transmission control module is not getting enough electric power. Is the transmission working OK? Might just be a bad connection. I do not have the wiring diagrams or I would try to direct you better.

2002 axiom transmission only goes in reverse and first

scan it yet
the TCM must be scanned
fuses checked
levels checked( done right never overfill it or do it like and engine)
wiring look ok to it?

The TCM is the tranny brain
no matter where it hides
and does all upshifting and down
seems its
1: dead, or lost power. or has errors.
The TCM has many inputs, and if inputs are wrong outputs (shift solenoid) will fail.
its just a small computer, and must have good inputs to work correctly and must be scanned first.
after fuse checks.

When I first got the code p0882 it told me that transmission solenoid need to be replace because when I drive it was fine until I got ready to go over 40

code p 0882 refers to transmission control module (TCM)--power input signal low === causes ---wiring, short to ground ---TCM
what ever solenoid that was replaced would not fix that code so it would have involved moving wires that improved the problem
code p 0700 refers to transmission control system/MIL---malfunction=== causes -- wiring --- TCM
code p 0562 refers to system voltage-- low === causes wiring ---poor connection---battery--- alternator
it also refers to --ECM power relay control---circuit open===causes ---wiring -- ECM relay
the first 2 codes could be influenced by the last one so have the an accredited auto electrician check the charging system and ECM relay and then check/ replace the TCM if the wiring is good

Can a bad knock sensor cause a tranny to go stay in 2nd gear(limp mode)on a 2008 dodge ram 3.7 liter.Got 2 codes a #2 knock sensor and tcm power low voltage

The transmission is in limp-in mode because of the second DTC - TCM (transmission control module) low voltage. The knock sensor code has nothing to do with that. You need to have the TCM and transmission checked out.

wow no year stated, its 1996 and never but how new
its a KK or KJ jeep 2002 to now. 14 years of jeep.
as is what transmission used, and if 2wd or 4wd.????
first the p0700 code
ONLY, means
1: SCAN TOO you using is junk, and old,
2: means the TCM needs to be scanned by self. to see all codes in the TCM.

my guess is you need a real scantool..

700 means, trans has errors, stored, ASK IT NOW.

1: fuses good,
2: is TCM plugged, in? some Liberties have seperate PCM and TCM.
3: the TCM most see all sensors working (where ever it hides)
if not , it will not ever upshift.
speed sensors dead, or not plugged in?
PCM cant talk to TCM.// oops....
and more.
the problem is your tools, (missing a real jeep scan too)
my INNOVA 3160 can see those errors, but ive never done a liberty, in fact i don't consider it a real jeep.

The TCM is JUST a computer (a simple microprocessor)
it has inputs and outputs (shift solenoids)
if the inputs lie, it can not shift or shifts wrong, or goes to limp home and skips gears.
all TCM work like that, and not scanning it is a FAIL.

you must scan it fully. to get all CODES.
