Re: 1989 Suburban 2500 Full L83 6L80 build

Well, I have a bit of upsetting news. Fully ready to drive the vehicle yesterday I took my time to make sure trans fluid was topped off (which I think it was slightly overfilled as it never actually went down after initial 5 or 6 quarts) and trans shifter linkage was working perfectly before giving it a go and what do you know, no dice.

No movement, no noise, no clunk, no engagement, nothing. Now I know when you remove and install the TCM you have to carefully align the PRNDL switch and valve rod with the shift linkage. Fully confused I took it apart double checking everything to ensure I didn't mess anything up. I have had it correct every time I've removed the TCM which is 3 times now to ensure it wasn't something I was doing wrong, I know it had nothing to do with the Torque converter install as I never removed the torque converter and it was fully seated before I bolted trans back to engine and spun freely.

Long story short, the pump isn't working for whatever reason. Fill up fluid, run through gears and nothing. Fluid doesn't go down, nothing happens.

Talked to the place that sold me the engine and trans and they are going to work with me once I have a proper diagnosis from a transmission shop to get a replacement and or reimbursement.

Just sucks because I was totally driving this thing yesterday in my mind. Looks like we're going to be another few weeks away. Cars and Coffee was this Saturday too, better luck next time I guess.
