Allison NSBU Replacement: The Easy Fix You Didn't Know About 

One of the best narratives, editing videos that i have seen in awhile

Explaining the reasons for switch replacement would be a good way to start the video. Common trouble codes and issues that point to malfunctioning gear selector switch. That's what I was hoping for. Thanks for video though.

I've watched several videos about this and this one I watched after I already figured it out but still this video by far is the best one I've seen! Quick, to the point, and very informative. Great work

Just changed mine out on my 04 chevy 2500hd, followed this video and the order as well. Best video on the tube.👍🏻 Thanks for sharing your experience with us. Great video!!!!!!!!

Great job best one out there. Second to none.👍🏻

I saved this to my cry it out list. Maybe it'll make me laugh maybe it'll make me cry idk but it hits my feels in a wierd way. I sent it to my wife, we recently seperated. She didn't respond.

Awsome. You guys rock! Thank you

Whats the purpose of replacing this part?

I can't thank you enough for this!

Some of the 2004 LLY Allison 1000 /M74 Vin2 only have one plug on the Park/Neutral Position Switch. If your scanner indicates various incorrect readings on Gear Commanded/ Gear Selected/ Current Gear/ Previous Gear such as; Park: Gear Commanded 0, Gear Selected 8, Current Gear 0, Previous gear 0, or Drive: Gear Commanded 1, Gear Selected 5, Current gear 1, Previous gear 1. Or Third Gear: Gear Commanded 1, Gear Selected 3, Current Gear 1, Previous gear 1. It may also make a whirring/ spinning noise for a couple of seconds with loss of intertia, and lunge for a second with loss of inertia. It may seem to do it more while cold and while hitting a rough spot in the road. You really should renew your spin on filter about every 3,000 miles, pan filter and all ATF every 10,000 miles.

Transmission in neutral but with the shift lever or down on the bottom?

I just put in a used 4l60e transfered my original switch didn't align it because I didn't know that they have to be aligned it only bolts on one way and the gear arm only goes one way back and fourth... My truck is jacked up in the rear and when I put it in reverse it last 3 seconds tires spin then stop .. new fluid new filter.. I was told that these switches nothing to do with how the transmission actually goes into gear.. but clearly it must ?? So my faulty or unaligned shifter switch could be the cause why my transmission won't go into gear because it's not getting ground or bad connection?? Weird how this lil peace plays a huge delicate roll.

I changed end check all the coneccions end still no power to trasmission to start the truck i have no light Underneath the letters Any idea

Did you move that front drive shaft?

Thanks dude, that was awesome!

nice tips

To bad you don’t mention the size of wrench or socket being used

I have shift inhibited and when it does work it goes into third and the clunks. I have replaced the switch Tcm valve body. And the internal harness and still nothing idk if this switch is bad again or if it’s the whole harness

Where did you get the part from ?

2004 3500 LB7 Allison 1000 5-speed with 270K and I am getting p0700 & p0875 codes, full fluid...No issues when cold until it warms up 110-psi... Any ideas or suggestions?

How do you change the 2006 6 speed Allison ? I haven't seen any videos on it.

Great video. mine seems to be leaking from the shaft. any suggestions?

Would this fix a no reverse? 04.5 lly? If I clear codes. Truck will go in reverse.

Does the one for the 2005 come in neutral ? It doesn’t have that retainer clip on it. Is it supposed to?
