Hello, This is a 1999 Chevy Silverado 5.3l, 4wd push button style, 4L60E transmission, 153k. I have a green fluid leak (T-case fluid) coming from the front axel input shaft seal, drivers side. It obviously gets thrown around all over surrounding components when driven in current condition. The leak will accumulate about 2 or 3 drips on the ground overnight. It's been going on for a good while judging by the amount of fluid caked on everything. I've only driven approximately 50 miles since i noticed issue, all in 2wd. My questions are whether or not i risk significant damage to the case if ONLY driven in 2wd while also adding fluid as needed? Also, is there an "inner" seal in the transfer case that will be exposed when drive shaft is removed from t-case? If so, what is the responsibility of "inner" seal and is there a reason it should also be replaced simultaneously? When i'm in that deep i'd rather do whatever is necessary and logical. Thanks for any help with stated questions and I also love to hear any related advice or experience! Taking it to a shop is not an option as I have little money and major trust issues. Trust issues stemming from several bad experiences in the past and most recently, pertaining to this vehicle. I bought this truck for $6,500, everything is in VERY good shape, recently had a 90k motor installed @ 150k (i purchased it at 152.5k) as a private party transaction from the auto shop owner who installed the second motor. Turns out recently installed engine either has a cracked head or head gasket as the black light test reveals coolant coming from exhaust among other confirmations... AAAGGGHH. That's a completely different story that's being dealt with but figured i'd share my reasons for NOT TAKING IT TO ANYONE mentality. Auto salesmen/mechanics can be total sleezeballs. From now on it's my way or the highway, to my own dismay haha.
Sooo.. 1999 Gm Auto Trac (4 button) transfer-case calling for the soon to be OBSOLETE Dexron 2 Anyone know of any non GM (RP maybe) fluid company that makes a synthetic variant of Dex 2 for THIS case because I heard its about to be dis-continued. I have been at this for most of the morning and I got SO much conflicting advice from all over spanning from 2% milk to soy-bean oil and I have no idea whats help and whats BS. I know what putting the WRONG oil in it will do. But I wonder if there might be a aftermarket oil I don't know about that is as good, if not better then OEM.
