    OK, now this may have been answered, 100 other times on other posts but I couldn't find it and i looked. I wanted to get a 4 speed atlas transfer for 1st gen tacoma but in their guide they only have the 2 speed and not the 4 speed working with the tacoma due to the divorced case. is there a way around this to get a 4 speed atlas transfer with the tacoma to work?

    DIVORCED ATLAS: The “Divorce Mounted Atlas Transfer Case” has been created to give you all of the great gearing options, parts availability, and strength features to vehicles that require a remote mounted transfer case. Early vehicles sometimes ran this type independent transfer case. It was attached to the powertrain by a small drive shaft coming from the transmission. This transfer case functioned identical to others and had a front and rear driveshaft. The entire transfer case assembly was hung from the frame on a crossmember-type mount. The Divorced Atlas can be built as either a right or left drop unit. The shifters and crossmember are sold as a separate kit to fi t the transfer case. When ordering yokes for this unit, 3 are required. The mount plate included in our kit will give you the rigid mounting location for supporting this gear box to the frame. Prothane bushings and all hardware are included in this kit. It is necessary that you fabricate a support bracket from our transfer case mount to the frame rails of your vehicle. Please be aware that this new mount bracket is very rigid and should be able to withstand the extreme twisting load that the gearing of the Atlas transfer case creates. Keep in mind that a good amount of frame fl ex may be generated in severe offroading conditions. We only offer the divorced units in the 2 speed configuration. Atlas 2 Speed: P/N A-DIV-T3 Left Drop Case Mount and Cable Shifters: P/N 303025L Right Drop Case Mount and Cable Shifters: P/N 303026R Toyota Tacoma, Tundra, and 4Runners: For Toyota Tacoma 1996 to 2004, Tundra with the 4.7L Auto trans 1999-2006, and 4 Runners 1996-2002 with 3.4L V6 & 2.7L Auto trans., we use a 3/8” adapter plate that couples the Atlas to your transmission. We offer the Atlas in either a left or right drop, left being for stock installations. The Toyota transmission either had a 23 spline or 26 spline stock output shaft. Our spud shafts couple to either one of these splines and then provides a Jeep 23 spline output. Adapter kits would either be P/N 50-5710 (23 spline) or P/N 50-5711 (26 spline). The Atlas would need to be ordered with the following input: Atlas 2 Speed: P/N A23Short

    I could also be reading this wrong and it could be referring to the pre Tacoma, Toyota pickup but they don't list part number for 4 speed under tacoma

    He knows Toyota transfer cases and may have a different option.

    The Atlas two speed transfer case is fun to stuff under vehicles. Couldn't imagine a four speed.

    Yes, fitment may definitely be an issue, but I want to put something in there that will work for whatever I decide to do in the future as I bought the truck for a project and I'm not sure what that project will turn into at this time my thought was to get something strong that will work in almost every situation.

    Im not much help here. Atlas and 1st gens are not my area of expertise so I have to punt to @Wishbone Runner on this one. He put a 4 speed atlas in his 04 runner so it should be possible.

    If you cant find answers here, I would call up advance adapters and see if you can speak to someone knowledgeable on the product offerings.

    I can speak to my experiences with marlin and NWF boxes on my 2nd gen, if OP is interested in those options.
