- 4l80e pressure control solenoid and diagnostics. Differences between early silver PCS and late black PCS. Great informational bulletin if your having issues with codes or drive ability of the 4l80e.

Thank you. Lots of good info. I was looking for pressure control resistance levels. Mine was coming in at 6.5 ,which is out of range because I have the new Holly pressure control, the bulletin says the Holly could measure 3 to 8. So double triple checking info, saves money and hard work. Lots good info here. TYVM
Just want to add, the bulletin says a new connector was added, the reason why was, to prevent leakage and throwing lots of codes. So this settles the Internet argument, just because tranny fluid does not conduct electricity. Somehow, the connector throws codes, when leaking. So, after checking solenoid resistance before dropping pan. I'm convinced, that all solenoids work properly, and changing the harness, should correct problems, as many people, posts talk,about, when researching the connector and internal harness and possibly external harness.
