I used to have the TPS one , but have since lost it and just need to know if the others have one and how?
thank you so much

 

After deciphering your sketchy cryptic question.... if you are asking whether the items in your thread title need some relearn procedure vs simply bolt in..... the answer is they are plug and play, no relearns.

 

I apologize for my hard to understand previous post, just a single mom trying to figure out how the heck to keep a Hummer running, and my explaining is not always the best. i was mostly wanting to know if i should be concerned that their no sounds of 4H Lock engaging when the button is pressed, but the normal clicking going between the other buttons. the relearns I should have researched a little more before bothering the forum with stupid run on stuff. I found a couple relearn procedures and ordered a TCCM. maybe that will help.
Thank you for ur ever so polite response and ur time.

 

Maybe take a look at the problems caused by a failed plastic transfer case shift fork. Lots of threads here about it.
