The Old Guy Posted September 11, 2001 Share Posted September 11, 2001 I can't imagine why you would remove an overdrive with a lock up converter for a TH400 .I just switched my TH400 for a 200-4R .the one wire for the TH400 is for the down shift which was done with a cable on your 200.One of the wires for the 200 is for the converter and I am not sure what the other was .

Guest Posted September 12, 2001 Share Posted September 12, 2001 Go to the following site:<P><A HREF="http://www.442.com/oldsfaq/oftrn.htm#Transmissions" TARGET=_blank>Old FAQ - Transmissions</A><P>It's for Oldsmobiles, but the info should be the same for a Buick transmission. Good luck! Link to comment Share on other sites More sharing options...
