2010 Suburban with Transmission problems

[Abdullahredwan]

Hello everyone
This is my first post here on the forum, so please excuse me if this is not the right place to post.
Long story short, bought a used 10 suburb with 110k miles on it 6 months ago. Upon inspection, i noticed that the transmission fluid was brand new and the previous owners assured me that he kept maintenance and service a priority.
The issue started a month or so back, the car would jerk when shifting, sometimes also taking longer than usual and having to rev the engine pretty high in order for the tranny to shift. Took it to a shop, had it diagnosed. The only code in the engine appeared to be a p0573 (brake switch)
The transmission control module came back with 4 codes: P0842, P0872, P0877, P0898.
The shop wanted to tear apart the transmission and gave me an estimate of around 1.5 to 3k USD
Figured I would ask here first, the last thing I would wanna do is start tearing things apart. Also, can the faulty break switch be causing all this stuff?
Any feedback is greatly appreciated!

Welcome from SoCal, where ya at?

Not the brake switch doing that but do verify your brake lamps are working.

You’ve got enuf to go back to the seller and let em know you took the truck to the same place he did and they recognized the Burb and pulled up the following codes.

Play poker with him. He gotcha on a known bad trans after the trans service he did, didn’t fix it.

Ask for 1-$1.5k back or a promise note from him on the spot already written out for him to sign or you’ll call your brother in law who is a cop.


Again, play poker and see what happens. You’ll need about 3-$4k when it’s all said and done.

From there give yourself a pat on the back because you’re good for about 100k miles on the new trans in one of the most highly sought after, otherwise reliable trucks.

Unfortunately, that won’t work where I live. I’m in Dubai and people here aren’t quite as “forgiving” to say the least as people in the US
So, I’m guessing the trans is toast, huh? I honestly have no idea how big or small of a job this could be, but from what you’re saying, the transmission needs replacement?
