Re: 1986 Turbo K5

Sweet build dude! I'm gathering parts to put a junkyard h/c/i 5.3 and 4l80e in to my 89 K5. How did you wind up mounting the 4l80e in yours? Most pickup guys just slide the stock trans crossmember back a little and redrill the holes but I haven't found any K5 guys that have used the bigger trans...

On a side note your trans sounds like it was modified at some point. Only the 2wd 4l80e's had both speed sensors in the case and the 4wd versions still had the output sensor in the transfer case (so the computer knows if you are in 4 low) and a plug where the OSS would have been in the case. GM still left the second tone ring in a lot of them so some guys are able to just remove the plug and screw in the sensor or have it added when doing a rebuild. I wasn't that lucky with my trans (from a 00 Silverado ) and didn't want to do a rebuild yet so I picked up a 32 spline np241c with VSS from a 90 Suburban.
