Question for NV5600 experts

[JLovas]

About a month ago I ordered a rebuilt NV5600 with power lube package from Standard Transmission. The synchros were wearing out on my transmission and I wanted to update to what I perceived as a better transmission in regards to better lubrication. I had confidence they were a good business to deal with based on information I've read on the TDR perceived and the quarterly publication. At the time of the transmission swap, which I did myself, I also replaced my clutch with South Bend's new street double disk which included new flywheel, throw out bearing, pilot bearing, ect.



After I completed the install, I had difficulties shifting into 5th gear, and 6th gear shifts were not possible. It took considerable effort to shift into 5th gear and when trying to shift into 6th, it feels like it only shifts half way into gear, and when I release the clutch pedal the transmission grinds as it kicks the shift lever back to neutral. I can't even hold the lever in 6th gear position to make it hold that gear. Gears 1-4 and reverse work as they should and the transfer case shifts into and out of 4wd just as it should.



After conservations with South Bend Clutch and Standard Transmission, it was recommended I install South Bend's HD hydraulics. After I installed that, 5th gear shifts felt normal again, but I was still having the same problems with 6th gear.



After further conservations with Standard, the sales person I was dealing with said they would get another transmission together and ship it to me as we feel I may have gotten a defective transmission from them. I've had numerous phone calls with them and feel like I'm getting jerked around a bit. My sales person told me on July 20 that my transmission was almost ready and he would be in contact with me the next day before they shipped it, and I have not heard from them yet. I'm concerned that their good reputation they seem to have is not what I'm experiencing.



I'm leaning towards saying the hell with things and put my old transmission back in. While pulling the shift tower off tonight, I noticed a difference in the position of the puck that the shifting lever fits into. Does anyone know if the orientation of this puck could be the source of my poor shifting characteristics?



The top pic is the rebuilt transmission currently installed in my pickup and the bottom pic is my origional transmission. Both pictures are looking at the transmission the same way, top of pic is towards the bell housing.

So, . . . Did you resolve the problem?

 

[Mhannink]

looks like the shift rail is flipped around it could possibly be the problem but i really dont know.

 

[JLovas]

Corey at Standard transmission said the orientation of the saddle doesn't make any difference. I'm in the process of installing my old transmission again while I wait for the new one, which has been on order since July 6th.

I believe they're jerking you around. You may want to speak with a good attorney.



Even if they make good on another transmission (that works), they should reimburse you for the added work you made in switching transmissions.

Any warranty I have ever seen only replaces the defective part. That's why you don't bring parts to your mechanic. If you bring him a part that goes bad, YOU pay for the labor. If he supplies the part, HE eats the labor.

Actually the mechanic will often get reimbursed by the supplier of the defective part for his time. Suppliers know that if they don't do this for a good customer, he will go elsewhere for parts next time.

I have never heard of a consumer warranty paying for labor done by the consumer in the event of a defective part.

There are usually two sides to every story. The fact that the OP reported an initial problem with 5th and 6th gears that was partially corrected by replacement of his clutch hydraulics makes me wonder if there are additional details here.

I would expect Standard would want the reportedly defective transmission returned to them immediately so that they could inspect and repair it if necessary then return it to the customer.

I have heard that NV-5600 cores and cases are in short supply.

Any time there is more than two people running a business things can fall through the cracks.



I've only heard good things about standard. Call them. Find one person that seems to genuinely care, get their direct number or extension. Call them every time you think about it. About seven times a day is good. Don't be mean or rude ask when you will receive your replacement you were promised and tracking number.



This also works on credit card companies for silly fees. Your just another angry caller until the twelth time they have talked to you in one day I've never met Brenda but I'm sure she hates me more than any human on the planet.

Well, I received the 2nd transmission from Standard a couple weeks ago, promptly installed it and have about 800 miles on it so far. Initial driving thoughts were positive as all the gears shifted as they should. After about 100 miles of driving, I noticed a ticking or light knocking sound that corresponded with the speed of the input shaft. The noise was evident in 1st-5th gear, and I couldn't hear it in 6th, but it is probably due to increased road noise at higher speeds. I called Standard about this issue, and they offered to double my warranty to 24month/24,000 miles and they didn't seem to think the noise would have any adverse effects on my transmission. Now with approx 800 miles on the transmission this noise has nearly diminished and is only evident at low speeds. I respect Standard's opinion when they told me not to let the noise bother me as I cannot "feel" this knock in the steering wheel, drivetrain, or shift lever. The transmission shifts as it should, runs normal temperatures, and I cannot detect any additional drag in the drive train.



Just because I'm a nut for having spare parts on hand, I had my OEM transmission rebuilt locally and will put it up in the shop to have for a spare. My OEM transmission needed a bearing kit, synchros, input shaft, and a large beveled gear that had some surface treatment missing from a couple of the teeth.



As per Standard's recommendation, I put in 7 quarts of amsoil transmission oil in my new transmission. I wish my owners manual would have told me to run that much oil, otherwise my OEM transmission would have lasted longer.

I have heard that NV-5600 cores and cases are in short supply.

Standard told me they had 8 cores, but 0 rebuilds on hand when I called and reported my problems with my first transmission. They didn't seem to be in too much of a rush to get mine, they told me to drive it as is until they got another one rebuilt and shipped to me. After I got my 2nd transmission from Standard I shipped the first transmission to them as per there request. The world has one less core as I kept my OEM transmission and had it rebuilt locally and have it sitting in my shop for a spare :-laf

My 5600 has been perfect since Std. rebuilt it 24,000 miles ago. In my experience, "transmission" problems often turn out to be clutch problems, which in turn often turn out to be high mileage issues (pilot, throwout bearings, wear, crud buildup, etc), or improper installation where the bolts aren't tightened in steps in a star pattern, or the trans input is allowed to bend the hub of the clutch disk.

I'm glad to hear that your transmission has been holding up well Joseph. Your article in the TDR was one of the main reason why I chose Standard. While installing my first rebuild from Standard, I also installed South Bend's new street dual disk, which included their flywheel, pilot and throw out bearing. After I pulled the first rebuilt transmission in exchange for the 2nd rebuild from Standard, I double checked everything related to the clutch and re-read the installation instructions to make sure I did everything correct and I found everything to look good.



As I said previously, the more I drive this 2nd rebuild, the more I like it. I'm also well pleased with the street dual disk clutch from South bend, really has a nice engagement and holds my smarty at the highest setting I've tried (130 hp).



Probably wasn't necessary for me to rebuild my OEM transmission as a spare, but I do have dreams of installing a 12 valve in an '82 Dodge 1/2 ton (was my grandfather's pickup) that I have sitting in my shed, so maybe the 5600 will come in handy some day.
