Well I did it I was able to order the NSBU switch for my 01 DMax. What else is going to go wrong?:eek:
The four wheel drive transfer case went on the truck last month the NSBU switch this month, fuel pressure regulator is growling oh yes idler pulley went too!! Been a good two months.
Well anyway you were all right NSBU was the problem started loosing gears no reverse always went to third gear. Put the new one in Kudos to eric! now she runs like a champ. Broke open the old NSBU well we had to because the stupid plugs wouldn't come out the grease had turned to what look like epoxy!!!:eek: What Junk!

Well thanks for all the help from everyone!!!!:grd:

i have 01 also, replaced nsbu switch at 70,000 and its going out at 125,000
had to replace cruz switch wire broke and it caught on fire. change u-joints ball joints and front wheel bearings. everything else seems ok.

Yeah, there's no denying that the old black NSBU switches were junk. But you shouldn't have the same problem with the tan switch.

Do the dealers stock the new NSBU switch? Some of my gear selector lights don't light up, and after reading through a couple threads, sounds like it's the switch. Where is it, and what's the details for the install? Thanks!

Yes most dealers stock when mine went out, i had a new one installed in an hour of bringing it up to dealer

Ryno,

If your truck is still under the emission warranty (100k if I remember right) you can have the dealership do it for free. If you want to do it yourself your best option is to buy it at a Detroit Diesel-Allison distributor (you can get locations from the Allison Transmission web site) as it will be cheaper. While there ask for the Service Information Letter 32-1K2K-01, which has the installation instructions.

Good luck!

I saved like a $100 from what the dealer was going to charge me.
hardest part was crawling under the truck.

I talked to the dealer today. I have an 8.1, I'm SOL with 60k on my 02. I did go to Allison for the switch...ALOT cheaper. I'm doing it tomorrow, looks pretty simple. Any tips/ tricks?

Don't remeber anything special, make sure you take your time with the plugs. and use dielectric grease...etc. I am sureone else will chime in.
