idle issue on an 88 k5

[root beer 88]

Im gonna keep picking your brain 4x4high lol

My k5 also has a lokar kick down cable that the previous owner had installed when the trans was rebuilt with a firm shift kit and it idles in park at 1000rpm and in drive its around 500-600 with the misfire bouncing it around a little... Should i replace that with a stock detent cable?
And are those about the normal idles?

First if you have a 700R4 it IS NOT a kickdown cable, it's a TV cable and it controls throttle pressure. It's not even close to what a kickdown cable does.

The idle should be 550rpm in drive. There is a procedure for adjusting minimum idle air (this IS NOT the same as idle speed on a carb). I have that procedure if you need it.

Yeah its a 700r4 with a firm shift kit... I saw that it was a lokar cable instead of a regular detent cable and when i did some looking around the lokar inc. website the only thing i saw were kickdown cables so im thoroughly confused lol

Im ok with the idles where they are i just wasnt sure if they were within normal parameters.

Should i switch that detent cable back to a stock one?

Lokar does make a TV cable for the 700R4 so I wouldn't worry much about it unless you're having issues with the trans.

Trans shifts fine im still getting used to how far apart the shift points are compared to my 2001 gmc sierra lol
