I was just wondering if a trans that was rebuilt(not including gears) needs to be broken in before really revving it up? Any response is appreciated. Thanks

I'd treat it like a new trany....no hard launches or speed shifting untill at LEAST 500 miles of easy driving.

i asked this question when i installed a rebuilt tranny. unless it is specified in a warranty, there is no need to wait 500 miles.

Hmm....what about gear break in? Gears wear into eachother over the first few hundred miles and create the "groove" that they're going to run in for the life of the gear....abuse it in this period and you run the risk of chipping gears and then having those chips loose in the trans. It's the same concept of not beating an engine until it's broken in.

dont get me wrong i did not go out and beat on it after finishing up the install. i drove about 250 miles and wanted to go to the track and that was basicly the answer i got when i asked the question.

Yeah i don't think it's going to explode if you don't break it in but i mean 500 miles isn't an eternity ya know? It's one of those things i've heard my whole automotive enthusiast life so i stick by it. At the very least it couldn't hurt right?

I would worry less about the gears and worry about the new roller bearings.

dont worry about breaking it in. drive it like you normally do. if something is going to break then it will do it fairly quickly and it will most likely be something else that caused it besides any "abuse"

any beating on the tranny now will have no different effect on it as it will when its "broke in"
