tranny noise
 

Sooo I was heading down the freeway doing 60mph towing M105A2 trailer I just picked up off craigs list when I start to hear a kinda bearing noise, not sure where its coming from so I pull over and start to check things out, not leaking any fluids that I can see no obviouse drips so I wait until traffic is clear I take off on the shoulder of the freeway in 2nd gear and noise is still there go to 3rd and it gets a little louder so I called a wrecker got towed home and started looking for the noise I found that my trans was blowing oil out the breather tube I think, there is a rubber hose that comes from what looks like the top of trans and is secured to about a 4" hard line bolted to the back of engine tranny oil blown all over trans and exhaust, pull filler plug cannot touch oil , pop right side pto cover and drain a little more than a quart of oil out 3 quarts short and oil is got glitter in it and fine stuff in the bottom of trans, not sure what to do next just replace nv4500, upgrade to a 6 speed or try to rebuild this myself, what is everyones opinion, are these hard to rebuild, thanks for any imput Eddie.

it's not to bad. the fifth gear jam nut is a booger.hopefully you haven't welded it on. i drilled 2 holes in mine then broke it with a chisel.somebody had beat it on with a punch. i wanted to see how it worked since i had never been into one, so i moved the shifter with the input shaft out and successfully launch a spring and dog out the front.so i took it apart and put it back together, never having been into one before.

My understanding is there real simple, of course I do 13,18speeds so , these little ones are a sinch to pull and redo ...
