If code 736 what repair is needed or what part. Is it the shift cable assembly or the selector on the tranny?

automatic trans right??? and for sure had manual box too. a/t or m/t??????????????
day1,new sold options.
check tranny linkage first, or shift cables.
and fluid levels.? good?, hot engine idle in park?
and fuses
and scan the PCM
but most times reverse failing is bad news.
aside from cable shifters failing.
the cables are 20 years old.
uses how many times, shifted now. gee huge.
and cables do fail for sure RUST there happens.
easy
the service manual tells how to check the shifter
in PRNDL, to be sure it shifts into tranny selector detents properly. , even make sure Park works can car not be able to be pushed brakes off.
a/t box names
honda.
Trans. code MZKA
or Trans. code BZKA




honda . cables shift
try new cable #14

Disconnect the shifting cable from the transmission. With the rear tires off the ground, manually shift the transmission selector into the gears to see if the problem is in the shifter cable assembly.
Depending on what chev you have, you may have a kickdown cable on the throttle assembly that is not adjusted properly.

jack up and safely go under neath vehicle and check the shift selector connection if good check cable /linkage from tranny to selector for proper connections and operations if good --try moving selector if moves try to put in neutral if hard to move or selector wont move possible internal gear damage

Shift interlock system problem . Not the cable . Your vehicle has a safety system that won't allow the gear selector to be moved from park without the brake pedal pushed . Lock solenoid keeps gear selector from moving . Trying to force it will break something . Do you know how to test electrical circuits with a volt meter ? Here is a web site for free wiring diagrams http://www.bbbind.com/free_tsb.html
Enter the vehicle info. Year , make , model and engine size. Under system click on transmission / transaxle , then under subsystem click on shift interlock . Click the search button then the blue link. Park neutral switch , brake switch and the shift interlock solenoid , check electrical circuits .

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.

Put park brake on or block wheels, and shift into neutral (if possible), If not go to tranny and pop the cable off the tranny lever (pry off with screwdriver). Turn tranny shift lever, until it clicks twice, leave here for later adjustment. Follow the cable to the adjuster, pull out the flat steel retainer clip, pinch the sides to remove cable from bracket. Remove upper covers below the steering wheel. Remove kick panel below steering colomn. Remove cable from steering wheel shifter assembly (pry off and remove clip same as at tranny). Remove the side kick panel and follow cable along floor. You may find it easier to remove the driver seat (4 nuts on floor and wiring). Pull cable thru floor and replace. Reverse procedure to install. Lock the cable and clip at steering colomn, but leave the clip off at tranny. The tranny should still be in neutral. Now turn key to run and shift the shifter into neutral. At the tranny side cable there is a white square button, press in and lock cable to lever. install retainer clip. move shifter thru ranges and ensure it locks in park. Readjust if needed by pressing button and moving shifter lever on tranny.

If it is a front wheel drive. it's under the hood. lookto the back of the engine to the tranny. where the shift cable/linkage goes to the the tranny.it's right under that. you will have to disconnect that , remove the arm, and there are two small bolts that hold it on. you might have to pry the old off. if it is a rear wheel drive it's under the car. again follow the linkage to the shift lever, about the middle of the tranny, drivers side. disassemble the same way. the new shift selector will come instruction on how to replace and adjust

is this the shift position indicator like drive, park reverse, neutral?
