I'm not saying thats what you should do. You should try and find some stuff on them and see which one fits your needs more. Thats what I did and I decided to go with the Auburn but the Detroit might fit your needs just fine and for what you do you probably wouldn't break it. Either one should be a great choice it just comes down to which one fits your needs more. I really wish I still had the links to threads I read about them and I'd give them to you for you to read. There were quite a few of them though and I didn't save the links sorry.

 

Nice. Let us know how it is. Hopefully it will be great.

 

So did you get the LSD or not?

 

Sorry I didn't realise I was offending the lord of all things differential!
Just cause yours broke doesn't mean they all suck. If you work on cars long enough you'll realise the people the bitch and complain the loudest are usually the ones who abused /neglected their vehicle and were pissed when they had to pay to fix it. Gotta pay to play that's how it goes. How often to you see someone boasting "Man I dove the s*it outta my stock truck and she never left me down!"

But everyone get an opinion right?

So I'll back mine up:

1 My truck still has the orig rear diff and at over 10 years old the LSD is still tight even with 33" tires and off roading. But you guessed it I don't drive the s*it out of my truck.

2 The diff in question here isn't even confirmed worn out / broken and we all know how the owner drives.

3 I have personally rebuilt dozens of 9:25 axles and inspected even moreand the vast majority of the LSD units were fine.

4 The ones I've seen that were worn out / broken were almost always neglected or abused.

5 While certainly not a HD design the Trac-lock is far superior to a lot of other factory LSD units. The gm Gov-locks are weak and the stock Ford 8.8 LSD is junk. I myself tossed my new Ford8.8 LSD and installed an Auburn unit. These are only 1/2 ton trucks remember! Nothing is bullit proof!

I stand by my opinion!

I don't expect everyone to agree as I'm sure others have had different experiences.

 

Got my truck back today. Took her out to get it all cleaned up, and she is really shining...my happiness only lasted so long. The truck is wining in first gear and takes awhile for it to shift, and then when it does shift, it clunks in HARD. Second gear, it will keep wining and wining until you let off. Third get shutters in and then clicks into 4th. And 4th is a nightmare and shutters the whole truck, truck will not go over 40 mph. I am keeping my cool though. I had one of their guys take a test drive for me. Says he needs to reacalibrate the pcm and add a resistor...

I'm dissapointed they didn't have this all sqaured away before I jumped into it. For $4,000, they should have had any weirdness taken care of and that truck running in tip top shape. I know they did not test drive it because they wouldn't have let me take my truck back shifting like that. The guy is trying to blame the fact that the engine misfire code that come up on them is causing this...I beg to to differ. The truck NEVER did this. That other tranny was weak, but it actually shifted very smoothly, but would bob around in the higher gears. I'm to say the least a little shocked right now, I don't know how the truck isn't running anything but immaculate after $4,000 was given to them to make my transmission bulletproof designed for the truck. I'm dropping it back with them tomorrow morning, he said it just needs to be reacalibrated for the 35" tires. I will let them do their magic, but they will not get rid of me until that truck is riding in the best condition of its life. I'll see how it goes tomorrow. For now I have the truck in my possession, and she is looking mighty clean lol. Just too bad it has to go back into a dirty shop again. These guys are the best in town, yet they took the lazy route on their top customer, and didn't finish the job off. For $4,000, there is no excuses in the book for the truck not to be shifting PERFECTLY...none. I'll have more updates for you guys tomorrow when I get it back, until then, I'm just going to have myself a cigar and cola, and try and not think about this.

LSD is defiantly waiting until the transmission is PERFECT, period.

 

WOW !! , if it wasnt for bad luck , you wouldnt have no luck at all...with them saying about the pcm and adding a resistor , i think they will be trying to cover something up ... i like to see what parts they put in it ( build sheet) can you tell us this ? normal trans rebuild is 2500 with HD parts ,shift kit , labor..

 

I don't like the sound of this resistor business either. Can you stop payment on the cheq?

 

[sm=icon_rofl.gif]neon you gotta be kidding me.

 

This is why I went with an APS so I don't have to worry about this stuff. Them claiming they need to add a resistor and change the PCM sounds like a cover up to me also. When I had my transmisson put in they didn't have to touch the PCM. The only thing they had to do is adjust the TV cable. That would make it shift early at WOT but it doesn't make it whine, shutter, or any of those other issues you are having. Sounds to me like you need another rebuild but I guess I could be wrong. This sounds like my buddy who had a transmission put in his 89 Dodge. It wasn't right from the get go and the shop kept saying it just needed adjusting. Finally after adjusting it and never getting it exactly right 11 months later it died on him. Well the company the shop bought the transmission from had gone out of bussiness. The shop ended up getting it taken care of but he was without his truck for 3 months which is bad considering he used it for work everyday. He had a spare truck but it wasn't in as nice of shape and wasn't meant to be driven but a few times a year. Turns out after all they tested it and it hadn't needed adjusting the case was cracked and causing all the other problems. Then the guy that runs the shop said he had another guy in there with the same transmission bad now and he was having to pay out of pocket to fix them. This guy is a pretty well known guy around here and told me how great these transmissions were too. No thanks I think I'll spend the extra and get the APS that people aren't having problems with.

What happens in 3 years when the warranty runs out? Sure they might keep messing with it and or replacing it until then but what happens when the 3 years are up and it goes out again? I dont' know I don't want to take those chances. I'd rather just pay the extra for a good transmission like the APS.

Wanye told me when I got mine if you hear a wining, grinding, or clunking usually it's a serious problem. If you don't hear any of those usually it's someting that just needs adjusting but those you noises aren't usually something that can be adjusted usually it's a major problem.

See why I'm telling you to go with something thats known to be good now? I'm not trying to be a dick just trying to save you from spending a ton of money on crap.

 

I just know when I posted over on Pavementsucks.com almost all of the guys said they had had the exact same clips break off and that it was a common problem. Even some guys that I don't often see complaining chipped in on that thread saying they had the exact same clips break off. I'd be willing to bet those clips are what broke off Neons truck. Rebuilding it might be cheaper but why not just pay a little extra for a quality unit that I haven't heard anyone have a problem with. Even the guys that do beat on their trucks are saying they are holding up.
