Break In Period, transmission fluid change required?
In a few days (hopefully) I'll be receiving my '21 1SS 6MT. I know there is a recommended 1,500 mile break in period, which I'll abide by, but when talking with the sales guy at the dealer I'm buying the car from, he said at 1,500 miles a trans and engine fluid change is recommended. I've bought one new car before (2018 MX-5) and I did do an oil change at about 1,500-2,000 miles, but never even thought/read anywhere to do a trans fluid change.
Is the trans fluid change necessary? I can understand the reasoning, just in case there is anything in the fluid from factory. However, oil changes I've done hundreds of times before, and was going to do that myself at 1,500 miles, but I've never changed trans fluid before. I'm a little wary to do that myself. At the same time, I don't really trust anyone with my cars besides myself, so I'm ALSO wary to bring it to a dealership to change the trans fluid. What is recommended on this forum? Trans change at 1,500 miles and bring it to the dealer? Just leave it alone and do a trans fluid change later in it's life? I will say, I plan to keep this car a very long time, so I want to do whatever prolongs the life of this vehicle (given I can't suddenly afford a ZL1, then I'd trade up). I'm also going to be purchasing a catch can to install. Thanks for the responses, glad to soon be part of the club! (I do have a '69 vert, so I'm kind of already part of the camaro club, just not the 6th gen club). |

Diff fluid change is a must. It's specified in the manual.
Trans fluid is at your discretion. If you plan on tracking or AutoX'ing the car, I would change the Trans fluid. Both Diff and Trans aren't much more complicated than oil changes. You'll just need a fluid pump. https://www.amazon.com/dp/B0853CNLYZ/ref=cm_sw_em_r_mt_dp_PSNTN7EGX9DTVCFFQRQB?_encodin g=UTF8&psc=1 One tip I can offer...make sure you get the fill plugs open before the drain plugs.

I do have a lift, so changing fluids isn't really a big deal to me as far as ease/cleanup. I've just never done a diff or trans before and I guess in my head I'm thinking it's some complex thing. I've been browsing this forum all morning and did come across a write up for the trans fluid change on the DIY section. It actually did seem extremely easy. Looks like I just need to get one of those pumps, and figure out the correct fluid for trans and diff. Thanks for the response! |

I still haven't gotten around to changing my diff fluid yet. 16 SS with 26k miles. Planning to do it soon. What fluid are you guys running when you change it?

Even for track manual doesn’t say to change trans. My autocross buddy who is a gm tech didn’t even say to do it. Just do oil and differential. But up to you.can’t hurt.

Rear diff.: the car must have 1500 miles (break in), then change diff fluid before the first track event, then change diff fluid again after the first track event, and then after every 24 hours of track use. It also says any damage to the rear diff. during the first track event will not be covered under warranty, so don't push it too hard during the first event. Brakes also have to be burnished before track use. The manual also recommends high temp. brake fluid. There are other specifics as well for track use recommendations/requirements in the manual. There is some misinformation in this thread. The break-in section says nothing about changing diff fluid or transmission fluid for regular day to day use after the break-in period. It lists the first diff. fluid change at 45k miles (for limited slip diff.). I can't even find anything in the break-in section about changing the oil after 500 or 1,500 miles (it does mention to check it during every fuel fill since the engines can use more oil during break-in). I'd be curious if the manual specifically mentions changing the oil after break-in, or if that is just something people do because they have always done it...I think most people do just to be safe and for piece of mind. Me included - I plan to change the engine oil after the break-in period, just because. I think it could be implied that if it's good to do before track use, then it couldn't hurt to do after break-in (i.e., the diff fluid). Overall: Read the manual carefully and it will tell you what to do. They are available online if you want to read it before your car arrives. There is a chart with recommended service and fluid change schedules in the manual.

After a lot of reading and threads here Im using the Mobil 1 0w 40. I just bought it from Rock Auto and It was not only one of the few places I found the proper Dexos 2 but it was I think $6.80ish a quart. I bought 24 Qts and a box of filters and shipping was 15 bucks. If you buy 10 qts shipping is about the same. I intend to use Tremec trans oil. I figure its their trans... and they apparently recently came out with a new formulation for our trans. I havnt decided on fluid for the diff but Im leaning towards Redline or maybe Valvoline in the proper spec.

I did my first oil change at 500 miles then again at 1K. I have 4300 miles and have actually changed it 5 times. I know its a waste but why not I do it myself anyway. Diff fluid was at 1500 miles and that surprised me how bad it actually was, did it again at 4K and it still looked new. Did my trans fluid about 3 weeks ago and switched it to Royal Purple and I do see a difference as it feels smoother during shifts. The fluid actually still looked brand new though when I drained it. I used the temp sensor to drain it so I didn't really make a mess and I have a lift so its a pretty easy job.

I did both the rear diff and MT6 at 10k miles. glad I did, found a few shavings in the trans and the diff looked terrible. Did again at 20k and they both looked real good.
