Miss firing& trans is slipping - 2006 Jeep Liberty

Have to rebuild the transaxle

You changed the fluid on an already slipping
trans,now it is worse.

Too old a vehicle to put time & money into

I owned a trans repair shop in the early 1990's
& 50% of my work was caravans & taurus ,so that
tells you their not a good unit at all,only the ford
windstar & it's replacement were as bad or worse

MANUAL TRANSMISSION, CLUTCH SLIPPING
AUTO TRANS. CHECK FLUID, IF LOW ADD
CORRECT TYPE OF FLUID, IF BURNT SMELL
HAVE DEALER CHECK

Hi Mike, Seems to me you have an electronic management problem. The fire must have caused short circuits and has maybe damaged the on board computer. Sort out the short circuits first and then carry out another scan and see what comes up. The traction control is incorporated as part of the ABS system, using many of the same sensors for operation. The problems you relate can have been caused by incorrect signals from the management system. regards John

When a transmission slips & you continue to use it,
you burn the clutches & it has to come out & be rebuilt

The PO758 is Solenoid B inside the trans pan

If that trans is original from 2001, don't waste your time
with the solenoid,rebuild it,once they slip your done,
unless the vehicle is only a couple years old & you
come home immediately when you notice slipping
& get to work on solenoids

Can't fix slipping

Once that starts your only option
is a complete rebuild

My advice is to change the fluid every 3 years
& don't flush,just remove the trans pan

Second --once you notice any trans issues you
immediately return home & park it until resolved

90% of all trans issues are a result of not doing that

I once owned a trans shop,but that is my personal
experience & opinion,the professional part , doesn't
hurt the learning experience

I had a similar problem thinking my tranny was slipping. Turned out it was the spark plugs miss firing, had 100,000 mi. Changed the plugs & wires problem went away.

At this point you need a complete rebuild
Once the slipping starts the clutches are burnt


After the trans is broken down then you may be
told what caused the problem but I doubt it

If you don't change the trans & power steering fluids
every 3 years you loose the trans & the steering rack
will be next & then all your other vehicles the same

Same for brake fluid--every 2 years or big dollars
for ABS Unit

I'm sorry ---but any transmission that is slipping usually
has been doing so longer than you recognized it

The only fix is a complete rebuild when the slip

Slipping is from not changing the fluid every 3 years or
30,000 miles. It breaks down from the heat & so goes
your clutches & the slipping begins. Not a secret,it is
pretty well know fact of the last 55 years or so

One fluid change in 120,000 miles & your near the end
of a trans life expectancy,some keep going,not many

On the yearly side,you can go 3 years or 18 years,
seldom without fresh fluid & very gentle driving habits

I believe yours is electronic & no cable to adjust
You can look next to the throttle but you'll never get
that spot that will stop slipping

Change the fluid now & it will slip for sure

No additives ever go into a trans,just the correct fluid

The P1320 code is essentially a coil primary voltage problem. This is traceable using a labscope or accurate DVOM and perhaps you can isolate one or two coils that still work but are close to failure...but there is a nissan service message recommending replacement of ALL coils with updated/improved models to prevent this type of failure. TCS/SLIP is traction control. Most likely you have a speed sensor issue. Be aware, some vehicles can falsely illuminate TCS because of low tire pressure in a single wheel.

My 2003 Siverado has 65.000 miles on the automatic tranny. It is starting to slip going from 2nd gear into 3rd gear. Do I needa rebuild or what?. Thanks.
