I will report back after I crawl under there. Since everyone seems to have the TCCM issue, it is probably a matter of time before this issue becomes common too.

 

You saw it as, I was maybe a troll?

 

also, to ncdurango, I don't recall exactly how I determined it was in 2wd. I think it shifted into 4hi in 1 direction, 4lo in the other, 2wd was somewhere in the middle. even if your motor shifts the gears, it's a 2 part unit. the range sensor part could be bad. ps. my symptoms were a little different. I could go on & on but I just got home with 2 tccm units. paid 40 for one & 50 for the other. fingers crossed!

 

to ncdurango, being as you are going to test your transfer case motor & range sensor, I assume you are smarter than I and you will probably not bang on your driveshaft. I am now looking for a replacement or rebuilder. I think it was going bad any way but I sped up the process. I would suggest removing & replacing the u-joint if it doesn't collapse properly. good luck.

 

You got it! But I was wrong, you're an *** instead.


BTW<----3 posts in a row isn't going to get you anything. Just edit your post if nobody has responded.

 

Well, I think I am happy to report my 4wd Hi now works. The reason i am not sure is because i don't know what happended to make the change. I drove it up on ramps, unplugged the motor, put a multi-meter on the leads, and had my dad move the switch. when he did he said the light was blinking (it didn't do this before). I plugged it back in and heard the motor switch to 4Hi. the light still blinks when switched to 4lo. I don't know if the TCCM's have to re-learn anything like the ECU/DME's do when unpowered for a long period of time. I wonder if derango01 is right that the mode sensor is ***'d.

I will continue to monitor it over the next few weeks. 4hi is of course what i need for the wintery mix but i would like to go wheelin' with my buddy this spring if i can get 4lo working. The wheelin' idea is new to me as i am a track guy by nature. But went to WVU and many friends had some fun rigs (they never let me drive).

 

in order to get 4lo you have to put the transmission in nuetral and it prefers to be rolling slowly while making the switch, glad its working for ya again

 

Sounds like a bad connection to me.


Also, roll to engage the 4low as Sharps states.

 

oh, i will try it and report back. fingers crossed!

 

It all works as it should! I thought Park and Neutral would have the same effect but it doesn't. It must be in Neutral like you guys said. We got 7 inches of snow during Christmas so I got to use it and it performed as designed. I guess it was a loose or bad connection to the motor. Thank you guys for all of your input!
