tis a new filter..

Does the Fiero automatic use a TV cable? If so, it has to be properly adjusted for the transmission to shift properly.

i think so, thats the one that goes to the TB right? how do i adjust that
Formula88 AUG 01, 05:35 PM
Not sure. I've never had an automatic Fiero. I'll see if I can look it up in my shop manual.
If you have a Haynes or Chiltons manual, they might also have the procedure.
I do know on other cars that the TV cable affects shifting and if it's not hooked up and properly adjusted, it could damage the transmission. Or so I've been told.

I'll see what I can find out if someone doesn't post the info here first.

Here's a couple threads discussing aadjusting the TV cable...

but from what i see, that affects shifting while driving.. it seems like my driving shifting is fine.. it just takes a minute to get INTO gear (im guessing build pressure..)

this is what happens..

i put it in gear and release brake.. nothing

i up it to 2k for about 30 sec's then itll move.. once moving.. its fine from R to D takes a sec.. but once i put it in park.. i have to rev it a bit again to get it to move...


is it possible theres air in the system, and everytime i turn the car on, it compresses the air till it works?
BobadooFunk AUG 02, 05:10 AM
messed with TV cable, no difference.. checked fluid, full.

is it possible not enough fluid in the actual torque converter? air in system?

You might not have enough fluid in the torque converter for it to work properly. I'm guessing you have a bad or sticking valve or modulator. You can read about how the torque converter works here http://auto.howstuffworks.com/torque-converter.htm

Here are some things that can cause tranny failure from the Wikipedia article on torque converters.

Overloading a converter can result in several failure modes, some of them potentially dangerous in nature:

Overheating: Continuous high levels of slippage may overwhelm the converter's ability to dissipate heat, resulting in damage to the elastomer seals that retain fluid inside the converter. This will cause the unit to leak and eventually stop functioning due to lack of fluid.
Stator clutch seizure: The inner and outer elements of the one-way stator clutch become permanently locked together, thus preventing the stator from rotating during the coupling phase. Most often, seizure is precipitated by severe loading and subsequent distortion of the clutch components. Eventually, galling of the mating parts occurs, which triggers seizure. A converter with a seized stator clutch will exhibit very poor efficiency during the coupling phase, and in a motor vehicle, fuel consumption will drastically increase. Converter overheating under such conditions will usually occur if continued operation is attempted.
Stator clutch breakage: A very abrupt application of power can cause shock loading to the stator clutch, resulting in breakage. When this occurs, the stator will freely counter-rotate the pump and almost no power transmission will take place. In an automobile, the effect is similar to a severe case of transmission slippage and the vehicle is all but incapable of moving under its own power.
Blade deformation and fragmentation: Due to abrupt loading or excessive heating of the converter, the pump and/or turbine blades may be deformed, separated from their hubs and/or annular rings, or may break up into fragments. At the least, such a failure will result in a significant loss of efficiency, producing symptoms similar (although less pronounced) to those accompanying stator clutch failure. In extreme cases, catastrophic destruction of the converter will occur.
Ballooning: Prolonged operation under excessive loading, very abrupt application of load, or operating a torque converter at very high RPM may cause the shape of the converter's housing to be physically distorted due to internal pressure and/or the stress imposed by centrifugal force. Under extreme conditions, ballooning will cause the converter housing to rupture, resulting in the violent dispersal of hot oil and metal fragments over a wide area.

Did the tranny ever come out? If it did you're supposed to pour oil directly into the torque converter (according to my reading and an episode of monster garage) much like putting oil in the oil filter during and oil change.
