Im not seeing a rear abs sensor at all.

Where are you looking? Parts catalog or are you looking at your truck?

I read that some do not have a rear abs sensor, it said the speed sensor in tailshaft acts as one for the rear, but yea, i have my old rear end out of the truck and it doesnt have an abs sensor

Look for the VSS on tcase or trans. Losing Speedo and in limp home a bad indicator. I'm not sure what your truck has equipped wise. Some are internal. Know a transmission guy?

There would be two, mounted with a 10mm bolt underneath each axle near the bearings with cables going to them. I thought all the NBS had them. My 02 Yukon Denali has them. If you had access to a Tech2 you could look to see what your truck used, probably the VSS in the trans like mentioned.

I may send the abs module off and have it redone but i dont think that would cause the trans shift issue..idk, ive checked everything possible, except the codes. I really appreciat yalls help..

If the speed sensors have issues it can cause all kinds of trouble including going into limp mode where the trans won’t shift. I’m not sure if it does that for just ABS issues but the speed sensors will cause ABS issues so it’s all tied together.

Definately Scan It! Even if you take it to trans shop. Been guessing for a few days now. If you can't tell if you have rear ABS sensors, maybe its time to put it in capable hands before you destroy trans.
