2017 Toyota sienna 220k miles, Transmission toast

Topic starter

I keep hearing 220k miles is great to get out of this transmission but I'm really disappointed that 220k is all its got! We own quite a few toyotas (2003 camry 215k miles, 2003 camry, 275k miles, 2005 camry, 410k miles (standard), 2009 sienna 295k miles), 2017, 220k miles and transmission is toast 🙁 ) 

2017 was the first year for the 8 speed transmission (I knew better than to get a first year of something!) Engine is doing great and now its in the shop to get a rebuilt transmission (going to cost about $9k) But I guess a transmission with no changeable filter is due to get less miles over its lifetime. 

Now my question is, is it possible to put on a filter of some sort that we can change regularly to possibly get more miles out of the rebuild? (We'd have a professional do it if it were a major piece of work). The van is in perfect shape, 1 minor accident that dented the fender (and was fixed) so no dents or dings on the body, living near Houston, its rust free, and oil changed every 5k like clock work. On its 3rd set of CV Axles (Also what is the best brand for CV Axles?) Last set we got 150k out of but they are starting to click again so want to get those taken care of while doing the transmission work.

You shouldn't have rebuilt that transmission. You should've purchased a factory remanufactured transmission with a good warranty and have the mechanics put that in. I have a 1999 Ranger, it only has a 4-speed automatic. After I got it back, apparently valve body was messed up and the transmission would seriously jolt from 1st to 2nd gear until the transmission warmed up. The rebuilder tried three different valve bodies before they got it somewhat right. Most transmission shops only have a 1-year, 10k mile warranty as well.

Was it serviced every 50k or so?

that's insane. A tested and ready to run remanufactured trans with all new parts and warranty shouldn't be more than $5k installed.

No.  And I doubt that's what killed your old transmission. Better just to change the fluid more often.

OEM most likely. Some say Toyota CV axles should be overhauled not replaced, as there is no good replacement.

that's not bad.

It sounds like your mechanic is spewing horse manure. Most automatic transmissions have a serviceable filter. A google search finds plenty for your transmission

I personally have not heard of doing something like this, or at least in a way that makes financial sense. Maybe someone else can chime in. However, the best way to get the most life out of the transmission is draining and refilling the fluid, along with filter, every 30-50k miles. 


@fishingandcarsenthusiast123 Oh I should have added that in the original post! We did drain and refill once a year (which was about every 40k miles) (Lots of highway miles and living near Houston)
