Hoping someone has some expertise with the TH350. I completely rebuilt the TH350 for the 77 K10. It is reinstalled along with the engine. I replaced the kickdown cable. I have the kickdown cable attached to the throttle body (upgraded to fuel injection). When I manually open the throttle to WOT, the kickdown cable will 'pull' the kickdown wire & activate the valve in the trans. The issue, if it really is an issue, is when I return the throttle to closed, the kickdown mechanism (valve in the trans) is not returning. If I give it a small 'nudge' at the carb end of the cable (push it back in), it will go back to normal position. Is this normal? Bear in mind the engine is not running. Also, I have not put any trans fluid in the unit yet - only assembly lube during the rebuild. Would either of these cause this 'sticking' issue? Is there a spring inside that valve that is supposed to pull the cable back when the throttle is closed? Does it require the engine to be running (ie: trans fluid pressure) to pull the cable back? I am wondering if I need to pull the pan back off to see what's going on. Or of this is totally normal and to not worry about it. Thanks.
