TC fluid looked like red metallic paint

First change after installing a NP242HD from TCU. I am hearing a rotational rubbing (sort of) noise in 4wd, but not 2wd, but not certain where it is coming from. There was a LOT of metal in the ATF +4 IMO. TCUGeorge said to run 5w30 syn motor oil but I didn't. Is this normal from breakin? Any speculation is appreciated.

Always do as told even when it sounds odd. my T5 that is factory ATF both a GM tech and junk yard aid run 30W motor oil if I want it to last. I run 30W motor oil in it.

Have heard this before even back in the day when there was only dextron. The reason is that atf doesn't have adequate lubricating properties.

ATF is thin to begin with, but it gets thinner when hot. I had a T56 6 six speed that required DEXRON 3 and my go to trans guy said he put 30W in the ones he rebuilt and never had a comeback due to bearing or gear failure.

You can run anything in the transfer case BUT if/when the transmission output shaft seal goes then you can contaminate (and possibly damage) the transmission. This is the reason they recommend ATF+4. Cheaper to replace a transfer case than the transmission.

Only two things come to mind when you mention rotational rubbing.
Planetary or chain.
If its aluminum you're seeing its the chain,if its steel, its the planetary.
Take a magnet to it.

thx for the replies
Should the pickup tube filter be dangling loose near the drain hole? Or should it be secured down tight?

Secured tight,it kind of snaps into place.
Easy to misplace while assembling.

Yeah, the case halves have a slot to hold it.

This should only happen if someone has used sealant between the transmission and tcase and both the output seal+input seal have failed.

If the filter got misplaced during assembly, would that affect internal lubrication? It appears the tube is connected at the top, but I can move the filter away and toward the drain hole. It won't move upward or sideways, just back and forth away and toward the drain hole.


I sent George and email to see what advice he has.

I watched a video of a rebuild from a thread here.
The guy made it sound pretty damn important to not forget to make sure the filter was in place and hooked up.
There is an "O"ring where the pick up tube connects to the pump.
The oil pump in the TC isn't something like we think of when thinking about them.

If the filter screen isn't installed right the pump might not be able to keep things lubricated.

U will have metal from the chain

Itís a common thing with the large coarse chain

Itís new need to wear in
Filter is normal it is not clamped down
Noise in 4wd can be a lot of thing but not in the tc the load can cause a noise but the tc turns all the time in 2wd
