Question about Ford F-150

My 88 F-150 AOD 4wd shifts hard into overdrive (kinda bumps into and out of overdrive) It shifts in and out at the correct speeds its just not smooth. I bought the truck from the original owner and he told me it had always been this way.

Fairly normal.
It is a planetary gear system with a conic frustum shaped clutch. So it tends to grab fast and hard. That is good, because then it wears less.

HAVE A 1989 FORD F-150 WITH AUTO TRANS THAT YOU CAN'T SHIFT OUT OF THE "PARK" POSITION AT THE STEERING COLUMN. THE TRANY CAN BE SHIFTED AT THE TRANS WHEN LINKAGE IS DICONNECTED.I THINK THE...


What trans? AOD? This is 1992 F Series, all I have.

Shift Controls, Automatic Transmission The transmission shift control linkage or cable transfers the transmission operating mode from the selector lever to the transmission. The indicated transmission position on the steering column is transferred to a shift lever on the bottom of the steering column. On vehicles equipped with cable-operated shift systems, the indicated position of the transmission selector lever is transferred to the transmission through the shift cane, then to the cable, and down to the transmission manual shift lever at the transmission. On vehicles equipped with shift rod assemblies, the rod transfers the indicated transmission selector level position through a bell crank assembly to a control rod. The control rod transfers the indicated position to the transmission assembly.
----------------------------------------------
Automatic Transmission Manual Linkage Adjustments
  1. With the engine stopped and the parking brake applied, place the transmission selector lever at the steering column in the D (DRIVE position) for C6 applications and in the (D) (OVERDRIVE position) for AOD and E4OD applications, and hold against the D or (D) stop by applying a three-pound force to the selector lever knob.
  1. Loosen the shift rod adjusting nut at point A. Refer to the following illustrations.
  1. Shift the manual lever at the transmission into the (D) (overdrive) position for E4OD, by moving the lever all the way rearward, then forward two detents.
  1. With the selector lever and transmission manual lever in the(D) position, tighten the nut at point A to 17-24 Nm (12-18 ft-lb) torque. Use care to prevent motion between the stud and rod.
  1. Remove the three-pound force from the steering column selector lever knob.
  1. Operate the shift lever in all positions to make certain that the manual lever at the transmission is in full detent in all gear ranges. Re-adjust the linkage if required.
  1. On F-Super Duty Chassis Cab and Motorhome and Commercial Chassis recheck for correct operation of the automatic transmission selector indicator (PRN(D)21). Refer to Section 11-04A, Steering Column, Shift Rod Within Tube. ani_caut.gif CAUTION: Under no circumstances will it be permissible to adjust linkage in any position other than the(D) position for E4OD applications.
---------------------
Automatic Transmission Shift Cable Adjustment
  1. From inside the vehicle, place the column shift select lever in the DRIVE position (C6) of the OVERDRIVE (AOD and E4OD). Hang a three-pound weight on the selector lever.
  1. Raise vehicle on a hoist.
  1. Remove the shift cable from the transmission lever ball stud.
  1. Pull down the lock tab on the shift cable body.
  1. Position the transmission shift lever in the DRIVE position (C6) or the OVERDRIVE position (AOD and E4OD). This is three detents from the front-most lever position with the first position counting as one.
  1. Connect the cable end fitting to the transmission lever ball stud.
  1. Push up on the lock tab to lock the cable in the correctly adjusted position.
  1. Lower vehicle down from hoist and remove the three-pound weight from the column shift select lever.
  1. After making the adjustment, check for park engagement. Check the transmission control lever in all detent positions with the engine running to make sure correct detent/transmission actions. Readjust if necessary.

Honestly, while there is a chance that there is a bigger problem, it sounds more like its time for a transmission service. Hard thunking shifts when starting or stopping with no other apparent symptoms on older vehicles can usually be corrected by a transmission flush. if you pull out your tranny dipstick and the fluid is any darker than bright red and/or smells burnt (smell should make you cringe a bit) then take it to a shop and get it flushed out. I recommend a service center that uses a BG power flush unit. These services seem expensive on the surface but only have to be done about once every 3 years and can prevent more costly and involved repairs down the road.

Mech or Elec overdrive


According to Haynes Auto Repair Manual, section on automatic transmissions, the 1994 Towncar has the AODE transmission
Baumann Electronic Controls website
URL: http://www.becontrols.com/tech/ch1alphabet.htm
has following:
The Automatic Overdrive (AOD) transmission was introduced in 1980 as Ford's first four-speed automatic overdrive transmission.
The AOD-E transmission is essentially a beefed-up electronically-controlled version of the AOD.
If this doesn't answer your question, you might troll around the website.

Ford transmission 86 4wd will not shift to high gear


It is hard to say from your description what the problem is ... could be linkage issue ... could be trans is going as is with the other poster ...
Losing overdrive. Clutches (bands/clutches) have had it. Be careful driving without that top gear ... doing too high a speed without the appropriate gear causes extra stress on your engine that could accelerate further problems. Try to do only driving at a low enough speed that the top gear is not missed ... will help the vehical last as long as possible.
