I'm telling you, you'll have fewer problems w/ a well built 4500... but, I think cruising so long at low speed in 6th is what killed your truck. my red 98 12v was set up to tow in 5th with 35" tires... it basicly acted as a 5sp truck w/ 3.54's, but I had an extra gear while empty
Ok guys, need some advice here. The shop who built the tranny in the first place (12 month/12,000 mile warranty) told me to bring it in and they would take care of it for me, not a problem. The 12 month warranty ended January 9th, it busted on the 11th. I pick it up today and I was informed (after paying almost $2700 to have it re-built the first time) that since I am a good customer I would only have to pay the $650 for the 6th main and counter, a couple bearings and the seals to put it all back together, plus the fluid. Anyone else think this is shady at best? The $650 was just parts, they picked up the labor since I was a "valued customer" even though they never called to tell me what was wrong or give me an estimate, they just fixed it cause they would "take care of it" and threw me a bill that seems ridiculously over priced for a main and counter gear set! Just a note, on the first rebuild invoice, the 6th gear main was $142.40, counter was $172.83, seems impossible for a couple bearings, seals, and manual tranny fluid to cost almost $350!
Thats true, the aint cheap but have a great name, sometimes its worth the money to pay and get a good product, i like Bluementhal, i am actually from OK and they are nice to deal withTowing heavy in 6th is fine as long its on flat land, but when hitting hills and grades its best to drop down to 5th.
I would check with Bluementhal in Oklahoma. They have a good reputation with rebuilding NV5600s.
I agree with you! I think they are the strongest tranny they have put in our trucks, i have had one of each and put the nv56 through alot more than my 4500 and g56 and have had no issues with it and was well over 1000 ftlbs, and has seen alot of 4wd launches and 40ft loaded trailors. My g56 is broke and i have broken my nv45 with a 2wd truck with only 350hpi dunno what has been said thus far, but if you got your tranny rebuilt and it broke i would bet money they used korea parts. genuine nv shafts and gears are a MUST when workin with the 45 or the 56's. . .you shouldnt be breakin your 5600 unless A) your bearings are bad and the shafts buckle, B) you do something incredibly stupid, C) you put copious amounts of power to it (well over 1000 lb ft), or D) THERE ARE KOREA PARTS INSIDE.
especially if you are dealing with a tranny man you dont know, he probably used korea parts. a lot of tranny builders get nv45's and 56's for routine bearing rebuilds and they rape the guts. i.e. they take your nv shafts and gears for other projects and replaced htem with cheap, accessible korea parts. your authentic nv parts are like gold in this world of endangered nv56's.
ive seen korea parts break a few days after install on multiple occasions. a genuine nv56 is arguably the stoutest transmission ever put into a light duty truck, i had 200,000 miles on my last one with extensive abuse and double its power rating the entirety of its life. i broke my main shaft due to bearing failure. i have some authentic parts out of that tranny if you are interested, and no im not sayin all the above because im tryin to sell you parts, i couldnt care less if you buy them or not (tryin to help ya out with info not play salesman)
