How many plugs have the tcm have on a jeep cherokee 3.7 auto

Disassemble the TCM and use magnifier to check the solderings of both plugs. If you can see any circles on the solderings then resolder them. You can resolder them for "just in case" as well. TCM is located on the right side of shifter assembly, near the passenger legs.

what car.? name it? it has a name. Cherokee, wranger grand.... what/?
jeep tells, not much
automatic or manual.
some autos do have TCM box (getting rare these days)

others newer the TCM moved into the ECU and became PCM
which engine, as transmissions match engines.
and what country?> as we USA have 2 engines and others have vastly more choices.
see?
we have no idea al ALL what drive-train is in there.
ill pretend you said cherokee.
with the 4 liter engine. I6, 6 banger , INLINE
i open your FSM book and look
and here is the XJ TCM

that depends on opted drive line parts, 4wd and transmission.
the book is here
read it.

42/44RE auto trans, TCM?

read chapter 21. it covers the whole deal.
there is no PCM
like most cars , this era, they moved the TCM in to the confines
of the ECU , and renaming it PCM on that idea.
read page 21-6 carefully.

Check on your motor you have some where a place how you have your number of your celynder

did you scan to PCM to see if there are DTC errors from the TCM
the TCM is the logic that runs the transmission.
why assume it the TC or tranny, why not suspect engine misfire?
again scan it. (or get and engine tune,up, )

Dtc p0935 easy federal code P0.
first hit in google, google is your friend.
read that and then ask questions.
or you have tools ,and training, , you and read the FSM
the FSM discoverers this 100% .
or do this:
1: reset the ecu.
2: drive and see if it comes back.
or
3: get radio codes, RTM , if not the radio may brick on you, RTM.
4: the pull battery neg. lug for 5 minutes, some step on brake and shorten this time but not me i do both. I want 0volts to a puter brains in car. then you get a full reLearn.
5: then drive. see if comes back.

this is true with all DTCs, the hope thing.
reset
drive 20miles, and drive aggressively, (safely)
see? it it returns......

as you see the tranny dont like open loop (means future damage)

code p0935 refers to hydraulic pressure sensor--circuit high input===causes --wiring--short to positive--hydraulic pressure sensor--ECM/TCM--TCM -transmission control module.
. Have a pressure test done on the box to ensure that the pressure is correct and that there are no internal issues. Most issues concern the TCM

Transmission tcm relay or tcm trans control module

hi the TCM is under the dash on the driverside. It's actually kinda of small, I would guess 4 inches by 3 inches. with what look like wings coming off the sides and two bolts. hope this helps please vote thanks
