I'm curious how you went about getting 7e8 and 7ea. what was used to get codes like that.


when you say you start the engine, shift into gear but the car doesn't go. is it possible the shift cable broke and you're not. actually shifting the transmission into. drive?

I used this thing to check the codes and that’s what it gave me. It’s kind of weird because when I drive it it’ll drive and all of a sudden it’ll throw these codes something like traction control or something about stability and then it’ll say power reduce. So I’ll cut it off and hook the equipment up and check the codes and that’s what it give me. It cranks up fine goes into gear fine but when I try to mash the gas it’s not doing anything

It have 240,000 miles

so what he is asking is does the shifter feel normal and it's clicking from p/r/n/d/l ? or is the shifter all floppy like it's not connected to anything?
if it is all floppy then sometimes the lever under truck comes loose from age

I can’t say anything is broke because like I said it just started doing this yesterday and it doesn’t do it everytime I drive it , very weird .

No it doesn’t feel floppy it feel normal no jerking or anything

so it's not the shifter, sounds like a transmission shop needs to take a look at it.
SOMETIMES, if you are lucky the throttle body can cause those errors and if that is the case it's a lot cheaper and easier to fix.

Oh okay , I just think it’s weird because it never made any noise just started doing this out of nowhere.

if you can get the Pxxx codes that might be helpful, the 7e8/7e9 are very generic, those are not normal gm codes

Okay I’m a try in the morning and see what I can get .

I do agree it sounds like it could be the throttle body but I'm not fully understanding what it's doing. I thought it wasn't drivable at all. like put in gear, hit the gas rpms go up truck doesn't go anything.

can you take a pic of what you're using to read codes? I only ask cause I've even see a code like that in my life from any scanner. got me curious.


so the truck drives some times but then dash lights come on, says reduced power. you hit the gas but nothing happens? it doesn't rev up the engine or anything, just like the throttle pedal is dead? that sounds throttle body to me. but total shot in the dark without some fault codes that show something we can look up. like said about the codes usually start with a P like P0300 is misfire code. things like that. I don't know the throttle body code off hand, but I'm sure there's one for it.
