Question about 1983 Ford F150

2 Answers

Transmission on a 1983 f100 with a overdrive automatic. it's shifting well now that I adjusted the kickdown linkage but won't shift into overdrive until about 50-55 mph and only if I let off the gas a little. I would like it to shift into OD at about 45. What are the specs on adjusting the linkage?

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.

Your transmission is the ford AOD,
you cannot safely adjust the tv cable for shift timing.
the tv "kick down cable" is for throttle angle input to the transmission, this cable pulls a lever in the valve body which interacts with the throttle valve, this is how the line pressure is adjusted in proportion to throttle angle, if this cable is misadjusted than transmission failure will soon follow.

it takes a pressure gauge and a great deal of knowledge of this transmission to set the cable correctly.

please take your vehicle to the nearest transmssion shop and have that cable adjusted properly ASAP.

as for the shifting issues, this could be a plugged filter, poor fluid quality, valve body malfunction or governer malfunction,

get your cable adjusted correctly, if that does not resolve your problem than contact me at wesleyschacht@hotmail.com and i can walk you through further diagnostics.

93 ford tempo, changed neutral safety switch. worried i may have broken the kickdown lever, reattached all the linkage to it and now the transmission won't shift into 2nd gear until about 35mp


What about the rest of the shift points. 2 to 3 and 3 to 4? If the others are normal than the problem is with the 1-2 internals and not the T-V linkage.
It seems the transmission Is acting as if the throttle is wide open; for the 1-2 shift, therefore there is something in the linkage is broken or out of adjustment since your work. The last step before opening up the transmission to replace the TV linkage is to make sure the external TV cable linkage is set up right, and after is verified, if you are still seeing WOT upshift points that function of the internal to external kick down parts will need to be repaired. Sorry.

If you know a good local independent transmission specialist you might see him and get some advice.

Tip

Throttle Valve Cable Ajustment on a 2nd Gen Dodge Ram


<b> <p>Before you begin:<br /></b> <p>This tip is to show second generation Dodge Ram truck owners with the automatic transmission how to properly adjust the shift points of their transmission. These pictures are from my 1999 Ram 1500<br /> <p>with the 5.9 liter V-8 engine. When I bought my truck, I quickly decided I didn't like the factory set shift points. It shifted too soon under light and medium throttle...and passing gear/kickdown required a lot of gas pedal to achieve. My desire was to have the 1-2 shift and the 2-3 shift occur at a higher road speed/<br /> <p>engine rpm and to have a more sensitive kickdown. In my case, this was accomplished by adjusting the transmission throttle pressure cable only 1/4" (0.25 inches). What is the throttle pressure cable? Between the throttle linkage and the driver's side of the transmission there is a cable that causes a valve inside the transmission to move in relation to throttle position (gas pedal position). This cable is also referred to as the Throttle Valve (T.V.) cable.<br /> <p> <br /> <p>What does it do? The T.V. cable moves the throttle valve in the transmission.....which in turn controls THREE things: <br /> <p> <br /> <p>1) the transmission line pressure and <br /> <p>2) the transmission shift timing and<br /> <p>3) the transmission kickdown (or passing gear). Many people mistakenly believe it only performs function number three.<br /><b> <p> <br /> <p>Very important:<br /></b> <p> <br /> <p>l More throttle opening = HIGHER line pressure and LATER, FIRMER shifts.<br /> <p>l Less throttle opening = LOWER line pressure and EARLIER, SOFTER shifts.<br /> <p>l WOT (Wide Open Throttle) = MAXIMUM line pressure and FIRM shifts at the engine <b>redline</b>.<br /> <p> <br /> <br /> Even though this walkthrough is for 2nd gen Ram's, most cars and trucks with automatic transmissions will have similar T.V.C. setup and adjustment.<br /> <br /> <br /> This picture shows the location of the throttle pressure cable adjustment<br /> <p> <br /> <img src="kacomstock.png" /> <br /> <br /> Here's a close up of the bracket and adjustment mechanism<br /> <br /> <img src="kacomstock.jpg" /> <br /> <p>Here's what the locking clip actually looks like:<br /><b> <p> <br /> <p>When removing this clip, be aware that it is plastic and be careful that you don't break the tabs off when prying on them.<br /> <p> <br /> <p> <br /></b> <br /> <img src="kacomstock_0.png" /> <br /> <br /> Here is a close up of the T.V. cable and locking teeth.<br /> <br /> <br /> <img src="kacomstock_1.png" /> <br /> <br /> <p>For LATER, FIRMER shifts, slide the cable housing further OUT of (rearward) the locking mechanism. Attempting to make the shifts too late and firm will result in undesirably harsh shifts under light throttle.<br /> <p> <br /> <p>For EARLIER, SOFTER shifts, slide the cable housing further INTO (forward) the locking mechanism. Attempting to make the shifts too early will result in excessive transmission slippage during shifts, especially at medium and heavy throttle.<br /><b> <p> <br /> <p>WARNING: Going too far in either direction will cause trouble!!<br /> <p> <br /> <p> <br /> <p> <br /> </b><img src="kacomstock_2.png" /> <br /> <p>BEFORE you begin, make note of the cable position so you have that as the stock reference point.<br /><b> <p> <br /> <p>Make your adjustments in small increments of about 1/8" (0.125")<br /></b> <p> <br /> <p>At a fixed throttle position...say 1/4 throttle....every 1/8" of cable adjustment will change the shift points by a few miles per hour. At a greater throttle opening...say 3/4 throttle... that same 1/8" of cable adjustment will make more of a difference.<br /> <p> <br /> <p>When you're finished adjusting, replace the locking clip and road test it. Pay close attention to the light and medium throttle shift firmness and timing.<br />

Having problems with my Automatic transmission Kickdown, when i press the accelerator pedal all the way down, the gears will not shift, and the gears will not kick down going uphill, i have to manuall


Most cars with automatic transmissions have a kick down switch that is sometimes mounted on the transmission but activated by the throttle linkage. A good mechanic should be able to correct this quite easily.

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.

What do I need to do to make a ford overdrive Transmission out of a 89 van work in my rat rod?


Only things is to have the proper tv kickdown cable, lokar makes one for good price and if you don't have proper shift linkage, lokar also makes what you need for that, just be sure the kick down cable is adjusted properly or you'll burn it up.

My Volkswagen will not shift into park and jams a bit going into reserve. Drive and overdrive are fine. Does this mean my transmission is bad?


Sounds like the shift cable is out of adjustment. I have to admit that I am not totally familiar with the TDI set-up but the automatic transmission cable moves a linkage on top of the transmission. If the linkage bushings are worn, the cable may not be able to "push" the linkage to park. If the car shifts fine and does not slip in any gears, the transmission is not bad.

88 silverado wont shift into 3rd or overdrive


Good place to start, Make sure all cables & linkages at transmission are moving freely, especially kickdown. Spray with penetrating spray if appear stiff. With vehicle off & in park, have someone push gas pedal to floor & you watch linkages at transmission to see what they do, then when gas pedal released slowly, watch again where they return to & see if a little force (by hand) will move them in that direction a little further. If they do appear stiff or slightly seized, that's where you want to spray. then work it until it comes all the way back itself, then try it & see if it's any better.

Transmission wont shift


check the kickdown/throttle valve cable. It may be bound up and stuck in the maximum position giving you extremely late shifts.
