I kind of feared that. I don't have much of a work area at the moment that this truck really fits in and I have heard that this transmission is around 300-400#. I am going to try changing the fluid in the transmission and hope for the best. Hopefully if fluid doesnt cure it a new clutch kit, slace, and master will. I suppose if this trans is shot I might swap out to the nv4500 since this nv5600 is an early model as far as I know. I can't find parts for the early models. It's just so odd that it's only upshifts.

I can get my NV5600 to shift if i am creative enough but it always wants to grind on upshifts. Notably worse between 1st and 2nd, 2nd and 3rd, 4th and 5th. 6th has never ground on me, and rarely a 3rd to 4th shift will. It never grinds on downshifts though. Also there is a rattling sound when idling second, usually when i am turning slow speed through a parking lot...but no rattling when accelerating while going straight. I am positive the sound is coming from the transmission. Any clues? :confused:

My tank looked the same, after 215k miles of mostly ULSD. :thumbsup My 1994 Dodge Dakota V6 gasoline pickup doesn't have any varnish in the tank. But then again the fuel gets used fairly quickly also. A lot of the varnish problems i have seen with cars is when they are stored for long periods of time. All that being said i did start adding the 2-stroke so hopefully there wont be a VP44 in my future lol.
