I was just under mine finishing skid plate installs today and replacing tc vac. switch (found one at another dealer). Saw what you're talking about. Not saying what you're talking about couldn't happen but it'd take one h**l of a bump to do that. I have not had one of the 233 t-cases from a CC apart but the older models all had a sort of splash-guard in them to prevent what you're expressing fear of.JaVeRo wrote:I could see it happening real easily, bouncing thru a mud hole and sloshing some fluid from the transfer case into the vent line, then you take it out of 4wd and the fluid gets sucked up toward the motor.
Don't sweat the small stuff. If, you have 77K and everything is working then you have a little time to play with. The time to worry is when you find ATF in your ashtray.Jongo8 wrote:After reading this I'm worried to death............
If you have no fluid in the lines the next place is to start checking ALL vacuum lines including those by the master cylinder and those to the vacuum pod that engages the 4wd under the battery. Especially since you've lost heater/ac vacuum door control.MCbowhunter wrote:Gents I realize this is an old thread, but I just found it last nightwhile looking for any clues as to why my truck would not go into 4hi. Just recently my truck started to not blow through the vents on the floor. Anyhow I went to the dealership today to buy the Transfer case vacuum switch. I bought it at cheap price......$60
maybe inflation?
However now I know that I will have the peace of mind in knowing that it is the good one.
I have not gotten under the truck yet to see if there is any fluid in my lines. We shall see soon though, it will be here Monday. Just wanted to give any body that hasn't gotten the switch yet a heads up.
Got my switch today, only took 10 daysHorsehammerr wrote:Just purchased P.# 89059420 switch at GMPartsdirect for $29.47 + $10.97 S&H = $40.44
