Problem with my 1999 Chevy Blazer
Engine size 4.6 liter
Repair work done prior = Rebuilt transfer case installed in 2007 installed.
Question = My Blazer has push-button 4WD. During normal driving the 2-Hi indicator is
lit. However in recent weeks I've noticed that this light is going off for short periods of
time. It eventually comes back on, but I'm worried there may be a problem with my
transmission. Any ideas what might be causing this? Thanks so much for your help!

Answer: Well, first off. This would not be a transmission problem. This is
only related to the 4 wd. Transfer case.
There are three common failures. Listed from most common and
inexpensive, to most expensive...
1. The actual 4 wheel drive switch in the dash. If the lights are acting up
but no change in the truck actually being in 2 or 4 wd, most times it is a
faulty switch.
2. The transfer case control module is acting up. This can also cause this
lighting problem. It is located under the passenger side of then dash. Have
had a few go bad, and also a few go bad because they got water in the
electrical connector. Unplug the module and look for green corrosion on
the terminals.
3. The "Encoder Motor" This usually causes problem when trying to shift in
and out of 4 wheel high or low. A faulty encoder would cause it to not
change gears, and would also set computer codes in the module.

93 Chevy S-10 Blazer Engine 4.3L Vortec.
Repairs for this problem = changed transmission fluid and filter.
Question = I recently sent in a question, but I'm not sure with all the other ones your all getting,
if you either over looked it or it didn't go through. Anyways, I have the 4L60e transmission in
my 93 blazer and its not working very well. I am wondering if there is another transmission that
will bolt up to my 4.3L? Someone I know has one out of a 87 blazer, but I think it is a 2.8L V6
instead of the 4.3L. The bellhousing looks to be similar, but was wondering from your
experience with transmissions, and GM cars if it or another one would bolt up?

Answer: The older Blazer trans would not work. Totally
different animal. Any 4l60 E transmission ill work from a
similar truck. Best is to go to the dealer with the VIN
number of your truck, and get the part number of the
trans and have them print out the list of years, makes,
models that part numbers also goes in. Then you would
have a list of vehicles with this trans.
