Breaking in new parts
So, I have a fresh trans and rear differential going in. How in heck do you guys break stuff in? It's gonna take me forever to put 500mi on this thing!
Do you guys actually daily the cars until you put all the mileage on? |

My evo is my daily...........

When I had my trans and t case rebuilt by tre John recommended street driving it. He told me to go easy on it and have varying speed and rpms thought out all gears. Cruising on the highway in 5th gear was not preferred. My .02 cents

TRE gives break in instructions. 5 heat cycles of about ~15 miles of mixed driving. Keep it under 55-60mph for the first 100 miles. After that, drive it easy out to 500 miles. As stated, freeway cruising is not ideal, you want varying loads and speeds. And for the trans, you want the synchros and all the gears to break in, so street driving is ideal.
Changes fluids after the first 1000 miles, and then again at the 5000 mile mark. |

Pick a nice sunny day and drive to Sacto and back on 5.....that'll put almost 400 on it. Of course daily it would be the way to go. Works the gear box with the new synchos and does loading and unloading of the bearings and surfaces.

I read all that. It's gonna be tough because I hardly drive the car. The first change @ 500 miles will take god knows how long. After that , I'm good because it takes 2-3 yrs to put on 5k miles (kidding. I change annually). |

Yup that is why I recommended the second option....but if you want it done quickly I gave you choices...Lol....Just not what I would do. Others appear to concur on my 2nd choice as well.

Did you change final drive or other trans gear ratios / TRE Maxxlock diff?
|
So you complained about spending $1500 on getting a proper diff built, and now you seem to be seeing how to work around the break in instructions from the person who built the diff.
I'm sure this will end well. |
In B4 "why is my brand new TRE diff whining, there's only 1200 miles on it."

Race car drivetrain parts get broken and or refreshed often. If you want it to last, follow his instructions.
