Automatic transmission linkage adjustment. Is there a procedure in writing to follow or a flow diagram to look at. My transmission has been rebuilt and now the changing of gears takes place at higher RPMs. 1 to 2d gear shifts at around 25 MPH; 2d to 3rd at around 45 to 50 MPH. Overdrive kicks in around 63 MPH. Can this be changed?

Transmission Control Switch (TCS), Transmission Control Indicator Lamp (TCIL)
The transmission control switch (TCS) is a momentary control switch. When the switch is pressed, a signal is sent to the powertrain control module (PCM) to allow automatic shifts from first through fourth gears or first through third gears only. The PCM energizes the transmission control indicator lamp (TCIL) when the switch is off. The TCIL indicates OVERDRIVE cancel mode activated (lamp on) and electronic pressure control (EPC) circuit shorted (lamp flashing) or monitored sensor failure.
Your best bet is to take your vehicle to a qualified transmission repair shop !
Your

unit has shift linkage between throttle and transmission linkage, it has plastic bushings that hold it in place, they will get brittle with time and break, allowing linkage to come off or be out of adjustment. Have whoever rebuilt it have a look at them and replace them. There plastic, cost should be a few dollars.

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. 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.

If you have the C5 trans, here is the info:

Neutral start switch and its location on the C3 and A4LD transmissions

U most likely have gotten the transmission linkage out of adjustement, the procedure to adjust it is very involved and requires u have a factory service manual to foolow on the correct procedure, a hit and miss adjusment won't do it, u can make it worse, if the transmission linkage turns out to be in adjustment then u have an internal transmission problem

check fluid if it is a dark color and stinks transmissions probably needs rebuilt sounds like low reverse or direct clutch is bad trna will still go into loe by using forward clutch if low reverse is bad shoul be having problems with 3rd or direct in forward if forward clutch is bad

There are no easy fixes with automatic transmission but you could have the shift linkage checked to see if it can be adjusted. The neutral adjust switch may be out of adjustment or malfunctioning. It could be a number of problems but I would take it to an expert you trust because it may be something simple and they will tell you that you need your transmission rebuilt.

There is no 'adjustment' but you can check your linkage for security making sure nothing is loose or worn. Also check your fluid levels. If reverse is completely out and your starting to lose second you will probably need to have the transmission rebuilt or replaced.

The best way to adjust it is to hook a pressure gage to the TV pressure port located on the left side of the transmission just ahead of the linkage. You want it to be a zero at idle but pressure starts moving as soon as you move the linkage.
