260DET Posted July 5, 2010 Share Posted July 5, 2010 (edited) I know that a Z32 manual gearbox will basically fit a RHD 280ZX but the tunnel has to be modified to clear the starter motor, how about a GM 4L60E auto? Anyone tried one or something similar in size? Edited July 5, 2010 by 260DET Quote Link to comment Share on other sites More sharing options...
deja Posted July 5, 2010 Share Posted July 5, 2010 I am running a 4L60E in my 77 280Z. I had to cut the stock tranny mounting ears completely out and beat on the upper area on the passenger side a bit to clear the dip stick (stock 4L60E dip stick will NOT fit I am using a Lokar).

zgeezer Posted July 5, 2010 Share Posted July 5, 2010 I know that a Z32 manual gearbox will fit without 'massaging' the tunnel, how about a GM 4L60E auto? Anyone tried one or something similar in size? I've installed an LM7 with a GM4L60E a/t and the JCI engine/transmission mounts in my Series 1 S30. Previously, the body was massaged as per the JTR manual for installation of a CSB (Gen III LT1). The driver's side tunnel was massaged with an air hammer to clear the AT shifting arm [i'm using the stock AT shifter with a rod to control the transmission shifts] About 2 hours work with air hammer and small propane torch. I have no problems at all with the AT dip stick. All of this is covered quite well in the JTR CSB swap manual. g Quote Link to comment Share on other sites More sharing options...
