Hey third gen, my 92 trans am seems to shift really hard when you put it in gear and when driving it seems to be a little better but still shift hard as it goes through the gears. Fluid looks brand new and trans was rebuilt, I aont know if it was done correctly or not as it was the previous owner. I was thinking theshift linkage could be the problem? Thanks, Bryce

 

Shift linkage = no way . The shift linkage has nothing to do with how hard it goes through the gears while driving .....

That would be the job of the throttle position cable that runs from the throttle to the transmission . this cable is commonly mistaken for a "kick down" cable and in reality it's very much more than that . It controls the "line pressure" within the transmission based on throttle setting and is most certainly responsible for how hard or soft it goes through the gears (as well as a couple of other important transmission operating parameters as well) . If this cable is not properly set , the transmission can be damaged and there is only one proper way to set it right . This is NOT an "adjustment" , there is no "range of setting" for it , It's either set up properly , or it isn't .

Do a quick search for "TV Cable setting" to find the right procedure for setting the cable correctly and hopefully it'll cure your hard shifts ....

 

Okay thank you would you suggests getting a new one or just adjusting the stock one

 

Could it still be the tv cable because my car mainly has trouble going into gear

 

By all means you should attempt to set correctly what is already installed on your car , and only if the set procedure fails should you consider parts replacement . Far too many folks get this mistaken notion of "I'll just replace everything with new" , this is called the "shotgun" approach and is not real troubleshooting . If , per chance , your cable is set properly , well then your problem very well will be further into your transmission such that a new cable will not fix it and be money wasted . Thing is , the only external component that could be causing your problem is the TV cable , and so must be found out first as to whether it's set properly or not .

Where your shifts are harsh , It sounds as if the cable might be misadjusted in the "too tight" direction . The way it works is , the more you step on the gas pedal , the more it pulls on the TV cable , which "tells" the transmission how much to draw out the shifts and how hard (or soft) to engage the shifts . When your really stepping on it , it will hold each gear longer and shift more firmly into the next gears . When your not really stepping on it , the shifts happen sooner and softer . If the TV cable is making the transmission think your stepping on the gas more than you actually are , maybe it won't allow itself to go into gear at such a (mistakenly perceived) high throttle setting ????

Bottom line , again , is to do a search of how to properly set that cable , do it and do it right , and if this fails your problem WILL be somewhere within the transmission itself .

PS , before ya ask , the ECM (computer) has exactly nothing to do with when , or at what force , the transmission shifts , and controls the lockup of the converter only .

Best of Luck with it , and please post the results of your hopeful success in setting the TV cable and solving the problem .....

 

Alright thanks I'll keep you posted
