Ok guys, not to interrupt lol, but here is an update. As he and I (the shop owner) suspected, it is more than likely 6th gear again. They are tearing it apart this morning and will be calling me as when they find out. He said it seems to be just a few broken teeth from the sound of it rather than all of them this time around, but it is probably still shot. He said they have learned a lot about these transmissions lately and the main failure seems to be inadequate lubrication. He said they have been packing the bearings excessively since that came to their attention, but I mentioned the overfill thing, he said he never heard of it, but liked the logic of it as long as it doesn't get filled to the point of creating foam in the tranny. They are going to overfill it for me when it goes back in. He said as far as the 6 to 5 speed, I would have even more problems with a 5 although it may be a little cheaper but it would give me more problems. Another problem I have been trying to get them to look at for a while now is the clutch, and the owner finally drove it and agreed, something is not working right. If I put it to the floor, it still doesn't shift easy and he agreed, it's not disengaging properly. He said they have seen the pedal/mount under the dash flex in these trucks, and to correct it I am going to put an adjustable master/slave in, we will see. On an interesting side note, he is a Royal Purple dealer and he WILL NOT use their Synchromax or anything like it because from what they can tell on re-builds, it doesn't seem to lubricate like it should, so they only use the Mopar stuff in them. A friend of mine who pulls also said only get the Mopar stuff. So for this round, the 6 speed stays and they said they will stand behind it again.

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!

how many bearings? how much fluid? you never know but it does sound alittle high, i would be quite ticked off if they said they would take care of it, didn't tell me what was wrong and then just fixed it and handed me a bill like that. from the sounds of it there was no discussion of paying for anything from the beginning

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

Take it back ASAP. They need to pull the gear set and IIRC cut a slot in the case above the bearing on the mainshaft. They should have done this in the first place. That may not be the right place, but I'm pretty sure it is. I could call my trans builder and ask him. Anyhow he has built a chit ton of NV5600's and he says they don't leave his shop without this mod done to the case. I told him about overfilling by a quart, and he had no qualms with it.


A 5600 can take whatever a 4500 can........for the most part. And most definitely down in the lower power levels. No way a little lugging on flat ground with no load killed his trans.

i pull 16,000lbs on the highway in 6th gear with my smarty on sw-4 and i haven't had any problems yet, every transmission is different, could be the way it was rebuilt, the way it's driven,etc

I'd like to know more about this slot, I really don't think they know chit about the 6 speeds, they seems to be learning at my expense from what I can tell. It wasn't really lugging that much, 1500-1800 RPM's and it was about a 5 mile trip, other than the bad roads it would have been in 5th most of the trip. They don't seem to think there is any benefit to the over filling thing, he said there is plenty of lube on 6th and the bearing since it didn't look burned to him. As to the exact amount of what all parts were involved, he said it would be around $650, but oddly enough he couldn't get his printer to work yet had no exact total, hmm, shoulda been right on the screen in front of him if it was just a printer error!

you have 2 choices after a repair warranty expires. word of mouth is worthless in court,
unless you have something in writing?

1. pay the bill or
2. give them the truck
most states have a vehicle repair shop lien law. the shop can send a repo tow truck and haul your rig off.

if they put in the tranny lube in the Dodge/Chrysler jugs, it's $25 a qt. $100 right there.

yes, they made some money on the parts but is it worth losing a day's pay in small claims court and still maybe getting $100 back?

most shops only give 30 or 90 parts/labor repair warranty

few hotshotters tow heavy in 6th in an NV5600

Towing 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.

Steelhead01, I understand all of that but given that what is in writing is what they go by, what do they have in writing? I never agreed to any services, I agreed to let them look at it because they would take care of it. They have a service form they have customers typically fill out which they sign agreeing on how much they will pay and if it exceeds that amount it must be approved by the customer. They never had me do anything like that this time. You say to get $100 back, but I have not paid them anything yet because they "couldn't print the receipt" but they couldn't get me a total either oddly enough.
Now what I could do is get the complete list of all the parts used, since I only have to pay parts, go find those parts and take them back to them and say here are your parts and that would be that, take a witness and there is nothing they can do. Or, since they want to be a crooked bunch I can just pay them oh say $10 every time they send me a bill, as long as I show effort in paying the bill there is nothing that can be done unless it specifically states on the original invoice that past due unpaid bills are subject to a late fee. Still I would just be paying a late fee on top of it.

What it comes down to is the fact that the one and only reason I allowed them to work on it was because the owner had said they would fix it for me under the warranty, it was not a problem because I even specified that it was 2 days past the 12 month warranty and over on mileage for the 12K warranty. If he was an honest businessman and told me I would be paying for it, I would have just ordered it all myself and done it, 6th gear is a no brainer to access and change, not that difficult and I wasn't in a pinch where it had to be done right away, they just offered to "take care of it."

Here are the pics of the 6th main and counter. On a side note, I find it interesting that the teeth were broke all on one side, all the way around the counter and only one side of the main as well. Here is the link, the shiny oily set is the latest.

i 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)

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 350hp
