I don’t want to provide you with any undesirable news, but it really Appears similar to what I just went by… and it absolutely was the Transfer Situation that wanted assistance… poorly. My Blazer in all probability only has ten-15 hours on the 4WD method, nonetheless the “forks†In the TC have been terribly worn and enabling my gears to float, which made indicators such as you describe (among the Many others).
If you end up picking to begin a completely new Discussion board subject, you could attach files to the post. If you choose to upload an image, it will produce a new topic inside my site (which I will then transfer to be bundled inside of your original put up).
Unplugging the TCCM isn’t an awesome thought mainly because it genuinely doesn’t attain nearly anything. In case you are trapped in 4WD (which it seems like you might be), unplugging the TCCM will never get you back again to 2WD. On the other hand, I don’t desire to let you know to carry on to drive the motor vehicle without realizing further more information — maybe you have a challenge With all the gears/forks in the TC which can not allow the encoder motor to physically swap modes — not surprisingly, driving the auto During this issue would only result in greater damage.
I am tremendously indebted to you personally. My new spouse’s 2000 Blazer shed her 4wd a calendar year ago. SHe found your Web page regarding the TCCM module corrosion, printed off the knowledge and her mechanic fixed it. He was also amazed.
No issue in the least… that was my sole intention… to aid Other individuals with a similar difficulty (and conserve a ton of money too!).
What it feels like, to me, is usually a wiring problem — most certainly among the encoder and also the TCCM (underneath the kick panel). Have you ever pulled the kick panel and experienced a look at the TCCM wiring (as pictured int he initial put up of this site entry)?

The motorists aspect, front axle is often engaged Along with the front diff — the passengers side, front axle is managed from the vacuum change, actuator and cable. The vacuum change is a typical component to fail. There's two challenges trying to Get the motor vehicle into 4wd that has a failed vacuum change;
What it seems like is you might have an encoder motor dilemma — This can be the motor within the side in the Transfer Circumstance that controls the shifting of the various “modes†(2Hi, 4Hi & 4Lo).
Okay, the module location — I can’t truly describe it much better than I did for the final remark poster, but just in case you missed that part… sit in the passenger seat — swing your right foot back and forth even though trying to keep your heel on the ground — you’ll strike your left foot A method, as well as plastic panel where the module is located the opposite way. Some more mature pickup trucks had a “vent†pull take care of Found there, if that helps! As for your chilly causing the challenge — may be. That’s the challenge — there are numerous things it could be. There exists, what is known as an “encoder moduleâ€, about the aspect of your transfer scenario that controls which mode you will be in (two, 4HI, 4LO) — if drinking water acquired in there and froze, it may be preventing the encoder from altering modes.
Many thanks to the instructions on uploading pictures. Is it possible to you should insert this to my primary write-up. I’d definitely like some assistance on this.
This is certainly my 2nd time bringing a car or truck to Euro Collision & this time I labored with Albi. He was wonderful - really pleasant & beneficial throughout the 6 months my auto was getting worked on & even in the months soon after I acquired my vehicle back. In any case their labor, my car or truck looks fresh. Will certainly return!
Hmmm… it’s hard to say — it could be as simple as the encoder motor sign strains staying corroded/ruined (check the schematics in the very first put up), or it may be the transfer situation alone. In the event the lights get the job done as they should, then this tells me the 4WD method is engaging, accomplishing what it must. I believe the transfer scenario is not really shifting adequately. As I stated into a poster earlier mentioned, it might be time to acquire your transfer situation checked by a tranny store.
Hmmm… Try Here could possibly be a number of factors. Very first, if you can find into 4Lo, things almost certainly aren’t as undesirable as they seem — this, fundamentally, lets you know that the factors while in the process are Performing.
