Royal Purple ok for 03 5-Speed? - Dodge Diesel

fitzydog · 05-29-2005, 08:01 AM

I understand you guys putting it in 6-speeds just wondering if it is good for 5-speed as well. Also did you guys change the transfer case with ATF-4 or use redline or something. I just purchased this 03 with 45k miles and don't have a manual or nothing. Also could someone include the amount of quarts in the tranny, I think 4? also the transfer case. Thanks guys and have a blessed day. Aaaron

Some folks use Amsoil atf, but not Royal Purple, that I am aware of...though I am a big fan of RP products. Dodge is pretty picky about atf, and the ATF+4 is only available from them...I buy it in gallon jugs on Ebay, and it works out to less than $3 per quart, I think...

I can't speak to the transfer case, since I have a 2wd, but I don't think ATF+4 is required there, not sure though

The NV5600 (6spd) uses a different oil than the NV4500 (5spd). Here's the recommended oils for the 5spd, 75W-90 Castrol Syntorque Synthetic,
Mopar Manual Transmission Lubricant (PN 4637579) and
GM Transmission oil (PN 12346191).

The OEM Castrol Syntorq LT is actually a 75W-85 GL4 lubricant. Available from standardtransmission.com for I believe $54 a gallon.

Redline offers full synthetic GL4 transmission lubes, and they recommend a 50/50 mix of their MTL/MT90 to get the desired viscosity for the NV4500.

A new player called Specialityformualtions.com also offers full synthetic GL4 manual transmission lubes, and their MTL-P is a direct replacement for Syntorq. It's $28.95 a gallon.

GL4 rated lubes usually contain 1/2 the sulfur and phosphorus found in GL5 lubes. This is done to preserve the yellow metals found in transmissions, and to allow proper synchro function. Some synthetic manufacturer's will say their GL-EVERYTHING lubes will work fine, but you may find them too slippery for proper synchro function. GL5's are intended for final drive axle differentials.

I use 4X4 quite a bit in winter plowing snow, and judged by the visible wear metals I've found in the drain ATF, I decided to search for something more robust. That's how I found Speciality Formulations, and now use their MTFGlide in the T-case. It's basically ATF, but with 5 times more anti-wear additives. It's also a full synthetic, and is $28.95 a gallon.

The NV4500 holds 4 quarts, and the NV241 standard holds 5 pints. The HD version holds 6.5 pints.
