Help,
I've drained all the fluid out of the transmission, picked up Mopar ATF+4 at the dodge dealer last week. I told him what I had and that's what he gave me. But the plate on the PTO cover says to ONLY Use TEXACO STF 1874.
Is the Mopar ATF+4 fine, or am I stuck until I find something else
THanks

I say take it back. Its the wrong stuff and your parts guy is on crack.

The specs for the fluid you are supposed to use is found here:

Many people have used Redline MTL, Royal Purple, Amsoil with great success.

 

I had Redline MTL in my 2001 for 50+k miles... absolutely no problems at all.

 

I've been using ATF+4 in mine since I've had it and have never had a problem out of my 6 speed. ATF+4 is what it is supposed to have in it. Any dealer will tell you that. Have you looked to see if TEXACO STF 1874 is the equivalent to ATF+4? TEXACO STF 1874 is paraffin based oil. It doesn't flow as well in the cold as the synthetic ATF+4. That means in cold weather your 6 speed will not want to shift as well until it warms up. My 06 has over 180k on it using only ATF+4. With today’s close mess tranny's they need low viscosity oil. Either will work though. The TEXACO STF 1874 is what was used prior to ATF+4 in the 5 speeds. I could be wrong on that but I'm sure someone will look it up and correct me if I am.

I just installed a used nv5600 and was wondering if there is an oil that helps the sychronizers grab, mine scraps a little if you are not easy whith it.

 

yeah, ATF, Automatic Transmission Fluid

ATF 4 goes in the autos and tcases.
look in your owners manual under specifications and capacities. I will tell you gear oil GL5 synthetic.

 

ATF+4 goes in the new G56 transmission. You should hav ethe NV5600 six speed. Do not put ATF+4 in the NV5600! You will roast the transmission. Check your owners manual for the proper fluid.

 

Mark, your sig says you have an auto....

 

That's funny, I have to admit it....

 

Dr. Evil
My signature states I have 2 trucks a 2005 with a 48re and the 2006 does have a G56 in wich does takes ATF4 but it doesn't state what is in the 06 though but it will in just a few.

Totally incorrect. The 5 speeds (NV4500) use Castrol Syntorq, which is no where near ATF.

 

See I stand corrected

 

Do not use a GL5 synthetic. GL5 is formulated for axles and has sulphur-bearing additives that will corrode the yellow metal used in manual transmission synchronizers. GL5 will effectively reduce synchronizer life in the NV5600 by about half.

Use a GL4 synthetic in the NV5600. The recommended fluids, Redline MTL, Texaco 1874, etc., are all rated GL4. (Along the same lines, don't use these GL4 fluids in your axles....)

 

and i stand corrected as well. gl5 is for the axles, sorry.
just throw redline mtl in it and be done.
