New NPR and NQR Transmission Fluid Requirements

From late 2007 and up, NQR and NPR Imported Trucks come with a new type of automatic transmission that requires an inexpensive silicone-based transmission fluid.

It is a must that you use a silicone-based fluid such as Isuzu SCS Automatic Transmission Fluid — Isuzu part # 2-90531-200-0.  If you don’t use the proper fluid, it will burn up your transmission in a matter of a day.  You cannot use regular automatic transmission fluid or a petroleum based fluid in the NQR or NPR trucks built after late 2007.  This fluid is not expensive at all, it costs about the same as Dexron.

We have already seen what using the wrong fluid will do to the transmission. We have had several transmissions that were burnt-up under warranty because they had used regular Dexron/Mercon fluid.

Which models require the new fluid?

Isuzu started producing this transmisison in mid-2007, some ’07 models use the fluid and some don’t.  Anything later than ’07 will require the new transmission fluid and late model 2007 trucks will require the new transmission fluid as well.

How to Identify Your 2007 Model NPR or NQR

Late model 2007 trucks will require the new silicone-based fluid such as Isuzu SCS Automatic Transmission Fluid — Isuzu part # 2-90531-200-0.  If you have a 2007 model Isuzu NPR or NQR, you can easily identify if you have the old style ’07 or the new style ’07, by the door handle.  It’s that easy.

If you have the new style – a late ’07 (bottom photo) – you need to use the silicone-based fluid such as Isuzu SCS Automatic Transmission Fluid — Isuzu part # 2-90531-200-0.  It is very important not to mix the fluids, know which one you need.

Fluid Requirements on Dip Stick

Also, you can identify what fluid you need by looking at the top of the disptick tube located on the driver’s side of the truck aftery oyou’ve flipped the cab forward .

The dispstick tube will be located right where the motor and transmission bolt together just behind where the starter bolts to the transmission. At the top of that tube, the small print will tell you what kind of fluid your truck requires, an SCS fluid or an ATM fluid.  The SCS is the new silicone-based one.

We realize that the trucks that we sell parts for are critical for your business. We want to do everything we can to help you succeed and to keep your Isuzu NPR box trucks, Mitsubishi Fuso, Hino and UD mid-range box trucks, Chevy W3500, W4500, W5500 trucks and any other vehicles in your fleet running.
