I hear this happening more and more over the past few years. Rear diffs fail after a while, sometimes.

Front differential. LGT 3.272 OBXT 3.5xx or something like that. Key point is it's different. You would at minimum need to at minimum keep the original front diff ring and pinion with the car, or you're going to tear up your center diff quick. IF those are the only differences, then you'll be alright. VBs are the same, most internal parts are definitely the same, center diffs are the same, but some people I've worked with have ended up in hell trying to get mispatched parts to work, so do so at your own risk, after pouring over a split screen pullup of every part number for each trans that you can find. Just my $0.02 Or just get the rear diff ring and pinion or total assembly to match. As long as they match you are likely good. I don't know whether you would throw codes or the various speed sensors feeding the various CAN modules (ABS & Trans) would leave you alone after they talk to each other.

There's nothing wrong with resetting the TCU, it's just that 95% of the time it accomplishes no added benefit after it is done making learning adjustments. I do not know what is wrong here. VB could indeed be defective. All VB bolts should be torqued to 80in-lbs (NOT ft-lbs), and trans fluid level should be verified while hot, engine running, after car has completed a full hot/cold drive cycle and cooldown, as I have seen a perfect level drop as much as a full quart.

Amazing work being done here, very impressive. Hope you guys get pretty far into disassembly.

Updated first post to bring this forward 5 years in relevance.

Completely on board, just messaged utc_pyro about details of getting it shipped. Should take under two weeks.

snow05gtRI is most likely on the right track. The problem is most likely with either your tune or your engine. The transmission isn't going to stall your engine. I could write a 10,000 words about why, but I think you get the point. The ECU is being fed some data that is outside of desired operating range at idle. Load, MAF, MAP, something is off.

Yes sir, still upgrading valve bodies regularly.

How many miles? Sounds like you already know what to do to fix it. 2008s usually are pretty reliable, not sure what's going on with yours.

Following up on your direct message so it's out there for public record: If you put it back together with the same clutch pack, or use new OEM frictions in the same config as what you had, then you do not need to re-shim. Re-shimming the center diff clutch is a giant pain unless you've done that kind of thing many times.

I never bought them, as I realized you would have to do some serious modifications to the two knuckle caliper mounts. Wouldn't just be a simple bracket, the knuckle mounting is too intrusive. I've got F40 style brembos on that will be fine. You would need a mill and even then...

I've seen this a lot in various forms. It's likely related to the engine. So many support issues I've seen with the 5EAT have been resolved with something as simple as an engine vacuum leak. I do not know what the exact mechanism is, but it's the ECU sending incorrect signals to the TCU. ECU itself is fine, problem is an input somewhere is not what the TCU wants to see at certain moments, such as during your bad shift. The solenoids are easy to change, just one torx bolt and gently pulling it out (plastic held secure by two o-rings). They are now also easy to find, and not terribly expensive. Just make sure you don't buy one of questionable origin, as with any aftermarket replacement part. What was your CEL Code? Not P0700, but the next code, something like P0741. Let's first double check that you replaced the correct solenoid... PM me too about this, happy to help. For a time I really came to dread dealing with my LGT and all things related, but I'm in a better place now and I am starting to enjoy it again. Might be on here a bit more often

It likely won't do anything, exceptions are rare. http://legacygt.com/forums/showthread.php/5eat-free-ssm-thread-151177.html Change the fluid until it's fresh. Lucas Trans Fix might help depending on the mode of failure.

From what I have read, not even the Cadillac 4-pots fit under these, do they?

Now the question is whether the "I want a six piston caliper brembo to fit under 18" wheels" people are serious or are just expressing their generalized interest...

Different shaped pads aren't really an option If anyone wants "perfect" alignment then there is the 4-pot option. The only people who would get upset about such a thing with a 6-pot are the same people who don't actually do ambitious upgrades in the first place. In other words, a non issue. /rant It was a trick question. It doesn't cause a problem. I had this happen on an early set of rear brembo adapter brackets before the good KNS ones came out. You literally just have an unused brake pad lip form and maintain itself on the part of the pad that does not engage with the rotor. It's not a problem, it's just not "perfect". You could cut it off with a box cutter if you wanted, otherwise it will take care of itself. Putting a 6-pot Brembo Caliper on a 326mm rotor was never going to be perfect, but this is surprisingly good, which was more the point of my post

For you guys wanting to run the Gen 2 CTS-V 6-pot calipers, do you care whether there is 3mm of pad overhang on the outer corners and inner middle of the pad? http://legacygt.com/forums/attachment.php?attachmentid=240848&stc=1&d=1479432101 http://legacygt.com/forums/attachment.php?attachmentid=240849&stc=1&d=1479432101 Yes, neither do I

The mounting ears of the caliper castings for the Camaros appear to be longer than the ATS. If that is correct, then the calipers and pads would stick out too far from the rotor

Did you fill the torque converter with ATF prior to install? Assuming you did: This is binary. Replace valve body. Pass/fail. If fail, it's internal to the transmission. You have a good grip on the FSM troubleshooting, which is key. Hopefully pulling it apart reveals a smoking gun. If you find one clutch pack burned up, definitely replace any related seals.

I do indeed have plenty of these control boards, and inhibitor switches, depending on which temp sensor got damaged. Would be a relatively easy swap, and will eliminate any potential issues in the future with regards to one sensor reading X and one reading a distant Y. Just in case you want to go at it yet again.

I know we texted about it but in case anyone reads this in the future, your input and direct tolerances are good!

I'm just going to PM you my number so you can ask questions without my sometimes long response delays, if you prefer. Keep it up!

PM replied. Sorry for the delay. I would love to say I have a valve body for the 5th gen, but I'm afraid not. I've since learned to stop over promising about what is possible in the future. All I can do is what I can do, and it's a lot more complicated to figure certain things out than I ever thought.

I love your build! We'll talk center differential bushings.

Yup, bit more to it than that. The gear teeth are physically the weakest link in the power train, but there are several things that actually happen when a lot of torque is loaded and failure occurs. Kind of like if you have bad knee pain there are many things you can do to improve it, from increasing mobility to strengthening the joint, to taking advil, to realizing your ankles and hips might be the problem thereby causing the tension up or down the kinetic chain. And then the number of fixes compounds to be so many, and you don't know whether the chiropractor or doctor or personal trainer or yoga teacher is the right one since each one has solved it in a different way. That's why I keep saying cryo, even though you just installed the bushings. Rarely is someone holding a diff input shaft in new condition without a huge time crunch to get the car back together. As a 5EAT healthcare consultant, I care about fixing this issue probably more than the average 5EAT driver who just broke the diff and just wants their car back. Totally get it. I should have a copy on my computer, send me your emails.
