Hard to shift out of park
I have a 95 Aerostar that when in park it is hard to shift into reverse, drive etc. It is an automatic, 3.0 liter. Please help
|
I have this same problem. The shifter also moves around while in any gear, its like its loose. But I can't tell how to fix it!
|
The shifter doesn't move but I have to press the brakes really hard to get it to shift.
|
Thats exactly what mine does. I can have the brake pedal to the floor, and it feels like I have to rip the level down just to get it into whichever gear.

Shift Interlock System
The shift interlock system prevents the shifting from PARK (P) (when the ignition switch is in the RUN position) unless the brake pedal (2455) is depressed. The interlock system consists of an electrical solenoid mounted at the base of the steering column (3C529). If the ignition switch is in the RUN position, the solenoid has continuous power supplied unless the brake pedal is depressed Brake-Shift Interlock Switch The brake-shift interlock switch (used on automatic transmission-equipped vehicles) prevents moving the shift lever out of PARK position unless brake pedal is depressed. The brake-shift interlock system consists of an electrical solenoid mounted at the base of the steering column. If the ignition key is in the run position, the solenoid continually runs unless the brake is depressed. <table border="1" cellpadding="3" cellspacing="0"> <caption>SUMMARY OF INTERLOCK OPERATIONAL STATUS </caption> <tbody> <tr> <th align="center" valign="bottom">Ignition Switch Position </th> <th align="center" valign="bottom">Ignition Interlock Shift Lever and Steering Wheel </th> <th align="center" valign="bottom">Brake-Shift Interlock Status </th></tr> <tr> <td align="center" valign="top">Accessory </td> <td align="center" valign="top">Locked </td> <td align="left" valign="top">Shift Unlocked — No Power to Solenoid </td></tr> <tr> <td align="center" valign="top">Locked </td> <td align="center" valign="top">Locked </td> <td align="left" valign="top">Shift Unlocked — No Power to Solenoid </td></tr> <tr> <td align="center" valign="top">Off </td> <td align="center" valign="top">Unlocked </td> <td align="left" valign="top">Shift Unlocked — No Power to Solenoid </td></tr> <tr> <td align="center" valign="top">Run </td> <td align="center" valign="top">Unlocked </td> <td align="left" valign="top">Shift Locked (Unless Brake Pedal Is Depressed) — Power to Solenoid </td></tr></tbody></table> If the brake circuit fuse is blown or the solenoid has internally shorted, the vehicle will not shift from the PARK position even if the ignition is on and brake pedal is depressed. The interlock can be temporarily overridden by the following procedure:

NOTE: Perform the transmission control cable adjustments in the order in which they appear in this section of the manual. Before the cable is adjusted, be sure the engine idle speed is within specifications. Refer to Section 4A of the Powertrain Control/Emissions Diagnosis Manual for diagnosis and testing of engine idle speed. NOTE: Before adjusting the control cable, the shift indicator needle must first be checked for proper positioning and adjusted if necessary. Refer to Section 11-04A .

Thanks a lot I really think it is the BOO switch because when I override it there is not a problem. Also, I don't have problems in other gears.
|
Also check the shift tube in the column area. It has 3 torx bolts that seem to come loose often. Cause hard shifting out of gear too.

Great post 96_4WD, thanx!
