1992 Ford F-150 Repair Question
92 ford f150 code 634?
oh yeah it's a 302 and it has a trans kickdown cable i think. has 2 cables 1 is cruise. hitting gas does increse shift times somewhat but still shifts harder than should.
adjust the tps to .5 to .75 volts at closed throttle.

did not check voltage yet the tps is not adjustable as far as i can tell. but unplugged IAC and idle went down. while this helped with gear engagement 'bump' it did not change trans bang shifting at low throttle. still got code 634. also trans has NO kickdown cable.
brother had replaced TPS and vehicle drove accelerated but when i tested TPS for operation it did not change readings when he stepped on throttle. i watched some youtube vids about testing and saw readings change with throttle change. his is says at .8 if i remember correctly. i went to store and bench tested a unit just to make sure i did it right and store part worked fine changing readings. he still has unplugged iac for idle and now starts in 2 to avoid hard shifts.
