I could use some more advice & a sanity check. I feel like they are doing a bait & switch now that they have my ride in their shop with the trans out. Costs keep going up. I’m attaching their initial report and the 3 options they presented (2 rebuilds & 1 GM reman swap in)
I’m located in...
I like it. Basically a glorified T into the evap purge line? I’m starting to look into vacuum pump removal since I’m now out of warranty and have DoD turned off. Couldn’t believe one of the most popular YT videos on the subject instructs folks to delete PCV
Hope it’s okay to bump an older thread. I’m considering this for my ‘17 Tahoe since it’s about to get a tune pretty soon. Just curious what sort of power gains are possible with this on a stock motor?
Thanks for replying! I didn’t even know that you could tune tow mode differently than non towing. I need to find a good tuner, doesn’t need to be local since I have HPT and can pull logs & load files.

Bueller??
Trans shop just called and after pulling the pan confirmed that it needs a complete overhaul. $7,500 Fakkkk.
They said they use upgraded TC and bypass the thermostat on all rebuilds but recommended against tuning the TCC differently. Wonder why??
For those who’ve had theirs rebuild...
They should call it generous motors for sure. At this point I’d be happy with the relatively low price tag of $5,100. What area are you in. I’m in Western WA on the peninsula
Hello all,
I’m new here so hopefully posting in the right place. Made an account to solicit some advice on my current situation.
Our 2017 Tahoe has about 127k on the odo now. Got it a few years back with about 90k and immediately turned off AFM with an OBDII dongle. I don’t think it’s ever had...
