L52 it's not accessible without taking the tranny out. No, haven't talked with them yet but I'll be calling tomorrow if I get a chance. Won't be getting it to Marlin's shop, since I live in Montana. This is the crappy thing about getting a "modified" transmission...if there are issues (which there really shouldn't be so soon), it's going to be a bit harder to figure out what parts are right.
There's a chance that all my other noises and rumblings are other parts of the truck. I just rebuilt my t-case, and though I feel that I did everything right, it was my first one, so who knows, maybe I messed it up. But my tranny is definitely popping out of first, and neutral feels very strange right now. Sucks cause this is my DD and only vehicle.
