Transmission codes code P0717 p0700 Chevrolet GMC fixed easy

2007-2014 GMC Chevrolet Chevy Silverado Tahoe Yukon Sierra avalanche denali Escalade Cadillac
If you have those 2 codes p0717 p0700 and tried replacing the speed sensor along with tcm transmission module due to hard shifts shifting 1 and 2 gear try changing your alternator they have diodes regulators that go bad and causes transmission TCM malfunctions..if it works like my video share it thanks

Thank you thank you thank you for making this video. I had the same codes, I watched your video and had the alternator tested. When they tested it they found out that my battery was bad even though it still started the truck and there were no signs of it being bad. I replaced my battery and I have no more codes an no more transmission slipping from first to second gear. I would have never thought that a bad battery or alternator would have caused this unless I saw your video. You rock!

fixed my truck after days of trying to fiqure it out .thanks so much for the great information

Thank you man my 07 silverado just threw the same codes. I have the same symptons of shifting hard in first to 2nd. I checked the amps that the alternator was dishing out and it was all over the place aometimes as high as 15amps. My mechanic advised me to change it because something is going on with it he said it shouldnt be overcharging like that. So im going to test your theory for $200 bucks minus a $34 core charge for the 145amp alternator im replacing and hopefully it solves my issue

Very logical speech
Since these cars depend on electrical signals
You are right
thank you very much

Def going to look into this tommorow,
my tbss is throwing the same codes. I blew a transmisson replaced it with a rebuilt 4l70e changed the ISS nothing. This has to be the culprit of my problem

I have a 2007 Chevy Tahoe. Symptom on it is rpm doesn’t shift it just idles high and it doesn’t go into gear. Mph only at 40. Gonna try the alternator

[davidtrisha]

My 2008 trailblazer ss has the same codes. I might just give it a try

[billy-sxwx]

I did this as a last ditch’s effort to avoid pulling the trans. Didn’t work. The alternator was warrenty so no loss there. Ended up pulling the transmission. Speed sensor fixed the issue. 😩😩😩

[stevezuech]

The speed sensor made your car better though ?

[angelitolozano]

I have a 2008 chevy silverado lt 1500 5.3 extended cab. I have a code U0100 it doesn't have no power what so ever at all does not change gears when I'm driving. Need help what could it be?

[htown]

Was it shifting hard (like jerking/snap your head back) from 1st going into 2nd?
Speed sensor did nothing for me.
Can you provide the link for the video you mentioned that helped you out please.

[juniorgarcia]

[asauce]

I have codes P0716 and P0717. I replaced alternator and this did not fix the hard shift. My next step is to replace the speed sensor

[sigurdurkjartansson]

[andresv]

Do you know what waa your voltage for the battery or the alternator

[edwardtasi]

I have an 07 colorado P0717 Shifting hard 1st to 2nd gear then it's fine.Some people are saying speed sensor is internal transmission and others are saying it's bolted outside the transmission?

[orlandoaguilera]
