Questions & Answers

How does this product work if you have a slight leak in your transfer case?

Using this method, a leak can be prevented from occurring due to sharp edges of the OEM pump chipping away at the casing. Put it where you can find It needs to be fixed.

If you remove just the rear housing, does the transfer case need to be removed or can you do it without it? I appreciate it! ?

It's not possible to install after the transfer case has been removed.

According to the packaging, it is compatible with the Np136. Are you able to use this with a NP236?

is not listed in the description then there definitely is a difference. I would contact merchant automotive and ask them whether this part will work for the 236 you are asking about since it is intended for

Is there a cost estimate for installing this from a transmission shop?

The price would probably be $500 or so. A spare transfer case was purchased and the parts were installed After that, I paid them $300 to install it at a transmission shop.

I enjoyed this piece a lot

5/5

It's a 2003 Chevrolet Silverado 1500HD 4x4, and I've owned it since I bought it Following a youtube video of the process, I bought this kit and took it to my mechanic for installation.

Silverado z71 from 2004

5/5

This is a great program and is very easy to To install this ring, you will need two wide jaw snap ring pliers, a flat head screwdriver, and an allen wrench with torq #10. My father did it himself to save money since I am not mechanically inclined. There are BEEFY tabs on this adapter as opposed to knife edges on You've got to go to the junk yard In an older case with only 90,000 miles on it, the pump was also scratched. Don't let fear get the better of you. Invest in peace of mind now.

THERE IS A FIX FOR THIS

5/5

If you are looking at this product as a preventative measure or because the damage has already been done to the tail stock on your transfer case, NP261/NP263, I am confident that this is the best available on the market, high-quality, perfect fit, problem solved! I believe there should be a class action lawsuit brought against GM for the design flaw regarding the pump/case fitment issues. HAD KNOWN ABOUT THIS BEFORE IT WAS TOO LATE, I would have bought it, it is worth the investment in the long run. SO.

This is an excellent product

5/5

Pump rub was not as bad for me as it was for others. To check if there was an issue with my NP246 from my 07 Suburban, I removed the engine, as I was getting the GM clonk (and still do). As 185k wore on the transfer case, I thought something would have worn out. Nothing like that has worked. I did, however, learn that a TSB problem was associated with these transfer cases while I was there. It was back in the pump housing after I replaced the housing. I love the quality of this product and it fits If you don't need one, you don't need one.

This is a great tool for transferring cases! In my search to find a real fix, I came across this video on YouTube after getting my phone rebuilt and still having the same issue a year later

5/5

As for me, I have used it on transfer case #3 and believe it will be the last.
There are a lot of places that say a rebuilt will take care of it or they use a thicker case instead. Those are just words they use to reassure you, because the system should last 150k miles. A nice gesture, but 17k later another leaking case, if they had put this in I may still be on case number Now that I have the PDF, I am very happy!.

This kit will be good to me if it does that

5/5

The ECSB code for the 2004 GMC Sierra is We had the dealership install the plate on a 3 Vortec with an NP8 RPO. As far as the technician was concerned, everything went together without a hitch. I paid for the labor to remove and partially tear down the transfer case, but if the transmission does not blow, then I will be satisfied with the.

This is the second of these kits I have installed from MA

5/5

This is the second of these kits I have installed from MA. It ended up being a big problem later on because there was a tiny amount of rub on the case. There were no problems with the truck during the 50,000-mile run. As soon as the case is removed from the truck, the installation isn't difficult at all. In the second and third cases, the 2500HD developed a leak by the time they were installed. Half the money I spent on the case was to fix the damage that had already been done, and I am now confident that this case won't have "pump rub" issues.

I needed a replacement for my transfer case that began showing rub wear on its case

5/5

The process was straightforward, and I got a great quality replacement over stock. The unit was replaced in a matter of hours with this one and all the seals were changed since it was The amount of RTV they give you is generous, and I had to repaint it three times because I could not fit the cone snap ring.
