Hey I just inherited a 1990 Ford bronco the frame and everything is great but it’s stuck in four-wheel-drive. Is there something I can fix myself or should I take it to the shop?

Yo Nikayla,
Welcome!
"The Borg-Warner 13-56 is a chain-driven transfer case (7A195) in which the shifts may be activated electrically or mechanically. The basic functions of this system are much the same as any other 4x4 transfer case.
With the electronic shift transfer case, by touching the control switch on the instrument panel, the driver can select either 2- or 4-wheel high plus 4-wheel low range, if conditions require. With the manual shift transfer case, speed selection is controlled by a single-lever shift mechanism that provides neutral, 2-high, 4-high and 4-low.
The Borg-Warner 13-56 manual shift transfer case is a three-piece transfer case. The case (7005) is magnesium, except for F-350 applications which have an aluminum front case half and an opening for a power takeoff (PTO). It is a part-time transfer case for a power takeoff. The unit is lubricated by a positive displacement oil pump that channels oil flow through drilled holes in the rear output shaft. The pump turns with the rear output shaft and allows towing of the vehicle without disconnecting the rear driveshaft."

1356 Electric Shift Emergency Shifting; "... I recall in same thread Ricky B wrote this[/url]; I'd thought I'd share some pics for those who may like to know what the t-case 12 volt shift motor does.

If it's manual chances are the shifter pivot froze and you'll have to take it apart like these photos to git it movin' again.

LONG SHOT IS No Movement or Neutral Position Tip/Saver Spacer & pic; "...Many 1987-1995 Ford F series 4x4 trucks and full size Bronco owners with 1356 manual shift transfer cases commonly complain of a "no movement" or an occasional neutral condition. This condition is usually caused by the linkage wearing the transfer case at its point of contact. Sonnax offers a case saver spacer 36605-01. This case saver spacer goes between the shift selector cam and the case and requires no special tools to install. The spacer moves the cam closer to the shift fork, thus preventing and/or eliminating: 1) one or both shift forks from becoming disengaged from the shift cam, 2) "slop"from the linkage caused by a worn linkage bore in front case half. This item is a specific size/thickness not commonly found in ordinary flat washers. This repair is quick, easy and a lot less expensive than repairing or replacing the case. Model: 36605-01..." SPACER IS NOT AVAILABLE!
Local transmission shop should be able to help find or make the spacer.

Manual or Electronic Fluid Level Check
Remove the fill plug from the transfer case. Fluid level should be just below the fill plug. If the fluid is below the level, fill with MERCON V (also used in E4OD Transmission),●

Crawl under it and look for the rods. They might need greased up. A garage will probably charge you $100 just to look at it.

reverse/forward/reverse/forward almost like rocking? No? Thena:
Mine (1st gen) never goes in (a different design tho) w/o a 'roll back' (some call it 'unwind') of 3, 4 ft.
Ck pins'n linkage. C an exploded diagram if unfamiliar w/how urs wrks?
Oh! it's ele? Get out test light for continuity tests, do a fuse search...
No? go onto miesk's trouble shooting guide above...

Hats off to Miesk5 for this info.
My 4X unit was DOA when acquired.
This will go a long way towards correcting that issue.
