Good Morning/Afternoon/Evening guys and gals,
I want to know is there a proper way to break in a new tranny or the best method possible? I am receiving a new tranny through my dealer via warranty. and i am unsure how to break it in. all i know is that i shouldnt drive at just ONE speed on the highway or around town. I should vary the speed. i.e. highway alternate between 55-70. around town should i travel between 30-50 variating my speed depending upon speed limit... also when i'm in residential area's should i still do the philly slide's through the stop signs or come to a complete stop?

I believe he is asking how to do it, not making a how to....lol

 

I moved it from how-to

 

oh ok....i was confused....sorry

To the op...I have never heard of a tranny breaking period, only heard of a clutch break in period...

 

ok so there is zero break in for a brand new tranny

 

I didn't do anything special with mine

 

me either

 

New tranny shouldn't need a "break in".

Don't bag on it too hard for the first few days (no powershifts ) and, if you are really ****, change the oil out after a week or so just to make sure there is no leftover loose **** floating around.

 

i'll just baby her for a few days and i am DONE with powershifting f that... maybe if i got the WOT box... lol but all the dealer has to do is put the cradle back in/ axles etc... and alignment i think that will be done by 5 p.m. EST

cause i know damn well if i was a tech i wouldnt wanna come on in a monday like damn i gotta do this still! lol

 

yeah, I am changing my fluid out soon though

I've had the new tranny for about 6 weeks and I'm switching to Redline oil

 

so some guy in a turbo integra type R said i need to break in my new (used with like 40k miles) transmission. da fuq?

any insight on this? i obviously think hes wrong but hey you never know.

and old thread bump because i used search

 

a manual transmission doesnt need any specific break in, however to make sure the syncros seat in id do some in town normal driving. this will help the syncro break in so it matches the cone of the gear perfectly. if you start power shifting right off the bat the syncros could slip on the gear causing gear clash. you dont have to do anything like varrying the rpm on the freeway, you dont have to be gentle on the throttle, just dont shift real fast.

 

yea thats exactly what i thought. Im done with powershifting my car anyways.
