Re: Whats needed for 4L80E swap
First of all you need a 4wd version of the 4l80. then a transfer case adapter RPM sells a cheep steel one that works just fine. However there are some billet alum. ones that are made by forum members that are very nice. 31 spline input shaft for tour transfer case. You will have to pull it apart and swap the 28 slpine input shaft for a 31 spline shaft. Available from members here or speed inc sells them . gilbert front prop shaft longer than stock is also needed . Available from Sportsmachines as well as shorted drive shaft also available from Sportsmachines. Cross member be custom built but for a drop in JSM has a nice one. Do a search here you ll find the right spot to order that. May also be available from Tom at Sportsmachines. You will have to lengthen the front transfer case brace. Can be done easily with hollow 1 " spacer and a longer bolt. Lastly a controller of some sort. Microsquirt, TCI , or standalone with controller ie Holly or BS#.
in all expect to spend 1800-2300 for the swap parts - the transmission and labor.
