trans dosent kickdown to first hot at times
 

Need some ideas for this problem where to look, at times my 94 wagon with 104 engine dosent kickdown when i floor it, i notice it only when hot, when its cool or warming up it will always kickdown from 2nd to first gear, this is anoying me ,stop light to stop light hot starts in 2nd gear and its slow at times , most of the time its fine, where do i start to look first?

Three devices in the kickdown circuit....fuel pump relay, kickdown switch and kickdown solenoid.
Completed circuit is one wire and operates to ground...

Im suspecting kickdown switch , carpet is kinda shrunk around kickdown switch, if i floor it several times and mash pedal hard , it seems to then kick down,once it kicks down it pulls hard,i do have a hard2-3rd shift , and ive tried adjusting bowden cable, but cant get a happy medium still get a hard 2-3 shift 1-2 under regular driving is smooth, im suspecting maybe a weak spring in what ever controls 2-3 shifting, but for now i want to fix my intermittant 2-1 downshift first , then ill tackle 2-3 shift,ill soon be starting a c36 engine swap / build so i want my tranny in good shape
