nv5600. need help!
 

i have the nv5600. ive had a southbend dual disc 3250 in the truck for prob 4 months. i tow a boat every other day and i sled pull every other weekend. i seriously doubt i burned my clutch up. but im not sure. the clutch i believe is rated 500 h.p and 1000 ft'lbs witch im prob 500 h.p or more. i recently was at a sled pull and on my last pull it felt like i spun the clutch. i was told that my hydros went out. witch dosent make sence to me. i cant put the transmission in any gear 1,2,3,4,5,6 or rev. while the engine is running. but if i put it in 3rd gear with the truck off and start it i can relese the clutch and float the gears. another reason why i doubt the clutch is toast is i did a 3rd gear powerbrake today and the clutch held all the power and smoked 37 inch tires? im no expert on transmissions but i think my syncros are messed up or something. any info or help would be great.

sorry if spelling is wrong im in a hurry. :c:

Sounds like Hydros

i just installed southbend's hydro kit.? im lost with this problem :s:

When you say you cant get it in gear does it grind? or does it just not want to go into the gears?

it dosent grind it just dosent go in.

Synchro's sounds like to me. The 4500's have that problem too. Sometimes trying different synchro mesh fluids help. I am using royal purple right now but not really impressed with it. The syncros on the 4500 have a bronze sync ring with some friction material bonded to the inner tapered cone, when the friction material gets worn down it causes grinding gears between shifts. I would try changing to a different fluid first and examine the fluid that you drain out for metal and debris.

i just changed the tranny fluid about a month ago and the guy at a local parts store said you have to run mopar oil. it was like 25$ a quart.? so im not to sure i have a feeling something is stuck like the trowout berring isnt moving all the way back to let the clutch fully disengage. tommaro i will find out. took the day off work and im gonna drop the tranny for the 5th time. :dang:

I still don't think its the syncros

il find out tommaro. il post up what the problem was :tu:

i think its your hydros:w2:

put new hydros in already from southbend. the same hydros they use to push the 850 h.p dual disc? changing from stock to the southbend hydros didnt change a thing. maybe i got a bad set of hydros?:humm:

Bent clutch fingers due to the heat maybe? Bent clutch fork? Since you replaced the hydros, sounds like you are down to mechanical mishaps....

did your adjustment jam nut for the hydro move? Try re-adjusting it maby

tryed that already to no avail :dang: ive been on google for 4 hours and i cant find anything. a good friend of mine owns a transmission shop. im gonna go talk to him tommaro. then im gonna try some differnt oil and stuff like that. try all the little things before the tranny gets dropped.

the wrong oil will make it harder to shift, I have been running royal purple for a year now I have noticed harder to get into gear sometimes. try different forums I will ask around. Good luck man

thanks for all the help. looks like im gonna have to drop the tranny.
