Transmission break in?

[92saturnsl2]

I just had the transmission replaced in my '15 Sedona with a remanufactured unit from Kia. Is there any break in procedure at all for transmissions, or any steps I should take / things to avoid during the first few hundred miles or so?

Not quite sure to what extent new parts are used in these particular remans, or what gets reused. I assume being a reman and not rebuilt, there would be a good portion of new parts inside an old case, but feel free to educate me if my assumption is incorrect. The transmission itself from external appearance looks brand new, clean enough to eat off of.

Is there any logic to an early fluid change to remove any wear metals from new parts breaking in?

Typically a transmission doesn't need a break-in, other than some shift cycles to let the adaptive algorithms self calibrate the shift times.

OEM reman's are some of the best units you can get. It's basically a new transmission in a cleaned up case. The OE is very strict with it's QC. I've pretty much moved to using all OE reman'sat my shop due to the warranty and almost equal price compared to my local rebuilder.

For example: I can get a 6L80e from my local Chev dealer with a 3 year/100k warranty for something like $2,800. My local rebuilder would want almost that for the same unit with a 12/12 warranty, extra charge for a warranty beyond that usually ranging from $250 to $500 additional.

Rebuilt-remanufactured are the very same thing, the only difference is who performed the deed. If the manufacturer it's remanufactured if an indy it's a rebuilt. Some times a rebuilt can be better since you pay & are billed for each new piece they could replace evry moving part, whereas in a remanufactured they have a set of thing to replace and others only if deficient.

I would think the friction plate assembly would benefit from not trying to manually rushing shifts. There are always parts that can use burnishing. JMO. Ed

I'm not sure what manually rushing shifts is? The important part is to have the adaptives get the pressure profile close so you don't have a long slip time. On the Allison in the GM pickups, the controls engrs designed a routine to sequence the solenoids to do this on the assembly line as part of the roll test.
