Hello,
I posted a similar thread in the Engine Tech area but realized it is probably not an engine problem...
Car: 1988 Cougar XR-7, stock 5.0, Floor shifter, 179,000mi.
Problem:
Car will not shift until it reached 3000-3500rpm depending on how much throttle I'm giving it. It will also jerk into lower gear when letting off the throttle (and braking). It was working fine, then one day a week or so ago started doing this..Thought it might have been the TV/Kickdown Cable but I accidentally broke the rail on the block mechanism near the throttle body and have removed it as I assumed it is only needed to kick the car down into passing gear...
That being said, I have also looked for a transmission MODULATOR, to check for a bad vacuum or part only to discover that the transmission has no modulator (there are not vacuum lines running from the tranny at all, just the steel lines to the radiator..the tranny was replaced about 3-4 years ago and reads "FORD AUTOMATIC OVERDRIVE METRIC" on it)...I have also checked the fluid color and level and everything checks out.
Does this mean that I have an internal problem with the tranny, or is it something else causing the long, harder than normal shifts?
Thanks in advance!
Paul
The kickdown cable controls the line pressure and determines when it will shift MUST be hooked up...
9 posts directing you to attend to the TV cable and you still ask? :rollin:
Not to be a jerk, but fix the TV cable....if it still does it, I'll publicly apologize, and we'll go from there...
My money's on that cable though ;):D
If you ask I will go out and take a picture of what goes wrong and where it is. Stop driving the car if you like it and get it fixed. The longer you drive the more and sooner it will be broken.
i went throu the exact same thing its that tv cable, anyone kno where to buy one?
I will get a new cable asap...looking in junkyards...the thing is that the TV cable was fine until I started to mess with it and it broke..after I removed it acted the same but if this is the problem I will fix immediately then re-post...I apologize for my ignorance as I am unfamiliar with AOD's..Thanks for the heads-up!!!
Haystack...can u send a pic...I'm a noob when it comes to transmissions....pjn2557@msn.com
You guys are lifesavers!
I will have a pic for you tommorow night.
I wonder why they replaced the TV rod with cable that's pr0ne to breakage? Maybe the rod was less accurate?
If you drive the car without the TV cable hooked up you're going to fry the AOD.......
If you absolutely MUST drive it without the cable...at the very least...tie off the lever that the cable tugs on so it's like 1/2 way - 3/4 of the way to it's full throw. This might be a BAD idea so don't do it until someone comes in and corrects me if I'm being my usual idiotic self...but I feel like that should put the TV pressure at a decent level so if you STAY away from full throttle it will shift with enough hardness so as to not burn everything up.
Really though...you should definitely not move the thing until that cable's replaced! ;)
Probably already has.:punchballs:
Not on late/hard shifts... It's the early, mushy shifts the screw the clutches... Due to type of TV arrangement(cable or cable and linkage), a broken cable can cause two different symptoms, which are exactly opposite to each other...When it fails, the cable & linkage system allows the throttle valve to go to full pressure, while the full cable system drops TV pressure to zip, burning up the clutches ...
I have not driven it since it broke b/c I was afraid it would fry..Just waiting to find a new tv cable...only ones I found were for $70 online and I don't have that kind of $$...
This it the type of cable I have (attached); I believe it is the cable/linkage not full cable type, correct? Does that mean I can drive it for a short distance? I have to go to the airport on Friday morning and can't find a ride yet...
FYI, i had the same problem and it was the TV cable. I have read sevral posts that say dont even drive it to the parts store cuz you will fry the trans. Get a cable from the junk yard or post an ad in the "wanted". Penty of cars being parted out. Also make sure you get a new bushing where the TV cable hooks to the throttle body.
Hmm I didn't know that. Thanks. My car has the cable and linkage since it has a column shifter.
pjn2557 you have a floor shifter so you have the full cable. Don't drive it till it's fixed.
Check the lever at the trans to make sure that its returning all the way.i had to put a spring on the lever or my trans does the same thing.second get a locar cable they are more adjustable i like mine.summit has them
My transmission is acting the same way. It will still go into OD but not until likr 43 or 44 when it used to do it at 40. The motor went into the car a year ago and the tv cable was set. Are they move out of alignment this frequently? I'm in college and don't drive the car too often, I'm worried if I realign it, it'll come back out shortly.
Suggestions?
watch the bad shoe productions video on setting the TV cable. If that doesn't fix it, time to talk to a transmission shop if you want to keep the car drivable.
what video? I'm sorry? I set it according to the Blue Ford Manulas. Bad shoe production? what?
