The th350 tranny was not stock to the car, rather it was a 700r4. Either a new kickdown cable is needed for the conversion or adjustments made to the existing cable.
There is no cable. Just a slave at the motor. No adjustments. Hyd. system
To adjust the kick down cable there is a clip that u remove and adjust the sheth lenght. if you cant get enough adjustment from that they sell replacement cables that are adjustable. The technical name is Detent cable
Hold your finger down on the app until it shakes, then ckick on the X
To adjust the cable just go 1/2 way down the clutch cable and pull the rubber over the adjuster. loosten the lock nut and adjust the cable so there is about 1/8" free play at the handle.
This is not a "kick-down" cable per my tranny mechanic. This cable goes to a transmission fluid pressure valve and will burn up your transmission if not changed immediately....
Loosen the clamp bolts on the cable. If it is shifting down to a lower gear when the throttle is at max it is all right. If it is shifting down too early, lengthen the cable adjustment. If it is shifting down too late or not at all shorten the cable adjustment.
if the clutch is cable yes there is an adjuster down beside the transmission follow clutch cable
there is an Allen screw and a nut on the throttle cable you loosen the nut and the screw and adjust it to make it idle up or down.
Shorten the kickdown cable to make the transmission kick down into a lower gear sooner. Lengthen the cable to make the transmission shift down later or at a lower power setting.
That happen to my 4runner you need to rebuild the tranny or buy a new one cost me $1800. sorry
To to adjust the throttle cable, first take off the air cleaner. Hold down the metal adjusting tab that is at the end of the cable.There is a sliding piece at the end of the cable, move it against the end. Let go of the adjusting tab then move the cable to the end.
