6 posts just to tranny
back up one , and see my answer.
what engine is in the jeep, Gas or Diesel.???????
what country? (diff, countries use different parts, by law or demand)
and what transmission options 4wd or AWD.?????
Please do say what knocks means.
check fuses yet, or tranny ATF fluid levels yet , not by guess? but by doing the steps for the A/T level checks, btw , its not done like the engine method at ALL.

here is a list of tranny squawks.(beefs, symptoms)
btw2 the FSM has a huge list of possible symptoms, ever seen and FSM, ? if not why not look there. it has a chapter called. has that too. read it. then ask questions.
ON CAR transmissing checks, diagnosis and repairs.
1: levels. (fluids) is it pink ,red, brown or black color. or silver flakes?
2: fuses. all.
3: TCM/PCM error codes. DTC'S errors. yes, scan it, i see you did.
4: tranny pump test. (FSM)
5: stall test. does the FSM stall tests pass , ?? takes 5min work (ask)
6: is the transmission filter clean? (yes, service does extend tranny life)
(ill stop here)
there is a start. we start there, then go further,
if really motivated, you can watch Duane's 10 hour Jeep tranny rebuild video. (ask)

there are a huge list of possible A/T errors. and issues.
from shifter dont move. (stuck in park) loose shifter, or?
stuck in any gear .
skips gears. (limphome does that)
car dont move.
won't upshift.
tranny slips. in any gear (aka: flares.)
will not down shift proper.
makes noises.
gets too hot.
the list really, is near endless.
does trans fail hot and cold engine or both?
is it leaking ATF.

most owner do not want to do the FSM tests
is that you?
you have 2 choices, RTM read the FSM do the tests
or take it in.
it is your choice.

what i do is make sure the TCM (function) signals are
good to the Tranny solenoids.
if yes, then the tranny is bad.
if tranny is bad, some can be fixed on car.
some even have bottom VB solenoids, that can be replaced on car
some Jeeps , this is near impossible.
i can show ,you the rebuild video showing that.
but why? are you going to do that?

i think you mean the transmission FLARES.
or (jumps to a false neutral)
If you allow it to do that , it will burn up clutch packs fast.
the more you do that , the worse the damage and parts needed.
the reasons for FLARE are: (at the least)
1: TCM make and error (or loose corroded wire ) .
2: the Shift solenoids failed.
3: that gears clutch pack is damaged.
4: low pump pressure. (or internal leaks or bad pressure reg )

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.

What would cause a knock in my engine/transmission when I am breaking from 20 to 15mph in a 2002 hyundai santa fe?

Depends on whether it is some internal knock or external to the engine/transmission. If external you will need to have the transmission and engine mounts checked.

If it is internal and definitely originating from the engine or transmission it is impossible to say what the cause is without testing the car. Changing the fluid in the transmission will not cure a knock of the kind you have described.

I just changed the knock sensor on my lexus rx 300 now the second and third gear dont have a smooth change also gear all of a sudden is not going into the 4th gear

Knock sensor controls ignition timing. It should have no control on transmission shifting. Did you disconnect/remove anything else to access the knock sensor? Was the battery disconnected? If so, a relearn procedure may be required for trans module etc relearn shift points while you drive the vehicle

Code p1763 means

the fsm covers that code and what to do..
P1 is factory code.
Gasoline engine, or Diesel.? if you dont know, that, then dont guess.
get it fixed.
knocks itself out of gear, what does that mean?

no mater, get it fixed, take it to any good ASE shop and ask them
but first check all fuse. in both fuse boxes.
Use a meter to do that, as ones that look good , can be bad.

I have a 06 ford fusion semi auto. After slowing down when it tries to pick up speed again, it flashes up transmission malfuction and knocks out of gear. Have to restart car to reset it. Put onto computer...

there is no way to tell weather it is a big job from a code, there are tests that need to be ran to determine what the problem is.sounds like it may possibly be an electrical issue with either the shift lever itself or the valve body on the transmission

Knock sensor

Nope. The knock sensor detects knocks in the engine and retards detonation in the timing.

Car not shifting would be bad vacuum operated actuator on outside of tranny or bad syncros or other internal transmission parts

Transmission Knock

this is most likely a transmission filter being dirty and it needs to be changed regularly as does the oil in your van. this is inside the transmission and needs to be serviced to complete this job i do not recommend you trying this by your self as you could damage your transmission.

1997 Nissan Quest knock sensor and transmission

A knock sensor going is usually indicated by pinging/rattling noise from engine especially when accelerating up a hill or just giving throttle but not kicking down a gear. Not sure what your asking about transmission?
