It wont up shift if the throttle valve cable is not adjusted correctly.
What are the odds that you will have two 89 fords with the identical problem? can you give more info? You said you replaced the one, with what, the other? or another trans?my two 1989 ford f150s both have reverse and first but no other gears. both have the aod. I replaced the one transmission and same results could it be the torque converter? I am stumped.
it could be the late upshift, but i do remember mine shifting. the TV cable is just like the old kickdown rods, but adjustable...
I am understanding it to mean, you used the tranny off the vehicle with the seized engine but am unsure how you saw it run and shift fine?I had replaced the transmission with a working one. I saw it run and it shifted fine... I put that transmission in but with the old torque as the motor was seized in the one I took the transmission out of.
THROTTLE VALVE CABLE ADJUSTMENT
AOD Transmission With Fuel Injection
ADJUSTMENT WITH ENGINE OFF
- Set the parking brake and put the selector lever in Neutral.
- Remove the protective cover from the cable.
- Make sure that the throttle lever is at the idle stop. If it isn't, check for binding or interference. NEVER ATTEMPT TO ADJUST THE IDLE STOP!
- Make sure that the cable is free of sharp bends or is not rubbing on anything throughout its entire length.
- Lubricate the TV lever ball stud with chassis lube.
- Unlock the locking tab at the throttle body by prying with a small screwdriver.
- Install a spring on the TV control lever, to hold it in the rearmost travel position. The spring must exert at least 10 lbs. of force on the lever.
- Rotate the transmission outer TV lever 10–30°and slowly allow it to return.
- Push down on the locking tab until flush.
- Remove the retaining spring from the lever.
SHIFT LINKAGE ADJUSTMENT Shift Rod
- With the engine stopped, place the transmission selector lever at the steering column in the D position for the C6 or the D overdrive position for the AOD and E4OD, and hold the lever against the stop by hanging an 8 lb. weight from the lever handle.
- Loosen the shift rod adjusting nut at the transmission lever.
- Shift the manual lever at the transmission to the D position, two detents from the rear. On the F-150 with 4WD and Bronco, move the bell crank lever.
- With the selector lever and transmission manual lever in the D or D overdrive position, tighten the adjusting nut to 12–18 ft. lbs. (16–24 Nm). Do not allow the rod or shift lever to move while tightening the nut. Remove the weight.
- Check the operation of the shift linkage.
