I have a 1993 bronco with electric shift. Shifts into 4x4 then while driving it slips out of 4x4 and into neutral. Press button and goes back into 4x4. To test the electronics, I put it in 4x4 and unplugged the shift motor then drove it. It slipped out of 4x4 into neutral. Plugged the shift motor back in and put it in 2x4 and drove home. Years ago, it used to slip into neutral when driving in 2x4
Transfer case slips out of 4x4

Okay to add to this thread, I have 1992 Bronco, manual hubs, and shift on the fly. 2wd has never been an issue as well as 4wd low. However it does slip out of 4wd high, and it is only on coast going forward. The 4x4 light stays on but it disengages like no power to the wheels. You stop and put it in park and it chatters on the parking pawl, so the trans is spinning. Transfer case has been replaced (reman), as well as the shift motor. The connector has been cleaned from all the old ford electric grease and all connectors look good. I have put the unit in 4wd high and pulled the shift motor and it is dead on the mark. I have also tested it without the manual hubs and not been able to get it to slip out ( maybe not enough time ). It has never done it in 2wd or 4wd low. So I'm at a loss, electrically everything seems to be working perfectly. Now I'm wondering about the coil on the front drive line, if it is some how doing this. Any help would be appreciated.
Not sure what you mean by coil on the front axle. Can you explain more?
It really has to be your transfer case. Put it in 4 hi. Take the motor off and go for a drive and that will eliminate any electrical problem chances. Leaving only mechanical.

It is an electric clutch that spins up the front drive line to match the rear speed, hence shift on the fly. The original transfer case did exactly the same thing as the reman is doing. So I agree in eliminating the electrics from the equation to figure it all out.
