New trans needed at 35k?

[yrwei52]

EDIT: IMO... I don't believe this is a widespread problem but obviously there are some out there.
It would be nice to know a little more background on the TSB. Questionable parts supplier, predominantly city driving, towing, fluid changes help, etc? I think of any car component I am most sensitive to transmissions. I had a failure as a kid at a time when I could least afford the repair.
Here is a little pricing info for out of pocket.

$2760 with a $1K core charge + $250 shipping
No idea what the book rate for install on this is

If the problem is caused by a damaged bearing in the transaxle due to improper configuration of the transaxle case, this means the bearing eventually will wear out and get damaged unless you have a corrected transaxle case. It's just a matter of time.

Seriously, I feel automatic transmissions are more reliable nowadays. I've seen many auto trannies needed to be overhauled at 50,000 miles in the old days. Many years ago I overhauled a Borg Warner automatic transmission from my old '72 Mercury Capri which had only 45,000 miles. That is the extreme of my many DIY projects and I imagine that is also my last DIY work to overhaul an automatic transmission.

Yeah, back to old days there are many manufactures making all kind of automotive components. Now there are very few making those as you have to be big to survive. Small manufactures are keep fading away!

The description is vague, does each of those units have an issue, or was it a quality control thing where most are fine and only a few will ever present? It sounds like a tolerance was too tight and created a challenge during manufacture. Hard to say based on the description. Normally I'd think no big deal, except the fix is very expensive when out of warranty.

I just use my common sense. If you need a new configuration of the transaxle case to fix potential damage to the bearing, it seems all transmissions could have the same problem with old transaxle case.

I guess I'm glad I have a 2016 then. I always believe that never getting a first year product, especially on cars.

The AWD unit in my old '96 Ford Explorer is a Borg Warner 4404. I have read it is the same one utilized in the old GMC Cyclone and Typhoon performance vehicles.

I saw Mazda CX-9 has the same AWD unit as Ford Explorer, the same on its V6. Not surprising as Ford used to have major shares of Mazda. Unfortunately the AWD unit on CX-9 has issues due to the heat and compact size. Owners are urged to replace the gear oil in transfer case a lot more frequently than recommended.
