan again.
Simple 2 wire hook up and bolt in.

Check your TV cable setting. A TCC solenoid, when stuck on will cause stalling at stops.
maybe you need this on the transmission linkage

The correct selector lever bushing GM part number is 10021797 for an 87 442.
But I don't think that's necessarily the problem. I think he means that when shifting itself, not manually doing it.
