Well, my transfer case swap nightmare continues. The story: my NP246 TC was making noise, found a "remanufactured" one on CL for $500. Installed and thought I was good to go. First snow comes and 4WD is not working. Then starts making a bunch of racket. It's my wife's daily driver and I don't have time to mess with it so I find a guy "with 20+ years of experience at AAMCO" who says he'll pull the case and replace whatever needs replaced for $300-$700. However after looking at it he tells me that nothing in the case can be saved (he says the oil line fell out of the pump) and will have to find a builder case. He calls back and says he found a case that was rebuilt recently then the truck was totaled. He'll install it and give a one year warranty for $850 (of course it then turns in to $900 when I go to pick it up). I get it home and notice transmission fluid is leaking. I get under the car and can see that its leaking where the TC mates to the transmission and there is no gasket installed. Then I decide to check the TC oil while I have it on ramps. Pull the fill plug and it seems low on fluid. I pull the drain plug and the fluid (red tranny fluid, not AutoTrak fluid) is dark and cloudy- this is after 4 DAYS! I'm pretty upset at this point and go back to the shop to talk to him. I tell him it's leaking because he didn't install a gasket. He tells me that it is a "dry" connection between the TC and transmission and that no gasket is needed. Is that right? I thought the back of the transmission (it's a 4L60) was open and that a little tranny fluid get's in that connection. Who's right? Do you need a gasket there (it's a paper gasket from the dealership). He's still claiming he cracked open the case and installed new fluid but said he would drop the case and look at it to see what's going on. I also asked him about using autotrak. He said that he adds the friction additive directly to the tranny fluid and that its the same stuff, just cheaper. Thanks!
