Question about 1998 Chevrolet Blazer

1 Answer

99 Olds Bravada Smart Trac shifts hard from 1st to 2nd. Shakes and sounds like front axle is binding when you first start off and clicks a couple of times if your turning. I'm replacing Trans. filter and fluid now. Should this solve the problem?

I have a 93 jeep Cherokee, it will move in 4wh and in 4wl but will not go back into 2wd?


Hello guy
try posting what 4wd system you have,? first.
command trac or select track, (the latter is full time)
part time or the full time system,
we cant guess it....
read the operators guide first, if a part time system only
as i suspect, stop driving on dry pavement.
it's only for ice, or dirt. part time. part time is not a full time system.
Command-Trac
shifting to 4wd on dry (means no ice) pavement causes, drive line wind up! and the gears to lockup. (see steering get tight in turns?> and is dangerous to drive it like this , you, me and the box)
posted here 100s of times.

http://www.rubicon-trail.com/4WD101/driveline-bind.html


the non grand Cherokee. early

had these choices
  • 1987-2001: New Process NP231 Command-Trac, part-time only, 2.72:1 ratio with low range
NP231 has the following settings: 2HI, 4HI, N, 4LO
  • 1987-2001: New Process NP242 Selec-Trac, full-time or part-time, 2.72:1 ratio with low range
NP242 has the following settings: 2HI, 4 full-time, 4 part-time, N, 4LO


as you can see you need to first know, what NP box you have or
photo your shift lever for 4wd, an post it and we tell you.

more facts, on select trac. (totally unlike command trac)
Selec-Trac locking hub is used on 4WD Cherokee. Selec-Trac
utilizes a non-disconnect front axle. Engagement of 2WD or 4WD is
accomplished at transfer case by means of mechanical shift linkage.
System allows full or part time 4WD. Selec-Trac can be shifted into
2WD or 4WD modes from inside the vehicle at any speed.
unquote
next from the service manual,
4WD TO 2WD
1) Place mode select switch in 2WD position. Transfer case
should shift to 2WD and not allow shifting into 4WD or LO range. Axle
should shift after transfer case shifts.
2) To determine if front axle has completed a shift out of
4WD into 2WD, position mode select switch back to 4WD position while
operating vehicle at slow speed. If vehicle shifts into 2WD, axle will
ratchet. If shift is not completed, transfer case will shift into 4WD
and hissing sound will come from mode select switch.
end quote.

if unsure read the FSM book its free.
shows you both systems and how to diagnose it.

in the box, click Cherokee,,then click 1993, and behold.
the real deal.

Just had the reverse hub replaced on 2000 olds bravada. drove it approx 20 miles, now service engine soon light is on. Shifting feels alittle funny and almost feels as if motor is bogging down. Could...


This is an electric shift transmission (4L60E). If the harness is not plugged in well enough or has dirt in the plug it can lose contact causing it to seem as if it is bogging. What is essentially happening is that it is starting out in 1st initially, but when you slow or stop it doesn't go into 1st again and tries to go in 2nd. You can go undewr the truck and check th connection. If this doesn't resolve the issue, I would return the truck to the repair shop and have them check to assure that the plugs are correct in the valve body driving the shift solenoids.

1999 olds bravada smart trac four wheel dosent engage


Probably the transfer case encoder motor. Unplugging it at the wiring harness should make the "service awd or smart trac" light come on. This will tell you the awd controller module is probably OK. Common failure item to Bravada's. Try "thepartsladi" eBay store for lowest price motor, beware aftermarket!!! Also make sure transfer case fluid is "blue" GM Auto-Trak II only! If not bllue when checking change twice after driving for a week with blue fluid.

drain the transfer case and check for metal particles in the fluid, there also may be debris bigger than that, try the fluid change in any event then if that doesn't do the trick you will have to overhaul the transfer case, this is a standard transfer case used by light duty trucks and SUV's based on a truck chassis, not the viscious drive type used bt passenger cars like Suburu
