Another problem with Teflon and while most will never encounter such a issue is that the more you complete wraps you make the thicker it becomes. This doesnt sound like an issue untill you start considering high pressure systems when with to many wraps you actually decrease the shear value...
There is actually a Teflon specific for oil / gas and wont breakdown whereas the usual white stuff is rated only for water. You may have used it for 25+ years as many of us have teh two major problems is that if you get any gas, diesel or even oils it will start to breakdown. That and the fact...
I use to use Teflon myself untill I found out that it can allow rust through it and with higher temps it also breaks down. If you are gonna use it be sure to get the teflon thats rated for gas not the regular white stuff for water
Just doing my 94 Tranny as we speak. 94 K3500 Diesel tarnny's are only interchangable with 94's. Its because of the electronics. I have the 4L80E manual and it also states there are a few differances as well.
94 K3500's used the BW cases. Look on the back side you will see 2 plugs fairly close together. One is at the bottom and the other 1/4 the way up. They take 1/2 inch ratchet if you are lucky, if not breaker bar. Do yourself a big Favor and remember to use Never Seize before you replace.
Funny you ask,
I have a 94 K3500 4wd myself. There are two plugs and yes they are fairly close together. The upper one is in fact the fill plug and you dont want to overfill them either. You have a BW4410 / 3710 Transfercase.
I had to use ALOT of force the first time to get the plugs out...
Okay so it started with great intentions, my tranny is in getting rebuilt but the transfercase is on the bench. I started out by wanting to r&R the gaskets and do a complete inspection inside(why not got it opened right?). The problem I have is that I cant find any information, manuals, diagrams...
