Diesel or gas engine?
wow no diving symptoms stated, does it shift all gears and drive perfectly,(i bet not with TSS2 dead)
507 means idle speed out of control
2767 means input speed sensor reads wrong.
sensor 2 dead. means (no signal at all)
that means clean it or replace it.
did you clear codes first, drive and be sure they are real. (comes back)
2767(lost power to sensor?) check all fuses first?
NAG1 (trans only)
(T72) SENSOR SUPPLY VOLTAGE CIRCUIT OPEN ()fuses)
(T71) INPUT SPEED SENSOR 2 (N3) SIGNAL CIRCUIT OPEN
(T71) SPEED SENSOR 2 (N3) SIGNAL CIRCUIT SHORT TO ANOTHER CIRCUIT
(T13) SENSOR GROUND CIRCUIT OPEN
(T13) SENSOR GROUND CIRCUIT SHORT TO ANOTHER CIRCUIT
(T71) SPEED SENSOR 2 (N3) SIGNAL CIRCUIT SHORT TO GROUND
(T13) SENSOR GROUND CIRCUIT SHORT TO GROUND
INPUT SPEED SENSOR 2 (N3)

P0507
read page c9 - p547 yet it answers all questions. all 5 possible.
the fsm, free and posted here 100s of times.
my guess vacuum leaks or idle speed control valve stuck open.

pdf page 3949, is bingo. as is all pages on 2767.
chapter 9.
the sensors can be remove , clean the crud from tip
and try again.
in most cases of all speed sensors.
Code p 0507 refers to idle speed control (ISC) system rpm higher than expected==causes -wiring--ISC actuator/IAC valve --throttle motor -- throttle valve tight / sticking---ECM
it als o refers to idle air control(IAC) system--circuit low===causes --wiring short to ground --IAC valve ---ECM
code p 2767 refers to transmission input shaft speed sensor/turbine shaft speed (TSS) sensor B---no signal===causes --wiring---transmission input shaft speed sensor /TSS sensor
