Just a quick update:
- I picked up a Gen 2 6T75 from a 2015 Buick Enclave at the JY for $1000. It reportedly had 10 miles on it. Yes, only 10. It must have been a freight damaged vehicle. I have the VIN, but didn't pay to look it up. If anyone has a subscription to a VIN check, I'd be happy to share the VIN to confirm.
- After pulling the trans out, I swapped the valve assembly and TEHCM from my Gen 1 trans to the Gen 2. This was to make it compatible with my model year and avoid dealer programming.
- I suspended the engine and steering rack, but removed everything else from the bottom (exhaust flex pipe, transfer case, subframe, left cat converter, starter, trans). I disconnected the propeller shaft at the transfer case and secured it up, not removing it. I hung the calipers on the strut assembly. The CV half shafts were removed with the hub, knuckle, and rotor attached, disconnecting the knuckle from the strut. I also took out the fender liners to make it easier for the other jobs.
- I installed new GM subframe bushings, new KYB front struts, new GM subframe mounting bolts (8 bolts of the 12, the 4 smaller bolts for the rear end aren't called out to be replaced), new GM front and rear engine mounts (with new nuts purchased from McMaster Carr -- where I also bought 2 threaded rods to serve as guide pins for the transfer case install), new GM trans mount, new GM transfer case o-ring (where it meets the trans), new MOOG sway (or stabilizer, whatever you refer to it as) bar bushings, and new exhaust gaskets/seals (2 Felpro for the flex pipe to cat, 1 GM from the flex pipe to rear main cat, and 1 Felpro seal for the cat to manifold).
- I've put about ~50 miles on it so far and all seems well. I just need to get the car aligned to finish this up. Doing this without dropping the engine or complete subframe assembly was a PITA and likely greatly increased the duration of the job. It was done this way because of the type of lift I had access to (4 post). A lot of time was wasted fussing with gaining access to things and lining things up. In all, it took about 4 long days.
- Does anyone need a valve assembly and TEHCM for a 2014-2016 Lambda?
