ok, I got the vacuum line all fixed up with tubing, but on a jaunt out today, the vents were acting a bit weird, so I'm going to change both check valves.

I bought an o-ring and put it on the transmission dipstick housing. No leaks, but the truck was acting a bit sluggish at times, so I'm thinking I need to drain the tranny fluid and put in ATF 4+, as it probably doesn't have that right now.

Any thoughts?

 

Somehow I don't think it's your tranny making it sluggish. Read the plenum sticky on top of the threads.

 

oh yikes, that plenum install might be beyond my abilities/time/tools. I'll have to see if I can get a small mirror in there to see if oil is pooling. I will also go ahead and change my PCV, just in case.

 

Make sure you get one from the dealer.

 

Get the PCV valve from the dealer?

I got one from Autozone, dropped it in, and it doesn't feel sluggish anymore. I also found some vacuum check valves to address my "wacky vents" issue.

I'm hoping I don't have to change the plenum, but I am going to check on it tomorrow with the magnet test, the mirror test, and see what happens.

 

my wacky vents were fixed for a little while, and now they've come back. I'm going to check the new CVs, but I imagine that I've developed a vaccumm leak somewhere.

Another small issue that has popped up. The 4WD light comes on. If I shift into 4WD, then back to 2WD, it turns off, but then will come back on in about 5 minutes or if I turn off the engine. Is this the sensor acting crazy or what?

 

Either the switch in the cad being weird, or, you have some vacuum lines backwards.

 

do you know to test the CAD switch? And as far as the vacuum lines, could a leak cause the issue? I don't understand the "backwards" comment. How can a vacuum line be backwards?
