If that sensor goes bad will it cause the truck to shift funny and for the OD light to flash?
Is limp mode what my trans is doing now with the crappy shifts and flashing od light?Yes you will have to adjust the new tps. Simpley remove but watch and feel how it comes off the drive tab on the end of the throttl shaft. Install the new one the same way twisting it back in place. Once its installed tight to the bracket snug down the two adjusting bolts but not so tight that you can't move the switch bracket to make an adjustment. Now turn the ignition switch on but engine off. If your doing this on a cold engine you should remove the fast idle solenoid wire to make sure the throttle setting is at idle. Now that its done use the center wire on the switch plug for voltage reading. At idle setting key on but engine off the voltage is best at 1.1 or 1.2 volts. Its really a personal choice. The voltage factory oem setting is .96 to 1.2 volts. Once its set and the bracket is tight check it again. Now sweep the throttle wide open. Make sure you don't see 5 volts. At 5 volts the computer that controls the E4OD trans shuts down on over voltage and you go into limp home mode. Its very harsh to run the rig like that and it will kill the trans quickly. Its disegn is to "get you off the road safely".. Not limp home a thousand miles or so. I will bet the wide open voltage will be around 3.4 to 3.9 volts.. Maybe even low 4s. Please post back what you get for setting at the voltage you choose. Someone is here to help no matter what time of day or nite.
