So if his name is correct, he may be able to do the same on his 1992. But there is no way you can do this on a 97+ GP.

that's what we're getting at. the topic clearly states the op has a 99 MY. 99 MY GS=L67=4T65E-HD --- these are facts. and immediately he says unplug the connector and it will do what you want. obviously he doesnt really have any clue about these transmissions. It'd be one thing if he asks if it has a separate electrical plug, or asks specifically which trans it is...


i'm sure he knows stuff about the gen 1 cars. that's fine. but to assume that one knows about all transmissions in these late model W body cars too... sorry, charlie. do your homework.
