600-910 Transfer Case Motor Compatible with Select Models

First off, the product quality seems good and it fixed my issue. 2005 suburban z71 with np8 transfer case and 4 button selector switch. My issue: service 4wd indicator and truck stuck in 4wd. Scan tool pulled c0321 code. Diagnosis: checked fuse (TREC) first. Then checked for corrosion/broken wires under fuse box in engine bay. Check for connections and corrosion behind knee plate under dash at TCCM. The TCCM is located on drivers side above emergency brake petal. Checked selector switch in dash with scan tool. Engaged/disengaged front axel with scan tool. Checked wiring/plug at encoder motor on t case. Verified 12v at the big orange wire in the connector. Then verified 5v at green wire. At this point I feel pretty confident it’s the encoder motor. Removal/Install: This is an easy job. Remove the skid plate below t case. Remove front driveshaft (it needs to go back the same way on the front diff so mark it before you take it apart). Unplug encoder motor. Remove the three bolts holding it on. Pull it out. IMPORTANT: The new encoder motor comes in the neutral position. The shaft on the t case has a key way on it. That key way needs to be facing straight down towards the ground which will put the t case in neutral. You need to put the vehicle transmission in neutral in order to turn the shaft on the t case!! Use wheel chocks please!! Once the transmission is in neutral, grab the shaft carefully with a pair of pliers and turn it so that the key way is facing down. Now you can install the encoder motor. Make sure you clean/reuse the gasket or, preferably, get a new gasket. There is a specific order to tighten/torque the bolts. Just google it. Clean/Reinstall everything else. Potential Problem: Here is what I wrote this review for bc I couldn’t find any information for the problem I encountered. When I turned my truck on, the lights on my selector switch flashed and then they all turned off and the t case wouldn’t respond. I scanned and pulled like 6 codes for the t case! Here is what I did. Check the plug to make sure it’s connected. Take both battery cables off the battery and touch them together for a few minutes. Reinstall and try again. I think the TCCM has to reset. Fired the truck back up, neutral light was illuminated on the switch and it shifted into all selections flawlessly. Hope this helps someone!

Fits like and works like OEM

I installed this motor correctly two times and neither time the 4high selection worked. 4 low and 2 high work fine but not 4 high. For the price and name this is a disgrace do not buy this one. Spend the money and get one from autozone etc.

I had been getting a Service 4wd alert on my 2005 Sierra Z71. I replaced the switch first, but that didn’t fix it. I tried to find the GM motor, but it seems that has been discontinued, which is surprising considering the number of vehicles that use this part. So I bought the Dorman. Side by side comparison, it seems pretty similar to the OEM part. I reused the gasket from the original after cleaning with brake cleaner, and I swapped the alignment bushing from the original using needle nose pliers. I have never done this job before, but it is not too difficult. I did it without completely removing the front drive shaft. I removed the retainers from the front end of the drive shaft so I could slide the shaft back and out of the yoke. This gave me enough room to get the middle bolt out of the old motor. The other two bolts came out with an impact. There are instructions and warnings on the new part to ensure that you don’t move the position of the motor by hand. If you can, you are supposed to put the transfer case in N by pressing the 2hi and 4lo buttons. Mine moved to N (I thought), but when I tried to put the new motor in, it wouldn’t align with the shaft on the transfer case. I grabbed the shaft with my fingers and turned it and it rotated a bit more and then had a very noticeable click as it found the actual neutral. Then the new motor went right in. I suspect this was the problem with my truck, it wasn’t fully in the position the motor thought it was in. Start to finish was probably about an hour, though I suspect it could be done faster now that I have an idea what I am doing. Hopefully this part will last and I won’t need to do it again.

I can't give 5 stars until I know the unit fixes the issues in the long run. Bought for my 2006 Yukon XL as I understood it was the part that I needed to resolve a myriad of issues I was seeing with the Yukon 4wd system. Specifically I got a 'Service 4 wheel drive" and "Stability system disabled" message from my car. Further the traction control system light lit up on my console and the lights on the 4wd switch were all off (no light indicating which drive system I was in and pushing buttons did nothing). All of these led me to an internet chase to find the issue, found that there is a Technical Service Bulletin for a contact failure within this encoder motor. I purchased and after installing in my Yukon the Service 4wd, and Stability system disabled resolved themselves, the traction control light turned off and the switch lights and function returned to normal. Best $150 fix I've had in a long time.

Saved me $2300 from the "new transfer case" that the shop told me I needed plus their labor. It's a small pain to replace, and I really wish they weren't so susceptible to water (drove through a puddle and fried the old one) but the new one has been on for 6 months with no issues now. Everything works as it should. You will have to drop the front driveshaft to replace it. There's a bolt that you really can't get to with the driveshaft in place. Do yourself a favor and skip the 1 hour fight of trying to reach that bolt without dropping the driveshaft like I did, and just pull it from the start lol

Fast shipping. Perfect fit works great.

El articulo corresponde a la descripción, Nuevo y al ser un producto dorman espero sea mejor calidad que los que son mas económicos. Me llegó el día de hoy (antes de lo esperado) y hoy mismo lo instale trabaja correctamente sin problemas. Corrigió la falla de mi Silverado 2005. NOTA: Viene en la posición Neutral, hay que poner el engrane del transfer en esa misma posición para poder instalarlo. ACTUALIZACIÓN: FUNCIONÓ SOLO 10 MESES, CURIOSAMENTE DAN SOLO 6 MESES DE GARANTÍA.
