P0717 code
 

Hello ,I really want to thank everyone for helping me getting this thing running again. I have a 2007 hummer h3 and I recently got p0717, shifting acting up. I looked up the code it’s the transmission input speed sensor, I found the right part at a local store. I made a research and some people said might be shorten or dirty because of the elements etc. I am trying to find it and I can’t see to find it. Online they say it’s in the passenger side next to the transmission put can’t find anything!! Can you help me find it or send me pics so I can check out?

thank you

Is there a chance that something got lose inside the pan because the shop dropped the pan not that long ago and did transmission fluid and I noticed that plug plugs just above the pan so I was wondering if something got lose is that possible ?

Doubtful, but anything is possible, however you need to drop the pan to check(I have in the past found pinched wiring between the pan and housing causing an issue). In the meantime test the signal to the pins as I posted above.

Here's a pic of the harness inside:

Hummerz PLZ help. yesterday I the car stopped shifting gears it run very sluggish, not shifting, and also have more codes. I replaced the solenoids A and B and torque convertor and also the down shift 3-2 and it still does it. I checked the wires and I haven't seen. anything
I have all those codes
P0976
P0717
P0787
P0973
P2769
P2764

I also made another thread about that :( is my transmission dying?

It still points to the ISS, you NEED to check with multi meter, without the p0717 there is a TSB:

I’ll try that and let you know soon thank you

I just read your post again, when did you replace the torque converter?

I replaced the torque converter selenoid when I changed the shift selenoids

TCC PWM failure usually sets p1860 or p1870. Your codes point to a signal loss(wiring/connectors)

So like a short somewhere? I haven’t done the steps u told me yet but I am doing them
tonight

Yes, and check the connectors since you caused more codes after you threw parts at it!

You started with P0717 ISS Failure(most likely shorted wiring inside the trans)

after you pulled the connector to the trans and threw parts at it, you now have:
P0976 Shift Solenoid B Control Circuit Low
P0787 Shift/Timing Solenoid A Low
P0973 Shift Solenoid A Control Circuit Low
P2769 Torque Converter Clutch Circuit Low
P2764 Torque Converter Clutch Pressure Control Solenoid Control Circuit Low

Did you perform the 1st step in any electrical component replacement: Disconnect battery?
Did you clear all codes and recheck?
Did you make sure all connectors were clean and secure?

At this point, my advice to you is to take it to a repair shop before you cause any more issues.

if you left the battery connected those might just be stored codes from when you disconnected the parts. if you erase them and they come back then it has issues as Hummers mentioned.

after hours of searching I found the wire harness under the transmission panel is pinched badly. I contacted the dealershiop
they told me its this part number gm part number 24298347. but its like 230 bucks..and its on back order.

any aftermarket harness I can find for cheaper?

thanks

is that the same harness you sent me a pic of in this post???? is that the same part? if yes where can I get it from and what would be the replacement part number instead of the oem

it might be better to just repair the one you have properly.

The shop said the pinch is too deep not recommended to repair but I just want to know is it that rostra wire harness that they are talking about ?

google the part number you posted. there are a bunch of online gm parts distributors that are selling it much cheaper then $230. GMwholesale has it listed for $141.83

Yes i I saw that but they don’t have a pic. I found transmission harness for 57 bucks aftermarket that have just like the pic hummerz posted. Everyone who have it cheaper for 137 or 141 is out of stock because it’s on back order

Any tech with proper knowledge knows you can repair a wiring harness. I would pull the pins on each end of the damaged wire, and install a new wire with new pins.

Call for more information on a replacement harness(note you have a 20pin connector):

He wont replace it but I found one that is 57 bucks it’s cheaper to replace than repair . But that’s how the wire harness look like and found it way cheaper , can I replace that my self or does it require special tool or way? Also they mentioned they have to relearn it?

"The shop" damaged your wiring harness and "the shop" will not replace the harness?
Btw, My '07 transmission shifts great and never had any pinched wires.
You are all over the place with your posts, I need another beer!

You have a 20pin connector(you posted a picture above), the "57bucks" is a 13pin.. Call the number I posted above and make sure you get the proper connector or it's useless. :rolleyes:

Yes thank you , I got one from rockauto that is it for the 07 hummer h3 that have 20 pin connector I believe cus they said that fit for the 07 but ill
dpuble check

That is only an external repair connector! :eek:

That's the right harness..

24234121 replaced by 24298347

Btw, Clear codes and disconnect battery before you replace and make sure all connectors are greased and secured.
